June 7th 2026 my AC went out and when I made the call to mechanical Hvac someone answer the phone and less then 15 minutes they were trying to get someone to come check on the unit. Less than a hour someone were heading to the house and fixed the problem on a Sunday morning. I truly appreciated that fast service on one of the hottest days of the year.

This was for the annual maintenance contract renewal plus some Freon. The maintenance program provides for two HVAC checkups per year. Doing this gives me peace of mind that my HVAC system is running efficiently and effectively all year. Mechanical HVAC has been my provider since 2020 and I recommend them. They are very qualified and trustworthy.

Bailey and Corey removed an old HVAC system and installed a new one. They arrived on time and were very professional and courteous. They have great technical skills and are knowledgeable with all aspects of the system. Both of them are effective communicators and answered all of our questions. They left the work area clean and removed all outdated equipment. I highly recommend them.
