Frequently Asked Questions (FAQs)
 

What is the average life of an Indoor Comfort System?
First, check out what EnergyStar says. The lifespan is different for furnaces, boilers, heat pumps, and air conditioners. Without yearly maintenance, the life expectancy decreases, and efficiency drops.
 
What would a new heating and cooling system cost?
There is no easy answer. We would need to calculate the heating and cooling load and determine if ductwork is sufficient (over 80% of homes in southern Illinois have insufficient ductwork). Then we would balance the system's efficiency level with your budget. Estimates are free, so give us a call. 618-694-7699
 
Should I set my thermostat fan switch to "auto" or "on" when running my AC?
You should use the “auto” setting so that the fan runs only when needed to maintain the set temperature, especially if you have an old PSC blower motor which wastes electricity. This also prevents reintroducing humidity back into the living space. Once your AC turns off, the blower fan may evaporate condensation off of the evaporator coil. If you desire a more consistent temperature, give us a call. It may be time to upgrade to a higher efficiency modulating system.
 
How often do I need routine maintenance performed?
On average, you should have your system serviced twice a year, once in the cooling season and once in the heating season. Routine preventative service will extend the life of your unit. See what EnergyStar says about routine maintenance. Depending on the environment your commercial system is exposed to will determine the need for tune-ups and cleaning. Give us a call for a commercial maintenance inspection. 618-694-7699
