I contacted David's heating and cooling. Explained my situation (no A/C and it's the start of a heat wave) I was told they would be here in 20 minutes. And they showed up on time! Andy and Chris were very nice and professional. They spent about 1.5 hours and now my house is getting cool! (and less expensive than expected ) We will probably need a new one in the near future and will definitely call them to do it! We highly recommend David's heating and cooling! read more

Although parts for our hot water heater were still under warranty, David's Heating and Cooling quoted us over $900 in labor to get it fixed--a sum that exceeded the cost of replacing the unit altogether. The problem turned out to be a simple pilot light issue, yet their approach made it clear that running up labor charges took priority over taking care of the customer. Communication was poor throughout the process, and when we attempted to call for resolution, the woman who answered the phone hung up on us. As the President of a company that employs a large blue-collar workforce, I understand labor costs--but I also understand honesty, fairness, and professionalism. This company failed on all three fronts. We ultimately called Locher Plumbing, who were professional, communicative, and ethical. They quickly ordered the necessary part, returned for installation, and charged a fraction of what David's Heating and Cooling demanded. Locher proved that doing right by the customer is possible, and they earned our trust and future business. I cannot recommend strongly enough that others avoid David's Heating and Cooling. read more

David's is the BEST! I used Carters in July of 2024 to clean my oil furnace. I have previously used David's Heating & Cooling located in Merrimac, MA. but Carters pricing is much less expensive. Two nights ago I had the fire department at my home for Carbon Monoxide. Not only did the Carters Technician put the incorrect valve on my furnace but he never vacuumed it out. The incorrect valve and the poor quality of work almost killed my family. We were saved by our carbon monoxide detectors and the fire department. Please take this review seriously. Call David's at 978-346-4216 and spend the $300+ to have your furnace cleaned properly. Your lives are worth it! Pierre hands down is the best technician at David's. He's honest, trustworthy and competent. He fixed all our problems for $500. It was well worth it to have peace of mind entering the heating season. read more

Called to have my ac fixed. The service tech was incredibly nice. Came out and fixed it and got me running. I had told him what one problem was and he gave me a quote for a complete fix. I got a second opinion who told me that the system was not put in correctly. I called to speak to the owner to see how we could resolve this-his immediate response was that I was wrong, as was my second opinion. Incredibly rude, not willing to listen to customers. He was degrading and ignorant in my opinion. Not a company I want to do business with! read more

David's just installed new heatpumps and central A/C I'm my house and they did a Super job !!! They were very professional,careful,pleasant to deal with. They also were very understanding on questions and explaining the process ... Thank you Sincerely Scott! read more

The good: They respond in a timely fashion after leaving message for call back. The bad: Had limited hot water. Nice tech came out...did a few things to water heater. 925.00 Next day: still limited hot water. Called and they replaced thermostat on hot water heater. I spoke to owner to question bill and felt that the 40 dollar part installed which cost me 335 was upsetting. He told me if I dont pay, I will be charged with theft!! I have been a customer for 30+ years. He told me if I dont want to pay for the thermostst, the tech will come back and remove it which would continue to leave me without hot water. The whole thing cost almost 1300.00. Just out if curiousity, wonder the cost of new hot water heater is. Looks like I will have to replace it after all. Have a new company now. The 305 charge for burner cleanout now costs 200 with my new company!!! read more

After a recent private family medical emergency with our family , David's Heating and Cooling went ABOVE AND BEYOND for his employee and our family in helping us to resolve the issue. THANK YOU FROM THE BOTTOM OF OUR HEARTS, YOUR KINDNESS IS GREATLY APPRECIATED. I also had his employee Sean come to my home and address several issues I had with my heating system and he was on time, professional, clean and resolved all issues appropriately . I would highly recommend them at any time for all of your heating and cooling needs. read more

I have used David's Heating since I owned my home in 2011. Never had a issue with them until David sold the business. I was without heat a week ago and called David's Heating the game and stated it was a issue with the Gabe in my tank and to contact my propane company in which I did and the issue was resolved. Exactly a week later on another cold Sunday I lost heat again. They continuously stated the it was my propane company's problem and my system was fine. In fact David's Heating did not plug in a wire correctly so for a whole week my house could have had a fire. I was hung up on, system still not serviced and my propane company could not believe they left it the way it was mind you I already had an appointment to have it serviced. Nonetheless, they refund me in cash and hung up on me stating they didn't care if my house had burned down. I am appalled and the better business bureau has been contacted. This company went down hill after David sold it they should rename the company not to ruin his name. read more

I previously wrote a 1 star review for David Heating based on the poor service I received during the period when they were drafting a proposal. They did eventually send me a proposal and it was significantly more detailed and lower in cost than the others I had received up to that point. It just took two weeks, several bad reviews, and multiple, increasingly frustrated, phone calls. I accepted the proposal and then things moved much faster and more smoothly. The office was more responsive than with the proposal. The work was done quickly and professionally. I still have to ding them for the service I originally received, but I'm not unhappy that I went with David. read more

I've been a customer of David Heating & Cooling for years. Recently I told my son to contact them for service on his heating system. The service provided was absolutely terrible. When I called to talk to someone I was met my the receptionist that was rude and extremely unhelpful. Rather than offering to fix the issue she did nothing but become rude and insulting! When my son called, the tech that showed up told him that since he wasn't a customer they didn't really need to show up! None the less they took the $225 dollars from him and promised that if he got the heating system from them the money would be credited to the sale. Two weeks later, and multiple calls he still doesn't have the quote! When I called I was told it was still on the "wall" waiting for the owner to approve it! As I said rather than being helpful the woman that answered the phone was rude and uncooperative. Would I use David Heating and Cooling any more? I'm looking for a new heating company now myself. And I have about $10,000 in work I was looking to do this coming year (cooling) but given this string of events I wouldn't think of using them. Perhaps Steve will call me and explain this rude behavior! Otherwise I would advice you to go somewhere else. read more

When our furnace quit working overnight, on a weekend, we were in a mild panic, unsure if we would be able to get help and concerned about what the resulting expense would be for an emergency weekend call. Our entire experience with David Heating & Cooling was outstanding. From our first call, to the service technician that arrived to our home and took care of everything in the most professional, courteous manner, to the more than reasonable charges, considering the circumstances-I highly recommend! read more

Writing this for my mother, as she doesn't do computers. Her AC was running badly. She call one HVAC place, who never called her back. She was told by a friend to call David Heating and Cooling. The guy came next day, spent about 90 minutes going over her whole system. Fixed , and tuned it up. She was amazed at how quickly it got her place cool again. She was very happy with the service. read more

I have never experienced such a rude interaction as we had with both the tech and the owner, Steve..outrageous anger, inappropriate tone and language. Definitely lost our business.. Switching over to Knight Oil. Also, tech entered our home without ringing the doorbell or knocking and then got beyond angry and rude when the dog rushed him..this company doesn't have the customer skills to talk a situation through calmly. Zero to sixty on an anger level at which they are at fault. read more

I must give credit when credit is due!!! I contacted David's Heating on 1/2/19 @ 7:30 am for No Heat Oil Burner. Within a couple of hours I saw a blue van pull in my driveway (David Heating & Cooling). The technician (Andy) was a well trained well spoken professional tradesman. Within minutes Andy had troubleshot the problem. He explained in laymen's terms what was wrong with my boiler and replaced the worn piece part. Andy looked over the entire furnace prior to test firing it. He ran it through multiple (3) cycles and tests assuring the boiler was safe and fixed correctly. This was the kind service you got back in the good old days!!! Honest, Trustworthy, Extremely Reasonably Priced!! Highly Recommend!! read more

Do not call David Heating & Cooling if you are a new prospective customer. I called to inquire about problems with my heat pump system (in early January 2018); the representative informed me that her "boss" is not accepting new customers. She told me to call back in April and she will consider asking him if he wants to serve me. I will not be calling back. This was one of the rudest responses I have ever experienced from a service business. read more

We used David Heating and Cooling to install a new entire Heating and AC unit for our home. We were so pleased with the work they did! The service technicians arrived on time, they were professional and did a great job! The owner, Steve, gave us several units to choose from and helped us choose the right unit for our home. It is refreshing to find a service company that you can trust and rely on! read more
