Tina was very nice and understanding. I talk to her about the invoice I receive that have incorrect charge. She promptly said that she will credit those incorrect charge. The service response time is fast.

After arriving home from work on Friday to find a cold house and my furnace flashing a code I could not remedy. I called Harker (after hours) and Mark was at my house within an hour. He was able to quickly identify the issue. Although having to order a part for a long term fix, Mark was able to get us heat for part of the weekend (luckily it was not during a polar vortex that weekend). Mark returned Monday with the part, and the furnace has been working great ever since! I can’t say enough how nice it was to work with all the professional people at Harker…They have earned a loyal customer in me. jb

Jeff was early for the appointment - always a plus. He was professional, knowledgable and took the time to answer all of my questions. His inspection was thorough and he went the extra mile in my opinion by being willing to clean the humidifier attached to the furnace. Was an all around positive experience.

Our Boiler went out at the start of season with a cracked heat exchanger, leaking water. Shopped around, did plenty of research and narrowed our options. Harker was not the cheapest although their guys (specifically Aaron) was top notch. From all my research, the theory floating around was the same; the quality of hardware today are very similar, the installation is what matters most. Pay the extra for top quality techs and reap the long-term savings/benefits. Properly installed hardware will last. We chose Harker even though they were not the cheapest out there. We are firm believers in that you usually do get what you pay for. So far we are very happy. If something goes wrong or is not addressed within a reasonable time in regards to the new boiler, we will update this review to share. We are also moving forward with replacement of our A/C unit with Harker over the next few weeks. I am attaching before and after photos.

Jeff did a furnace check and tune-up today. He came at the expected time. He was very personable and answered our questions. He went over items that he checked and everything looked good. He asked whether we had changed the batteries in our thermostat and then showed us how by changing them.

We were very pleased with this service visit. We will continue to use Harker Heating for our furnace service needs and hope to get Jeff again on our next service call.

The furnace winter inspection and adjustment performed today by Wayne L was outstanding. He was extremely conscientious and did excellent work. We had a fun conservation while he worked: I asked him numerous technical questions about the furnace's operation, which he explained very clearly. It was a very positive experience having him at our house and working on our furnace.
