Air Conditioning Installation

How Do Air Conditioners Work?

An air conditioner cleans, circulates, cools and dehumidifies (removes undesirable moisture from) indoor air. A filter cleans the air by trapping dust and other small particles. An air handler (blower built into the system) circulates it, while the cooling and dehumidifying are accomplished by a process called refrigeration.


Refrigeration cools a home by transferring heat inside a home to the outdoors. All central air conditioners employ two main units in this process – the indoor unit and the condensing unit.

The Indoor Unit

This unit removes undesirable indoor warmth and humidity. It includes the filter, the air handler and the evaporator coil. The air handler blows filtered air through the evaporator coil. The evaporator coil is kept cold by the circulation of a substance called a refrigerant. Air that travels across the evaporator coil gives up heat (the colder coil absorbs it) and humidity (moisture condenses upon contact with the cold surface of the coil). The cooler, drier air that continues through the air ducts is vented throughout your home to maintain your desired comfort level. Depending on the structure of your home, the ductwork may be above the ceiling or below the floor.

The Condensing Unit

Outdoors, at the condensing unit, an air conditioner releases the heat that was captured indoors. The same refrigerant that absorbed the heat indoors at low pressure is now pressurized by the compressor and is circulated through another coil, the condensing coil. In the condensing coil, under high pressure, the refrigerant releases its heat very quickly, making the coil itself hot. A fan blows across the coil, cooling its temperature down and transferring the heat to the outside air.

The Thermostat

Whether you heat your office with gas or electricity, a wall thermostat will be installed. This measures room temperature and turns the central heating system off or on as the temperature rises or falls to designated levels. Careful location of the thermostat is an essential consideration in maintaining maximum comfort levels in your business.

I am new homeowner and had never got a heater inspection/tune-up... I scheduled one with Precision and had a great experience. My technician Steve was timely, professional, (funny), and honest. He showed me a few ways to increase the life of my system while also improving the quality of my air and lowering my utility bill. I recommend Precision Air for sure.

I hired these guys to service my old boiler and radiator heating system. The unit was made in 1987 so I was expecting to have to get a new unit. While it does need to be replaced eventually I was happy that they didn't make me feel like I had to. They just serviced it and gave me a recommendation for a new one. They seem like honest guys. Thanks.

You installed new high efficient gas tank-less heater this winter and I wanted to wait to give a full review. Everything with the installation was very easy from Tim making the appointment showing up on time and being very helpful through our decision process. He did not try to get us to buy with all kind of specials like some of the other companies. One large company would not leave my home unless we signed that day. We had to throw them out all they were concerned with was selling us a heater! When Lou the installation manager came out to do the materials list he was polite and attentive to our needs. The men did not make do or improvise because they had all the right parts and it looks much better than my neighbors who used another local company. Greg did a great install on our oil to gas conversion. I could not believe that small wall hung unit would heat our home. Well it not only heat our home and hot water it reduced our costs a whole bunch! We normally used 900 gallons of oil at an average cost of 3.75 for yearly budget of 3400. This winter we only spent just over $600. Thank you Precision Air for guiding us on our new tank-less heating system and being so professional.
