What Our Happy Customers Are Saying

Brandon was very good to work with in diagnosing our water heater problem, and helping us get information on replacement options. Sadly, the current tank is cracked beyond repair, but it’s at least 20 years old, so not too surprising. We appreciated his coming out promptly, and his good communication.

Brian was great to work with for our furnace tune up! He is a great communicator, was able to answer some questions for us and also gave us good tips on how to keep things running smoothly! He really went above and beyond and we appreciate that so much.

We really appreciate the good job Brad did on our spring AC inspection/tune up. He was prompt and professional. As always we are happy with the service from Harker.

Roger was very good to work with. He was on time, thorough, and more than willing to answer any questions we had. It’s nice to know the AC is all set to go for summer.
Ty was very polite and considerate and did a thorough job.

The service was great, and on time. The service representative communicated what he was doing and how long it would take. Very professional and clean. I will be using Harker in the future.

They came out and diagnosed a problem with my furnace and were able to get a new one installed the same day. Was very impressed with Matt and Eric’s quality of work and greatly appreciated Brandon walking me through my options very clearly. Will definitely be using for other services and recommending them to friends.

Making an appointment was easy online. Communication about arrivals was good & useful for our schedules. Kyle was helpful, explained what he was doing, and communicated throughout the process. Harker is professional and we’ve always had a good experience. Recommended.
