Reviews
We are very happy with our experience with Com24 Heating and Air Conditioning. We needed advice for a failing air conditioning system that had been installed but was not adequate for our home. Comp24 promptly came out, reviewed our entire system and gave us a very informative way to solve our problem. Their estimate was put in writing and received very quickly. Communication with them was always promptly returned and helpful.
The day of installation was prompt, very professional and thorough. Once they were done, they walked us thru the work completed and how everything worked.
I highly recommend them and we will be continuing using them for our HVAC needs.
We were having humidity issues in our home and contacted Com24 to come out for an inspection, turns out we needed a whole house humidifier. Zeke and Jay had the part delivered early in the morning and we're here at the scheduled time that day for the installation. Both gentleman were knowledgable, skilled, polite, courteous and cleaned up after themselves.
We are very happy with our humidifier and are no longer experiencing issues. THANK YOU Com24 for the excellent service!
