      Dennis is a great repairman. Took a look at my gravity heater and found the problem and had it fixed quickly.

      Thank You so much!

      I would like to take this opportunity to say thank you to Dennis and Moses for the amazing job they did repairing our heater. They were on time, never delayed or late, and very professional. Both of these men were extremely competent and confident in their craft. I appreciate how fast they identified the issue and how quickly they resolved the issue. The price was very fair for the services provided. I felt as if I was dealing with long time friends and family. Without pause or delay I would highly recommend this business to anyone in need of heating and cooling service. Great company!

      Dennis is legit. What I thought might be new gas furnace installation, turned into a simple problem fixed in 20 minutes. Honest, experienced, knowledgeable and on time.

      We had 2 old wall heaters in our in-law apartment that we asked Dennis to diagnose. He was able to fix one issue on the spot and gave a quote to fix the second one. He was transparent, letting me know the best strategy to ensure safety and efficiency. He didn't push for upgrades although when prompted, he agreed that our furnace wasn't the best quality. I'll be calling Dennis to optimize our heating soon!

      Dennis is quick, professional and kind. I used his service twice now-back to back years for a 20+ year old furnace. This small business is run properly with customer service focus backed by family values and decades of experience.

      If you want prompt service, efficient and effective work while dealing with reliable and timely responses, this is the place to consider.

      I had an issue with my wall heater, and I could not have found a man with more integrity to do the job. He was accommodating with my schedule, arrived promptly, quickly diagnosed the problem, and safety checked everything. He even made adjustments to save me costs with gas usage, and is an overall professional and kind individual. He will not overcharge you and you'll be glad you gave him a call!

      Dennis was great at fixing our broken furnace at the end of the holiday weekend. He came out super quickly, was friendly and professional, quickly identified the source of the problem and fixed it, and went above and beyond (even changed the batteries on our beeping carbon monoxide alarm we hadn't been able to find!). We are so happy to have a warm house again!

      Called Dennis because my wall heater was not working. I couldn't figure out what was wrong and was frustrated. Dennis was able to figure out the problem over the phone and walked me through the steps to fix it. He was very knowledgeable and nice. My heater is working again. Thank You Dennis! Highly Recommend!

      First to Review

      Dennis is a true master of his craft and some proprietor of his business. I was lucky to catch him when my furnace started acting up; he managed to make it over the same day.

      He's a skilled listener, both to his customers and the various sounds an HVAC system might make. He fixed my issue, and made sensible advice on what to invest in (and not invest in). He also takes pride in details, and found some additional loose ducting downstream of the furnace and taped it up to improve air loss. Left furnace in better shape than before it broke.

      Highly recommended.

      Dennis Heating and Cooling did an excellent job at getting my heater back in service. Dennis and Moses, were extremely professional, delivered the product and services that were in the service agreement, and gave me some educational-preventative maintenance tips to prolong my heater. Also, they arrived at the job site early, and left it better than they found it. I definitely will be using Dennis Heating & Cooling again.
