How often should I change my Filter?

We recommend you change your filter once every 30 days. If you smoke in your house, have inside pets, a large amount of traffic in the house, check your filter once a week. Your outside environment should be considered as well. Dusty or high pollution areas have a huge impact on your filter as well.

Your filter costs a few dollars and can save you huge headaches and moneydown the road. Problems include your blower motor working harder, shortening its' life or worse, your evaporator coil could become your filter. Eventually your system will ice over resulting in a maintenance call.

Q.

A.

What could cause my Air Conditioner to blow cool but not cold air and run constantly during the hot Summer months?

Your condenser or evaporator coils may be dirty. This would cause inadequate air flow around the condenser.

There may be a refrigerant leak in you’re A/C system.

There could be a leak in your supply or return duct system.

Your breaker to your condenser may be tripped.

Your outside unit may be clogged with dirt and debris.

Q.

A.

What kind of Freon does a home air conditioner use?

Most home systems use R-22 refrigerant, although, R-410a, also known as PURON is becoming increasingly popular, though. There usually is a designation on the tag near the serial number.

Note: Releasing refrigerant into the atmosphere is illegal. Only allow a licensed HVAC contractor such as Edmond Air Conditioning, Heating & Plumbing service your unit!

Q.

A.

What is 'SEER'?

SEER is a measure of seasonal or annual efficiency of a central air conditioner or air conditioning heat pump. SEER takes into account the variations in temperature that can occur within a season and is the average number of Btu of cooling delivered for every watt-hour of electricity used by the heat pump over a cooling season.

Q.

A.

Will a Programmable Thermostat reduce my Heating and Cooling energy consumption?

Yes, programmable thermostats can reduce the energy used for air conditioning or heating by 5 to 30%. Programmable thermostats save money by turning the air conditioner to a higher setting (or heater to a lower setting) when no one is present in the house, or in the evenings when it is cooler.

Q.

A.

What is the most important thing to consider when buying a new air conditioner?

When it's time for a new replacement, choosing one of the correct size (heating and/or cooling output) is critical to getting the best efficiency, comfort, and lowest maintenance and operating costs over the life of the new system.

The most common sizing mistake is in over-sizing. This not only makes the new system cost more to install, but also forces it to operate inefficiently, break down more often, and cost more to operate. Oversized heating equipment also often creates uncomfortable and large temperature swings in the house. Oversized air conditioners (and heat pumps) do not run long enough to dehumidify the air, which results in the "clammy" feeling and unhealthy mold growth in many air-conditioned houses.

It is the installer/contractor's job to perform the correct sizing calculation for the building. However, some national surveys have determined that well over half of all HVAC contractors do not size heating and cooling systems correctly.

Q.

A.

How do you know if your cooling system can be repaired or if it is time to replace it?

Energystar.gov provides a basic checklist to help you determine if it's time to replace your existing heating/cooling system.

Consider replacing if:

Your heat pump or air conditioner is more than 10 years old Your furnace or boiler is more than 15 years old Your equipment needs frequent repairs and your energy bills are going up Some rooms in your home are too hot or too cold No one is home for long periods of the day and you do not have a programmable thermostat Your home has humidity problems Your home has excessive dust Your heating or cooling system is noisy
