FAQ's
The SEER (seasonal energy efficiency ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 21.
Each split system cooling unit has a nominal SEER rating. This rating can be increased with the upgrade of the same series indoor unit. The SEER rating of a system is based on the combination of equipment installed in the home. The outdoor equipment (heat pump or air conditioner), as well as the indoor equipment (evaporator coil and furnace, or air handler), play a vital role in the total rating.
Your heating and cooling systems work incredibly hard to perform their functions for your home everyday. The constant stopping, starting and continual operation can wear down any machine if the proper care and maintenance is delayed. However, by performing regular maintenance, you can maximize the lifecycle of your heating or cooling unit and guard against many common equipment failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts. You should have maintenance completed on your system regularly to ensure maximum efficiency and prevent possible problems that may occur in the near future.
Heat pumps and air conditioners require a professional tune-up twice a year; in the spring and fall. Inspections on boiler and furnace systems should include ductwork, pipes, dampers, valves, the chimney, registers, radiators, pumps, blowers, fuel lines, oil tank and every part of the actual furnace and boiler. Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils, and refrigerant lines.
Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.

Call them because our heat wasn’t working, they were at the door right when they said they would be. Figured out the problem replaced the part, and come to find out it was under warranty. Could have charged me for the part I wouldn’t have ever. If there’s ever anything heating & cooling problems around my house I guarantee I’m calling them.
