FAQ

 

 

 
 
  Q. Do I need service if my air conditioner seems to be operating fine?
A. Yes. Simply because there is cool air blowing from your house air ducts does not mean you're getting all the cooling air conditioned comfort you're paying for.

Q. What kinds of things can cause my air conditioner to operate inefficiently?
A. Improper refrigerant charge and air flow are the two biggest culprits. Too much or too little refrigerant can cause your air conditioner to overwork. The same is true if the air flow across the inside coil is low. 

One or more of the following symptoms which may require your AC to be serviced

  • Your Air Conditioner Runs Too Long
  • Your Air Conditioner Runs All the Time
  • Your Utility Bills Seem High
  • The Indoor Humidity is Just As High or Higher than the Outdoor Humidity
  • Some Rooms are Hot while Other Rooms are Cool
  • Your House Never Seems to be Comfortably Cool Enough
  • You've had Refrigerant Added More than Once in the Past 5 Years
  • There is Too Little Air Flow from the Floor or Ceiling Registers
  • Extremely Cold Air is Blowing from the Registers
  • The Air Conditioner Keeps Shutting Off When the House is Hot.
  • The Air Conditioner Has Not Been Serviced For More Than Two Years.

  • How often do I change my furnace filter?

    A dirty air filter can cause big problems on a furnace heating exchanger and furnace blower motor. A heat exchanger is like your car engine if you don’t have enough air (antifreeze) removing heat off the surface it runs too hot in the winter. If you have air conditioning a dirty filter can cause the “A” coil that circulates freon located on top of the furnace to freeze in the summer. A dirty air filter can also cause the furnace blower motor to pull more electricity and over heat as well. My advice would be to change the furnace filter at least once every 4 to 6 weeks during heating season and for air conditioning once a month.

    What kind of filter do you recommend?

    In the winter you can use any kind for heat EZ flow, high efficiency or pleated (accordion type) In the summer for air conditioning I only recommend EZ flow or flat filters. The “A” coil is very easy to frost and needs as much air as the blower motor can push, a high efficiency or pleated filter will obstruct the air flow and cause frosting and eventually freeze in a matter of days to were you have solid block of ice sitting on your furnace.

    What Do I do if the coil freezes up?

    If in the summertime you notice water on the floor around the furnace and when the air conditioning is on there is no air coming out of the vents you most likely have a frozen coil. If you filter is the wrong kind or dirty replace it. Then go to the thermostat and switch cool to off and auto to fan. What this does is run your fan continually without the air conditioning and allows the “A” coil to thaw out (it usually takes 24 hrs to thaw)

    Is it a good Idea to run the fan on thermostat all the time to circulate air?

    I recommend for homes in summertime to run the fan all the time to circulate the air conditioned air this will keep a more constant temp throughout the house. With homes with vents on the floor it helps to keep the air from stratification (a blanket of hot air on the ceiling and cold air on the floor). Ceiling fans are important too in summer turn them clockwise in winter counter clockwise. You air conditioning will come on and off by the thermostat but the fan will run constant.

    Why did my furnace blower motor go out in just a couple years from purchase?

    If you have both a heating and air conditioning system and the thermostat is set on auto your blower motor turns on and off every time it calls for heat or cool.
    The amount of strain on the motor windings is much higher than if the fan is allowed to just run continually. Ex: If a light bulb is turned on and off continually it will burnout faster than if it was just left on.
