On the coldest weekend of the winter a homeowner lost heat, called at 7:10 on a Sunday morning, and John Conway answered. In that February 2026 account he was at the house within three hours, and when the part could not come until Monday he lent the family enough space heaters to bring the house from 49 degrees back up to 74. Conway Heating and Air works out of Billerica, and its customers describe reaching John Conway himself. One May 2026 reviewer whose house was built in 2017 says Conway installed the system then and that the number still goes straight to the owner. Its BBB page is an accredited A+ and lists residential and commercial air conditioning, heating contracting and system repair, duct cleaning, ventilation, parts and filters. What people call about is heat or cooling that has failed at the worst moment, and the answer is almost always same-day. A July 2026 customer during the Fourth of July heatwave says she almost cried when he said he could come, and that he came and fixed the unit. Another in May 2026 was at 97 degrees with a dead air conditioner and had it running that day; a third says he was at the house within twenty minutes. One customer in July 2026 says he responded immediately, had the part in his truck and was finished in minutes. In a July 2025 review a homeowner with breakdowns on both systems inside eight days says he came twice within hours of the call, with the right parts on hand each time. The buying side gets described as plainly as the repairs. A September 2026 customer with a failing system says John laid out options at several price points and never pushed the most expensive one; a February 2026 customer who chose to replace a furnace says he was open about the alternatives and did not upsell. In a June 2025 review a homeowner who thought another contractor's condenser quote looked high says John answered the phone himself and came out that same day for a second opinion. The work runs to installs and upkeep too: a new system in an October 2025 account, annual maintenance in a November 2025 one, and heating maintenance with duct cleaning in March 2026. A strong call for an emergency air conditioning or heating failure around Billerica, and for a furnace or system replacement you want quoted straight. Ask how weekend and after-hours calls are billed, and whether annual maintenance covers both the heating and the cooling side.
I would highly recommend Conway Heating and Air Conditioning. Super fast service and fair prices. When I had a failing AC system, John and his team gave us multiple options at different price points to find the best solution for us. They never pressured us into choosing the most expensive option and even encouraged us to get other quotes to make sure we were getting a fair price. After getting other quotes, we found that Conway was more than fair. Great service, honest people, and a company that truly puts the customer first. I will definitely use them from now on.
John is my go to guy for any issues with my HVAC system for the last 5 years. He is very knowledgeable and gets right to the problem. Recently I had issue with the AC not working. It took less than an hour for him to fix the problem. His prices are fair and reasonable. I trust him to not recommend unnecessary fixes. I highly recommend him for any HVAC issues.
Excellent prompt service and reasonable rate
Honest, super knowledgeable, Great service
We were having an issue with our AC over the weekend. Someone recommended John to me on Monday at work. He came out the next morning and took care of our issue and charged us an extremely reasonable price. Highly recommend him and we will use him again for any future issues.
