Why Is There Frost on My Air Conditioner?

Monday, April 27th, 2015

Frost and frozen condensate build-up rank among the most common air conditioning problems reported in Orlando, FL, which can seem counter-intuitive on the surface. “Doesn’t frost build-up mean that it’s really cold?” When you add Orlando’s famous humidity to the mix – creating condensation on AC units that can easily frost over – it seems almost like a natural state of affairs. In truth, however, frost on your air conditioner represents a serious problem, and the longer you let it go, the worse it gets. The answer to the question “why is their frost on my air conditioner?” explains a great deal. (more…)

Reasons to Consider Ductless Air Conditioning

Monday, April 6th, 2015

Are you building a new home, or need to replace an aging, outdated air conditioning system? You may want to consider the installation of a ductless AC. Ductless air conditioning is fast becoming a top choice for whole home air conditioning for several reasons, but excellent installation is the key. The air conditioning experts at Certified Air Systems, Inc., have been helping customers in the Orlando, FL, area with their air conditioning needs for over 20 years, including installation. So why should you consider a ductless air conditioner for your home? Let’s take a look.

Benefits of Ductless Air Conditioning

Ductless air conditioning systems work by delivering air through indoor blowers that are supported by a single outdoor unit. The outdoor unit holds the compressor and condenser and can support up to 4 indoor blowers at a time. Each indoor blower operates separately, which brings us to our first great benefit: customized cooling. Indoor blowers operate individually, allowing you to cool an area just as you want to. You can also cool only the areas that you need to, which is a second benefit of a ductless AC system: better energy efficiency. When you cool only the areas that need it, you use less energy, thereby reducing your overall energy use. You also reduce the overall usage of your AC, which brings us to our third benefit: less stress on the system. A system that isn’t stressed works optimally, providing you with the comfort you need.

The lack of ductwork also provides some benefits. First, you don’t have to worry as much about air loss from faulty ductwork, which can greatly compromise your energy efficiency levels; second, you don’t have to worry about adding expensive ductwork to your home and lastly, expansion and installation can be easier with a ducted system because there is no ductwork to contend with.

Installing a new air conditioner can be a great opportunity to use a different whole house AC system that may fit your need better. Ready for a new AC? Call us today and schedule an appointment!

How Is a Heat Pump Different from an Air Conditioner?

Friday, April 3rd, 2015

Heat pumps and air conditioners are, in most important ways, the same type of appliance. They operate on the principle of heat exchange, the shifting of heat from one location to another, and both use the same types of refrigerant to move heat between sets of cabinets. Most of their internal components are identical, and when a heat pump is in cooling mode, there is little outward difference between it and an air conditioner.

Of course, there is an important difference between the two: a heat pump can work as both a heating and cooling system. In this post, we’ll look at a few of the internal differences between the two systems that allow a heat pump to perform two functions.

For more information regarding heat pumps, or to schedule service for the heat pump that keeps your home comfortable around the year, call on Certified Air Systems, Inc. We provide installation, repair, and maintenance for heat pumps in Orlando, FL.

The Heat Pump Difference

The key difference in a heat pump is a component called the reversing valve. This valve is attached to the refrigerant line near where it exits from the compressor, and it is what allows the heat pump to change between heating and cooling mode. When a slider in the valve moves, it reverses the direction that refrigerant travels when it exits the compressor. If the valve moves the refrigerant to the outdoor coils first, the unit is in cooling mode. If it moves the refrigerant to the indoor coils first, the unit is in heating mode.

Another difference is that a heat pump uses less refrigerant when in heating mode. A component called the suction line accumulator, positioned between the compressor and the reversing valve, siphons away the extra refrigerant until it is needed again, and helps prevent this refrigerant from flowing back into the compressor. A crankcase heater on the compressor takes care of evaporating any liquid refrigerant that might enter the compressor from the wrong direction.

Finally, heat pumps need to have two sets of condensate pans and drains, one for the outdoor unit and one for the indoor unit. An air conditioner only requires one set, since evaporation and dripping water moisture only occurs in the indoor unit.
