Had Carly out today! She did a very thorough cleaning and check for furnace and fireplace. Very good at explaining and communicating what she was doing, Great job! Thanks all!

Extremely happy with the service we just received. The guys were very friendly, worked fast and we’re super clean. Will most definitely recommend Harold’s Heating.

Thank you to Harold’s Heating for prompt and efficient service. We really appreciated JP’s attention to detail. His customer service and diagnostic skills are exemplary!

My furnace took a dump and I was told by others it would have to be replaced with a new one because replacement parts were obsolete. I was told that a new one would cost about $3,000.00. I was advised to call Harold's Heating for a quote. Mike Harold came the next day, took a quick look, went to his truck, came back in and 10 minutes later I was ready for winter for a cost of less than one-tenth the price of a new one. He could have taken me to the cleaners but ended up saving me about $2,800.00. If you are having furnace problems make sure to call these people first. You won't be sorry.

Excellent Service. I had the full furnace and AC installed last year and last week and i called for some work and it was immediately resolved by sending two guys on the same day with no charge. Great after sales service. Highly recommended.

I've been inspecting homes for over 23 years, I don't know "Harold's Heating" but I sure know their work! I inspected a home recently where a furnace - A/C upgrade had been completed, and a complete conversion from electric baseboard to forced air gas, fabulous job, well done!
