What is Geothermal heating and cooling and how does it work?
Proper servicing of your heating system can prevent carbon monoxide poisoning. Learn more about this potentially dangerous hazard.
What services need to be performed for preventive maintenance on my heating and air conditioning equipment, and how often should this maintenance be performed?
We recommend preventive maintenance before the winter heating season and before the summer cooling season. Many of our customers prefer our maintenance service agreements that may include reduced rates on labor and parts and provide priority response. Service/maintenance agreements may include cleaning indoor and outdoor coils, tightening electrical connections, checking supply voltage and operating current, checking refrigerant charge, measuring temperature differential at supply and return registers, cleaning blower wheel and motor, inspecting and adjusting burner, checking heat exchangers, cleaning drain lines and pan, checking ductwork for leaks and insulation, and checking thermostat.
I need a new outdoor unit, but my indoor unit works fine. What are the advantages of replacing my whole system at the same time?
We recommend that your replace the indoor coil or air handler when replacing the outdoor unit. Both of these components are integral to the closed refrigerant loop and together determine the capacity and efficiency of your system. If you do not replace the indoor unit, there will be no test data available for the new combination to establish the expected capacity or efficiency of your system. Also, the indoor system may be partially blocked by particles that will decrease efficiency, and you may be faced in the near future with replacing the indoor unit after it fails and having to pay to have the closed refrigerant system opened again. It would be expensive and be another opportunity for contamination. You end up paying more. If your whole system is replaced, you will be less likely to need service in the near future.
Should I cover my outdoor unit in the winter?
Covering the unit is not necessary. Air conditioners are manufactured to withstand all possible climate changes. In fact, rain helps keep your unit clean. Of course, because heat pumps run all year long, they should never be covered.
How close to the outdoor unit should I plant shrubs or flowers?
Manufacturers generally agree that plants should not be closer than 18 inches. Air conditioners need intake and exhaust air to operate efficiently. If air cannot circulate, the unit could build up heat and require service.
What are the average life expectancies for heating and air conditioning equipment?
The average expected life of an air conditioner is approximately 15 years. The average expected life of a heat pump is approximately 10 to 12 years, since it operates year round. The average expected life of a gas furnace or air handler is approximately 18 years. Units in corrosive environments, such as, but not limited to coastal installations, will tend to have shorter lives.
Is there any advantage to setting my thermostat fan to "ON" so the fan runs constantly?
Yes, there are a couple. The first is that you get constant filtering of the air in your home. The second is that because the air is moving, you have a more even temperature throughout
