"Will and Eddie from CHEEKY Heating and Air came out today to install the 5” filter replacement on our Air Handler. Additionally, he and co-tech Eddie installed an additional return air vent and line to our overall system. Will seemed to be thorough and knowledgeable of all aspects regarding the installation. During the installation and completion of the work, Will kept us informed about the install progress and made sure there was “no mess left behind” when work was done. Thanks Will and CHEEKY for your trusted HVAC installation."

"My husband and I have used Moncrief for nearly 30 years -- ever since we bought this house. The prior owner used Moncrief and recommended them. Over the years we have had this company perform all service/maintenance work on our HVAC system. They are not cheap, but they do good work and are very trustworthy.
