• Do water heaters need maintenance?

  The short answer, yes. Many hot water tanks have to be replaced due to the simple fact they weren't maintained properly. As water is pumped into the unit, any impurities such as dirt, sediment and various minerals settles in the bottom of the unit. Over time these impurities build up and eventually affect performance. The system will be forced to  work harder due to a lowered efficiency and if left unchecked, the deposits will lead to rust, corrosion, and eventually, total failure.

• Does my house need surge protection for the HVAC system?

  Since manufacturers started using printed circuit boards (PCB) to control the unit, they are susceptible to the same risk of damage by lightning as your computer or television. It's to exhaustive to list each manufacturer and when they started using PCB's in their units, but we can easily check on your next routine visit. It's far easier to simply install a surge suppressor strip with a joule rating of no less than 480 and a low voltage pass through. A good voltage pass through is 330. Be sure and stay away from any units over 500 volts.

• How do I check for a dirty evaporator coil?

  First let us remind you that we do this as part of our maintenance package.

  A good unit should have the capacity to cool 20 - 25 degrees F. Many things cause a system to stop cooling properly, but dirt is the most common problem. Other reasons include improper freon levels or  the house doesn't have balanced airflow to the rooms. There are other reasons that could indicate a more severe problem with the unit. To be sure, have us come out and check the unit.

• How do tankless water heaters work?

  Instead of housing water in a tank that is then heated to a target temperature,  tankless water heaters are able to heat the water as it passes through, alleviating the chance that you'll run out of heated water. Gas tankless water heaters use high-powered burners to quickly heat water as it runs through a heat exchanger. In consumer reports tests, average gas models tend to be 22 percent more energy efficient on average than the gas-fired storage-tank models they were tested against.

• How do you size the air conditioner for the house?

  In order to properly size a unit, one of our qualified service techs will need to inspect your house. They will take into account construction, size, quality and quantity of windows as well as your living habits to give you a custom sized unit.

  An oversized unit can be as detrimental as an undersized one. Oversized units tend to run in shorter bursts that lead to less humidity being removed from the air making it feel warmer inside. They will also start and stop more often leading to higher electric bills. To learn more, call us to schedule a consultation.

• What is a heat pump?

  Like your refrigerator, heat pumps use electricity to move heat from a cool space into a warm, making the cool space cooler and the warm space warmer. Heat pumps can trim the amount of electricity by as much as 30-40% versus traditional units. Unless they are used in conjunction with geothermal (ground source or water source) systems, they can lose efficiency around freezing temperatures. If your house is all electric, you might just want to consult with us about this possibility to see if its right for you. As of September 2011, the federal government and Edmond electric are still offering incentives to switch to electric heat pumps.

• Why are rating numbers important?

  Rating numbers indicate the efficiency of heating and air conditioning equipment and are directly related to the amount of energy a specific model uses. The higher the rating, the more efficient the product, and the lower your heating and cooling bills can be. The federal government establishes rating guidelines and sets minimum efficiency levels. For cooling, the rating is SEER (Seasonal Energy Efficiency Ratio). For heat pumps, the rating is HSPF (Heating Seasonal Performance Factor). Gas furnaces are rated with AFUE (Annual Fuel Utilization Efficiency). From American Standard.
