Air Purifier: When an Air Filter Is Not Enough

Friday, June 6th, 2014

The air filter in your air conditioner does an important job: it helps keep dust and dirt from accumulating in your system. This can improve the air quality in your home, but that is a secondary feature of the built-in air filter. If you need to improve your indoor air quality, the best place to start is with a whole-home air purifier from Climate Masters – your St. Augustine air cleaners.

What Does an Air Purifier Do?

An air purifier takes your indoor air and passes it through stringent filters that capture different types of particles existing in your indoor air. Air purifiers purify the air with this process, filtering the air in your home so that it becomes cleaner.

What Types of Particles Are Captured?

Air purifiers are designed to capture:

  • Dirt
  • Dust
  • Allergens (pollen, pet dander)
  • Smoke
  • Mold spores
  • Bacteria
  • Viruses

Understanding MERV Numbers

Just as an air conditioning system comes with a SEER number, a whole-home air purifier comes with its own number, too, called a MERV number. MERV stands for minimum efficiency reporting value, and it measures the level of efficiency at which an air filter functions. The MERV scale starts at 1 and ends at 16, with 16 being the most efficient. Our minimal MERV recommendation when choosing an air purifier is 8.

Why Install an Air Purifier?

There are several reasons our customers install whole-home air purifiers:

  • Helps relieve allergy symptoms
  • Helps relieve asthma symptoms
  • Increases overall indoor air quality
  • Further reduces the presence of dust and dirt

What Types of Air Purifiers Are Available?

There are several types of whole-home air purifiers from which to choose:

  • High Efficiency Filters –high efficiency filters are great at removing pollutants from the air, such as allergens, smoke and pet dander.  However, it is important to have a professional install a high efficiency filter as some may constrict air flow in your system.
  • Electronic – using an electrostatic field, an electronic filter pushes particles into a confined space with a fan, electronically charges them, then attracts the particles using an opposite electrical charge. These filters are highly efficient and require fairly minimal maintenance.
  • UV Germicidal Lights – UV germicidal lights use a safe amount of ultraviolet radiation to destroy biological pollutants in your air conditioning system. UV germicidal lights are excellent for destroying microbes, mold and mildew spores, and harmful bacteria and viruses. However, UV lights do not have a filter, so they do not help eradicate dirt and dust

How Does Zone Air Conditioning Work with Ducts?

Friday, May 30th, 2014

Central air conditioning is a wonderful invention, but it does come with an inherent flaw: when the AC turns on, every room in a home that is linked to the ventilation system receives the cooled air. Even rooms that don’t need them, like an empty guest room. Rooms that need cooling, but not as much, like a baby’s bedroom, still receive the same level of cooling as the rest of the house. People who have different comfort levels will feel uncomfortable while other people will feel just right.

There is a way to get around this problem, and that’s with zone control. You don’t have to put in a new AC to enjoy the advantages of zone air conditioning in St. Augustine, FL. With the right installers, such as those at Climate Masters, a new zone control system will fit right into your ductwork. This basic retro-fit will provide you with a new level of comfort and energy savings.

Here’s how zone control works with your existing ductwork

When installers come to your home to provide you with a zone control system, they access the ventilation shafts that lead to each of the “zones” of your house. (You decide how many zones you want. It can be as simple as “upstairs” and “downstairs” or as intricate as every individual room that is linked to the ductwork.) The technicians fit a damper into the duct, which can open and close. The damper forms a tight seal so they can effectively cut off flow to the zone.

Each of these dampers then connects to a zone thermostat, which controls that damper. This is important, because it permits individuals in the house to control the temperature wherever they are located. Each of these new local thermostats then connect to a central control panel, which gives you full access to each of the zones from a single location. You can program them for maximum energy savings.

Have professionals on the retro-fit work

This all may sound like difficult work—and it is indeed complex. However, in the hands of experts, the job will go fast and you will soon enjoy the comfort and the savings of a zone control system. Don’t attempt to do this work on your own, nor delegate it to an amateur who makes claims about performing the installation “cheap.” The work will be cheap… just not in the way you want.

We have years of experience doing this work, and we have all the necessary equipment on hand to take care of it quickly and effectively.

Call Climate Masters to find out how we can fit your current HVAC system to deliver zone air conditioning to your home in St. Augustine, FL.

What Does the ENERGY STAR Sticker Mean?

Friday, May 23rd, 2014

When you are looking for an air conditioning replacement in St. Augustine, FL to prepare for another heavy Florida summer, you will come across a slew of statistics, brand names, types, and sizes that may start to feel overwhelming. Among all this data, you will also spy a sticker on many air conditioning units: a blue background with a white five-pointed star and the capital letters (always capital) ENERGY STAR. This looks important… but what does it mean?

If you have a professional installer working with you (and you should), he or she will help you understand the complexities of air conditioner models to find the right one for your home. The ENERGY STAR label will play a part of this, and chances are high that you’ll end up with a system with this sticker on it. We’ll explain why.

If the installer at your side is from Climate Masters, you can rest easy that you are receiving experienced and qualified service from one of the best heating and cooling contractors in St. Johns County.

The ENERGY STAR program

The ENERGY STAR label indicates that an appliance meets the standards set by the ENERGY STAR program. The U.S. Environmental Protection Agency (EPA), under the authority of the Clean Air Act, established ENERGY STAR as a voluntary program in 1992 to help homes and businesses save money with energy-efficient appliances and protect the environment from damaging emissions. Manufacturers of appliances can choose to submit their product to the scrutiny of the program. If an appliance meets a set of regulations for energy efficiency and low negative environmental impact, it receives the label as a sign of approval.

The regulations differ depending on the appliance. With air conditioners, a system must have non-proprietary technology to achieve its efficiency (i.e., no single company can have a monopoly on energy efficiency), contain features that customers in general demand, and return on investment on its installation after only a few years if it costs more than a non-qualifying system.

A very specific AC requirement for the ENERGY STAR label is its minimum SEER. This is an energy-efficiency rating, and the higher the number, the less electricity the air conditioner wastes as it cools. To meet the ENERGY STAR program requirements, an air conditioner must have at least 14.5 SEER, easily verifiable through testing.

If you see the ENERGY STAR label on an air conditioner, you can feel confident that it is a safe, beneficial, and non-wasteful unit that will save money for you… provided it’s actually the right unit for your home. This is why you need to have professional assistance, since the ENERGY STAR label isn’t the only important criteria. Let the technician guide you toward the AC that will combine efficiency, environmental friendliness, and effective cooling.

Call our experts in air conditioning replacement in St. Augustine, FL today to get started with an excellent new AC installation for the summer.

Stages of Ductless Air Conditioning Installation

Friday, May 16th, 2014

Ductless mini split heat pumps are becoming an increasingly popular option for home comfort. Because they work without the need for space-consuming ventilation shafts, they permit greater freedom for new construction. They also offer an alternative to inefficient window air conditioning units for older homes that lack ductwork. Since they are heat pumps, they work ideally as air conditioners during the summer and effectively as heaters during the winter.

The work installing a ductless mini split is not as difficult as you might imagine, but it still is a task that should remain in the hands of trained professionals. The stages below are not meant as a guide to help you install ductless air conditioning in St. Augustine, FL (it would require many pages to give you the ability to perform even a poor job) but to give you a sense of the sort of work involved. Rely on experienced professionals for this job: call Climate Masters, where we’ve installed air conditioning of all types since 1988.

Ductless mini split heat pump installation stages

  • First: The installers place wall mounts for the individual blowers in rooms throughout the house, and drill holes through the wall to the outside.
  • Second: The blower units are placed and secured to the mounts, and the installers run lines from blower for electrical power, condensate drainage, and refrigeration circulation. The installers take special caution to make sure there are no leaks that might get between the back of the blower and the wall.
  • Third: The outdoor condenser/evaporator unit is secured in place, and the lines from the blowers are hooked up to it. The technicians make certain that there are no loose connections or breaks in the line through a series of leak checks.
  • Fourth: The outdoor unit is connected to the home’s electrical power.
  • Fifth: The installers perform a full-system check to see that the heat pump works and is matched correctly to the voltage of the home, and that it works in both heating and cooling modes. They will not consider the job finished until they are certain that the new ductless system lives up to your expectations.

We handle all the stages of the life of a ductless system, from planning the installation to yearly maintenance to repairs.

Installing ductless air conditioning in St. Augustine, FL may be the best comfort solution for your home. To find out more, call Climate Masters today and speak to one of our ductless AC specialists.

Common Problems Faced by Commercial Air Conditioning

Friday, May 2nd, 2014

The operation of a commercial air conditioning system is not much different from the systems found inside homes: they use circulating refrigerant, compressors, evaporator and condenser coils, fans, and ductwork. But commercial systems are not only bigger than residential ones, they also undergo a greater amount of work and stress in order to cool down significantly larger spaces and numerous people. This level of continual strain on the system—especially during a heavy and humid Florida summer—will eventually lead to repair issues, no matter how well the system is maintained.

These repairs need commercial HVAC specialists who not only know how to repair the problems of an extensive commercial air conditioner, but also know the local codes that your business must meet. Our team at Climate Masters handles commercial air conditioning in St. Augustine, FL. You can reach them 24 hours a day for the repair service necessary to cool your workplace down and restore comfort to your employees, customers, and clients.

Some problems commercial ACs encounter

  • Zone thermostat errors: Most commercial air conditioning systems are zone systems, where multiple thermostats control different zones inside a workplace. Depending on the size of your business’s workspace, you may have only one or two zones, or you could have more than twenty. A malfunction in any one of the local thermostats will cause uneven heating and a difficult situation to diagnose. Commercial HVAC experts can solve the problem and find out whether you need thermostat work or some other targeted repair.
  • Condenser damage: The most popular type of commercial AC is the rooftop package unit. Having the condenser on the roof saves space, but it exposes the condenser to the elements. If debris enters the condenser unit, it can damage the face, dirty the coils, and spread dust and dirt over the motors—all of which can cause problems with performance or eventually a breakdown. Leave the investigation of rooftop units to professionals.
  • Loss of refrigerant: An enormous amount of refrigerant must course through the lines of a commercial AC system for it to work, and there are numerous places where leaks can occur to allow the refrigerant to escape. Refrigerant loss will not only threaten performance level, it can lead to irreparable damage to the compressor. Commercial specialists will know how to track down the leak locations, seal them, and then recharge the refrigerant to its proper level. Look out for a loss of cooling power as a sign the refrigerant charge is dropping and call for repair technicians immediately.

Neither homeowners nor business owners should delay when it comes to scheduling AC repairs… but the business owner has far more to lose from only an hour of a malfunctioning air conditioning system.

Whenever your company’s comfort is at risk, call Climate Masters for commercial air conditioning in St. Augustine, FL that will resolve the problem.

What Makes Air Conditioning Repair Different from Heat Pump Repair?

Tuesday, April 15th, 2014

If you’ve ever had the operation of a heat pump explained to you, then you’ll know how similar it is to an air conditioner. Essentially, a heat pump works the same as an AC—it cycles chemical refrigerant through an indoor and outdoor set of coils, absorbing heat along one coil and releasing it from the other—but with the major difference that a heat pump can change the direction of its heat exchange. An air conditioning system can only remove heat from indoors and deposit it outdoors; a heat pump can also move heat from outdoors and bring it indoors.

Homeowners are sometimes interested in what makes repairs different between the two systems. We’ll look into this and see where the two stand apart as far as fixing malfunctions.

If you need heat pump or air conditioning repair in St. Augustine, FL, come to the experienced team at Climate Masters, where we’ve worked on both since 1988.

The differences in heat pump and AC repair

For the most part, repairing an air conditioner and a heat pump are similar. The compressors, fans, capacitors, and motors work in the same fashion, and replacing these broken components is identical between the two systems.

One of the big differences is that heat pumps contain a key component that air conditioners lack: a reversing valve. This device is attached to the line exiting the compressor; as refrigerant leaves the compressor, it first enters the reversing valve. Depending on whether the valve is in an excited or relaxed state (whether an electric current is flowing through it or not), the refrigerant will either move first to the outdoor coils or the indoor coils. If the refrigerant goes outdoors first, the heat pump will operate in cooling mode; if the refrigerant goes indoors first, the heat pump will operate in heating mode. Should the reversing valve fail, it must be replaced or the heat pump will remain fixed in one mode. Air conditioners do not need this repair.

Heat pumps can develop frost over either their outdoor or indoor coil due to loss of refrigerant, while an AC will only experience this on its indoor coil. The actual repair work is similar in both cases, however.

Another important repair difference: heat pumps work more per year than ACs. If a heat pump is your only method of heating your home, then it will run in both hot and cold weather. With regular maintenance (and a heat pump does require maintenance twice a year, not once) you shouldn’t have too many repairs, but in general a heat pump will have more repair needs than an AC system.

An important similarity: both need professionals to work on them

No matter what problems afflict your heat pump or air conditioning system, they need a trained technician to fix them. Don’t attempt the work yourself or hand it off to amateurs. For heat pump and air conditioning repair in St. Augustine, FL, you can trust in Climate Masters. We have 24-hour emergency service for your convenience.

What Is Dirty Sock Syndrome?

Tuesday, April 8th, 2014

What is dirty sock syndrome? You may not have heard of it – at least not as it applies to your HVAC system – but it can definitely impact your home. It refers to parts of your air conditioner which smell, and the issues that smell reflects. Air conditioning maintenance in St. Augustine can usually handle dirty sock syndrome, which is a fairly common problem in systems around here. Our climate is made for it, which means it crops up much more often than you’d think.

The professionals at Climate Masters can handle air conditioning maintenance in St. Augustine, which includes dealing with the causes of this smelly syndrome. Call us today. 

Dirty sock syndrome is usually caused by one of two things. The first is the presence of mold, fungus and similar organic compounds within the air conditioner itself. Florida has the humidity to make mold a problem, and when it grows in your air conditioner, it can result in a foul smell that gets blown through you entire house, and this ultimately effects your indoor air quality.  A similar effect can be caused by common household odors, such as pet smells, tobacco smoke and smells from rotting food, which will get circulated throughout the house by your system. In both cases, you’re getting a great big stink every time you try to cool your air.

The solution varies depending on the sort. Molds and bacterial growth are fairly easy to treat. A good maintenance session should clear them out of your system, and regular visits will likely keep them out permanently. In-house odors can be a little trickier, but a service technician can help by making recommendations such as circulating fresh air more regularly, or repositioning certain components such as the laundry or a home gymnasium. More extensive corrections can include installing an exhaust hood in your kitchen, setting up a dehumidifier for your home, and rerouting vents so that they don’t circulate the smells so readily.

Dirty sock syndrome can certainly inspire a few chuckles, but it’s no laughing matter, especially when you’re sitting in the middle of the odor.  If the odor is more than you can stand, then give us a call today. We’ll have it cleaned up and set your air conditioner back on track!

Preparing Your Air Conditioning Unit for the Summer

Friday, March 28th, 2014

We’ve finally reached spring, and although we may still encounter cold days here in St. Augustine during the next month and a half, the summer will leap upon us before we know it with its infamous Florida heat. You’ll switch on your air conditioning, and probably keep it running all the way through September. Make sure that your AC is ready to do the work.

Climate Masters can assist you with preparing your air conditioning in St. Augustine, FL for the heaviest summer conditions. We have helped St. Johns County since 1988 endure the sun and sweat of Florida summer, and with one call to us you’ll be on your way to bolstering your cooling system for the season.

Some Steps of Summer AC Preparation

The most important stage of preparing an air conditioner for long spells of hot weather is a maintenance visit from a professional HVAC technician. Spring is the usual time to have this done, not only because it preps for the summer, but because it’s usually one of the less busy times for technicians. (During the summer, they have numerous emergency calls to attend to.) Air conditioner maintenance checks will inspect the AC to see that all its systems are operating without impending repair needs. The technician will check that you have the correct level of refrigerant, all electrical connections are tight, and no excess dust or dirt is clogging any of the components.

Maintenance will also catch malfunctions that you may not have noticed yet. This is the next important stage of AC preparation: having any repair needs—even small ones—taken care of right away. You do not want to begin the summer with an air conditioner running with a fault that will impair efficiency and may lead to a break down during one of the hottest days of the season.

Finally, make sure to have your air filter changed out so you’ll have a unit free from any contamination that might either lead to debris entering the AC cabinet of a restriction on airflow. For the rest of the summer, change the filter once a month to maintain the best performance from your cooling system.

Start With Maintenance Now!

Call Climate Masters today and talk to us about our maintenance program. We offer two visits per year, one in the spring for your AC and one in the fall for your heater. A friendly technician can give you more details about how we can ready your air conditioning in St. Augustine, FL for the summer.

Why Winter Is a Good Time to Get Air Conditioning Maintenance

Friday, November 8th, 2013

We’re always concerned about air conditioning in St. Augustine, where temperatures run high and the humidity is quite beastly. That can make it tricky to schedule any maintenance or repair, since we need our air conditioners to keep our homes comfortable in the face of outdoor heat. At the same time, however, it’s important to schedule regular maintenance sessions for your HVAC system, in order to keep it functioning as efficiently as possible. It’s usually best to plan for such things in the winter months: from around Thanksgiving until the end of March.

Here’s why winter is a good time to get air conditioning maintenance.

  • You’ll have less need of the unit. We get our share of warm days in the winter – certainly more than cities further north – but they’re comparatively few and far between. Most temperatures average in the high 50s, which is enough to do without an air conditioner for the time it takes to perform maintenance on it. Winter tends to be drier than summer too, which means the repairman won’t have to deal with rain while trying to do his job.
  • Less demand. When an air conditioning unit breaks down in the summertime, service technicians need to deal with it immediately lest their clients’ homes turn into furnaces. That puts a high demand on their services, which means you may need to wait for a while before a technician can schedule a maintenance session for you. Demand is much less high in the winter, and you can likely find service technician much more readily.
  • Summertime takes its toll. With your air conditioner running all day every day during the summer months, it’s bound to generate a lot of wear and tear. A maintenance session in the winter can take stock of all that, and plan to address it in a timely fashion well before next summer rolls around. This helps extend the air conditioner’s lifespan and reduce the risk of more extensive repairs.

If you know why winter is a good time to get air conditioning maintenance, call upon Climate Masters for help. We can repair and maintain all kinds of air conditioning in St. Augustine, so don’t hesitate to contact us today!

How Long Does It Take to Install An Air Conditioner?

Thursday, October 17th, 2013

Here in St. Augustine, air conditioning installation can take on an air of urgency. Our warm and humid summers can be unbearable without a reliable means of cooling the air, and even the winters can be warm enough to merit the use of a reliable air conditioning system. In that environment, it’s very reasonable to ask “how long does it take to install an air conditioner?” The answer of course, is that it depends on the specific circumstances involved and the nature of the unit in question.

In most cases, installation can take place within a day or so. This assumes that the weather is clear, and that no major alterations need to be made to your home. The technician will arrive, prepare for work by laying coverings over your floors and furnishings, remove your existing unit, install the new one and ensure that it’s functioning before declaring victory. A professional will explain all of the steps to you, then undertake them with courtesy and professionalism, making sure that everything is in its proper place.

That rough timetable assumes that you’re replacing an existing unit with a similar unit, or that your installation won’t involve any additional work. Sometimes, however, it does. For example, you may need to have ductwork installed in a home that doesn’t currently feature any, or you want to install a geothermal system and need to provide time to dig trenches for the tubing. In that case, it may take a longer period of time than a simpler operation.

No matter what the specifics, however, you should always get an estimate from your service technician about the price involved and the time it will take. Once you have a schedule in hand, you can plan for the installation with greater confidence, and let the technician work with a better idea of what exactly is going to be involved.

In St. Augustine, air conditioning installation service is the purveyance of Climate Masters. We can tell you how long it takes to install an air conditioner, and provide an estimate as to the costs before we begin.
