What size Heating Ventilation and Air Conditioning unit should I have for my home?

It depends on the square footage and available duct work in the home. Contact us at (847) 719-2665for a free estimate with our comfort consultant.

How is the efficiency of heating and cooling equipment measured? 

It is measured in SEERS. The higher the SEER rating, the larger the coil is, thus more efficient (temperature difference between entering air vs. discharge air). Gas Furnaces are measured in AFUE.

How much does a new replacement system cost? 

It depends on the size of equipment needed and what filtration system or zoning system you would like. Contact us at (847) 719-2665 for more information and a specific estimate.

What are the advantages of a programmable thermostat?
