What Homeowners Say About Mersey Heating’s HVAC Services

“Just had a new Lennox Elite two stage furnace and air conditioner installed today. This was a deal through Costco. Good discounts and a competitive price, not the lowest, but the service and the overall install and product were excellent. I would highly recommend Mersey Heating if you’re looking for a top notch install with a great line of products and service.”​

“Mersey has excellent products and wonderful service. We had them install our furnace and air conditioning last year and have marveled at their service as well. Nick was our technician today and as with our other service people, gave us prompt, clear (explained everything he was doing), considerate service. 5 stars all the way!”​

“Mersey called to have my air conditioner inspected after one year of installation. This was to ensure that the unit was performing as it was to be. I requested Nick to come out as I had used him previously. He was truly polite and courteous and addressed all of my concerns with great patience. He performed a thorough and complete check of the unit paying attention to all detail as I requested. He also followed proper covid-19 protocols respecting my home. Nick really is top drawer and I will be requesting him once again in the future.”​
