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 derived 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.
Wilson's Refrigeration and A/C Service has been providing me with excellent maintenance on my home HVAC for over 10 years, extending the life of my unit considerably. Their techs are knowledgeable, responsive, skilled, and pleasant to deal with. They are available 24/7 and prompt when an occasional emergency occurs, especially after hours. Most recently, after thorough consultation with Jimmy, we elected to replace our aging unit with a carefully selected top of the line hybrid HVAC (electric and gas). I couldn't be more pleased with our new unit and their continued maintenance. They are good people to deal with.
