"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."

"Rather than just replace an ailing system, they worked with me to make sure my home could be as comfortable as possible. They clearly have a lot of expertise in HVAC and venting systems. So glad I hired them!"

"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."
