Things to KNOW

Let us empower you with HVAC knowledge and give you options.

cheaper is not better
Change your filter

It's our goal to empower our customers with knowledge and give them options to make wise decisions for their family and home when it comes to their heating and cooling needs. Home owners tell us they did not KNOW, for example that brand is not as important as the installation and maintenance of their equipment. That changing the filter regularly can extend the life of their air conditioner and furnace, or that a permit is needed for installs or replacements of HVAC equipment. We pull permits and have all HVAC installs inspected by the local municipality. You need to KNOW that bigger is not always better and that cheaper is not always the best way to go. If you are looking for the cheapest equipment installation or services DON'T call us, we do it right the first time. There's always someone willing to do it cheaper. We'll be happy to answer any questions you may have 614-678-6344
