Air Conditioning Tune Up Time Is Here

Spring is here, is your Air Conditioner ready?

Spring is in the air, and soon it will be time for homeowners & businesses all over Bucks and Montgomery County to turn on their Air Conditioners. With the warmer weather we had had in recent years it’s a good bet that it will get warm quickly and units will run more often, or possibly non-stop for several months.

A Spring Air Conditioning Tune Up is a valuable and often times money saving expenditure well worth investing in. If you had brand new equipment installed in the latter part of the last Summer, then you don’t need a tune up but a safety inspection is a good idea.

In the Spring it's obviously not as hot outside as it will be in July, August, and September. Homeowners turn on the system to test it, cool air comes out and they think everything is working fine, while the truth of the matter is that there can be serious problems that will, if left undiagnosed and unresolved - lead to much more expensive repairs having to be made later on in the Summer when you REALLY need your home's air conditioning working at peak performance.  In a nutshell, this is the reason why it is very worthwhile to either have an Apple Comfort One Hour Heating and Air Conditioning Technician inspect and tune up your Air Conditioner(s).

Air Conditioning 101 - The Basics

Is your home being cooled properly?

Here at Apple Comfort's One Hour Heating and Air Conditioning we have helped thousands of customers over the years who need help with air conditioner repairs or installation. We understand the importance of feeling comfortable in your home’s climate. Air conditioning is a process that controls the filtration, air movement, temperature and humidity of a given environment. Air conditioning is always associated with the cooling and the dehumidification process of air, and is therefore identified with refrigeration equipment. A residential central air conditioning system keeps your entire home cool in the warmer months, while it helps lower indoor humidity levels. Air conditioners can be centralized with ductwork to carry the cooled air to various rooms or individual units that cool specific areas.

How Does Air Conditioning Work?

Most people think that air conditioners lower the temperature in their homes by pumping cool air in. The actual process removes warm air from your house and cycles it back in as cooler air. This cycle continues until your thermostat reaches the desired pre-set temperature.

System elements include a compressor, a fan, condenser coil, evaporator coil, and a refrigerant. The unit extracts heat from indoor air and transfers it outside, leaving the cooled indoor air to be re-circulated.

An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant to provide cooling. The mechanics of the refrigerant evaporation cycle are the same in a refrigerator as in an air conditioner. A compressor compresses cool refrigerant, causing it to become hot, high-pressure gas. This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid. The liquid then runs through an expansion valve, and in the process it evaporates to become cold, low-pressure gas. This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the home.

Three elements which make up a split central air conditioning system, are:

  • An outdoor condensing unit
  • A matching indoor air handler
  • Ductwork to transfer the cooled air throughout the home

Air Handler

I've got a rattle coming from my heating and air system.

Air handlers are an important component to any HVAC system. Usually, an air handler is a large metal box containing a blower, heating and/or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to ductwork that distributes the conditioned air through the home, and returns it to the air handler. Sometimes air handlers discharge and admit air directly to and from the space served, without necessary ductwork.

Air handlers typically are comprised of:

Blower/fan – usually located in a large squirrel cage blower driven by an electric motor to move the air. The blower may operate at a single speed, offer a variety of pre-set speeds, or be driven by a variable drive so as to allow a wide range of air flow rates.

Heating and/or cooling elements - depending on the location and the application, air handlers may need to provide heating, or cooling, or both to change the supply air temperature.

Filters – air filters are almost always present and needed in order to provide clean dust-free air to the home interior.

Humidifier - is often necessary in colder climates where continuous heating will make the air drier, resulting in uncomfortable air quality and increased static electricity.

Mixing chamber - to maintain indoor air quality, some air handlers commonly allow the use of outside air into, and the exhausting of air from the home. A mixing chamber is used with dampers to control the ratio between the return, outside, and exhaust air.

Controls - are necessary to regulate every aspect of an air handler, such as: flow rate of air, supply air temperature, mixed air temperature, humidity, air quality. Common control components include temperature sensors, humidity sensors, sail switches, actuators, motors and controllers.

Vibration isolators - since blowers in an air handler can create substantial vibration, are normally inserted into the duct immediately before and after the air handler and often also between the fan compartment and the rest of the air handler.

An air handler is usually located in the garage, a closet, or in the attic unless it is part of a package unit, then the air handler is incorporated in the system. The air handler can be an up flow air handler, down flow air handler, or horizontal flow air handling unit.

Quick Tips

Tip Ten

Lubricate the condenser fan motor once a year if it has oil ports. (They're usually plugged with rubber or metal caps). Use non-detergent lightweight SAE 20 oil and add no more than 10 drops per port.
