I called Donovan Heating and Air for a quote to install a NEMA 14-50 charging EV outlet. Parker and Jesse arrived for the estimate less than two hours from the first phone call. Both Jesse and Parker were professional, punctual and very pleasant. They completed the job in less than an hour and I have a nice, clean looking 240v outlet. I would definitely use their services again.

Donovan's has saved our company tens of thousands of dollars since we switched to them 2 years ago. We used to have about 25 technician calls a year for our 15 units - now we may have 3-4 a year, and they are generally very simple and inexpensive (remember, I have 15 RTUs to keep up and running, not just one like most people, so only 4 service calls a year is incredible for 15 units, especially considering several are over 10 years old). They are fantastic at identifying potential issues while doing maintenance and getting those issues repaired before the units go down. Even better, they have

Donnie had visited my home for routine maintenance on the air conditioning and did what was necessary and more to make sure the ac is up to par. Since he's also a duct specialist, he went out of his way to provide an estimate on the cleaning and scheduled an appointment for the work later on. I wouldn't have known about his skill set until he volunteered the information. My mom and I definitely considered Donovan to do the duct cleaning and it was the luck of a draw that we met Donnie.

Our AC unit was past its prime and needed replaced. I placed a call and made an appointment for an estimate. Aaron Thacker came out. He was knowledgable, knew the existing equipment, knew the equipment he was selling, and provided me a quote on a new system. Aaron inspired confidence, didn't try to oversell me, and I arranged to have our new system installed.
Brian Fluharty came out on time the next week to install. He was polite, courteous, and skilled. He came out at 8am and was done by 1pm. He left our place clean; vacuumed and took all the trash away. The new unit is great! The old one
