Do You Think Your Air Conditioner May Have a Refrigerant Leak?

Monday, November 2nd, 2015

An electro-mechanical system like your air conditioner can develop a number of problems. Among the more common problems the cooling professionals from Climate Masters see are refrigerant leaks. The thing to keep in mind about these kinds of leaks is that they aren’t always visible. This is because refrigerant runs throughout your entire AC system as it completes a cooling cycle, so a leak can develop anywhere the refrigerant is. However, there are some fairly distinct signs your AC will give if a leak has developed:

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.

How Can Dust and Dirt Cause a Need for Air Conditioning Repairs?

Monday, September 30th, 2013

After a long, hot summer in Florida, your air conditioning system might have accumulated a bit of dust and dirt. Even if you’ve regularly changed your AC’s air filter (something you should do once a month during the peak season), some debris can slip into your ducts or into the air conditioner cabinets. Aside from decreasing the quality of air in your home, an accumulation of dust and dirt can cause the need for professional repairs. For quality air conditioning repair, St. Augustine, FL, residents can turn to the experts at Climate Masters. If dirt is giving your AC grief, we can offer a solution. Contact us today for an appointment.

The ways dust and dirt can cause the need for repairs include:

Dirty condenser or evaporator coils: The two coils in your air conditioning system—the condenser outside and the evaporator inside—are vital for the heat exchange that cools your home. If they become dirty, they will lose their ability to absorb and release heat. You may experience a rise in temperature, and your air conditioner will overwork itself to compensate. Cleaning the coils is a difficult process that requires cutting and sealing the refrigerant line, and should be left to trained technicians.

Inefficient blower motor: The blower motor that distributes air and helps with heat absorption will start to work at lower efficiency if it becomes too dirty. This reduces airflow and could increase your electrical usage by 50%. The motor must be cleaned, or perhaps replaced if the problem has persisted too long.

Clogged air filter: The air filter does the job of trapping dust and dirt and any other airborne contaminants from getting into the interior components of your AC. Without regular changing, an excessively clogged filter will require professional attention because it will impede the flow of air and heighten the risk of extreme damage to motors, fans, and the compressor.

One of the best ways to keep your air conditioner free from dust and dirt is to schedule regular maintenance with an experienced HVAC company. Climate Masters offers an excellent maintenance program that gives you two annual check-ups, one for your AC and one for your heater. We aim to give you complete customer satisfaction, so if you want maintenance or air conditioning repair in St. Augustine, FL, make us your first choice.
