Many of the phone calls we get boil down to cleanliness. The filter of of these systems can wreak havoc if it is clogged. The first thing you should do is unplug the furnace then clean the filtration system (filter). Wait a little while then make sure the thermostat is off and plug it back in. Do not call for heat or cooling with the stat while unplugged. Turn the stat to the desired setting and make sure it works. If that didn't solve the issue click on the "start learning" button and find the issue if possible. You can also email or call us. Good luck and be patient!

A clean filtration system? More important then you think!

There are many important parts involved with heating, cooling & air conditioning your home. None much more important then your filter! It can raise your utility bill, lower the life expectancy of the equipment and leave you with no heat on a cold winter night. Left unchecked it clogs and wreaks havoc on your system. 75% of all phone calls we get are clogged filter related. Fortunately for our customers, we walk them through the issue most of the time right over the phone. We have an android phone app that you can download, it will remind you on your cell phone to check your filter. You can get the app HERE!!!
