Although parts for our hot water heater were still under warranty, David's Heating and Cooling…read morequoted 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.

David's is the BEST! I used Carters in July of 2024 to clean my oil furnace. I have previously used…read moreDavid'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.

I called 128 Plumbing about one cracked drain pipe. I was told my entire house needed to be…read morerepiped. The estimate (#435094323) was $30,275 to demo every wall and ceiling necessary, disconnect first- and second-floor bathrooms, toilets and sinks, and replace the main stack. That was presented to me as the only option -- no alternatives, no phasing, nothing. And it did not include the roughly $6,000 I'd need to close the walls back up and reinstall fixtures, or the ~$400 roofer I'd have to hire and coordinate myself. Their own estimate puts the hole repair on the customer in writing. All in: nearly $37,000. Meanwhile my first-floor tenant was told she couldn't use her bathroom or her kitchen. When I hesitated at the number, I was told that at least if I sold the house I'd "have retail value." That's the line that made me stop and get a second opinion. Thompson Plumbing came out, found the actual leak -- old hubbed cast iron serving the kitchen -- and repiped it. $2,995. My final invoice was $3,420, and that included an unrelated frost-free silcock I added on. My toilet was fine. My kitchen sink was fine. My tenant's kitchen and bathroom were fine. Not one wall was demoed. Same house. Same leak. Ten percent of the price. I'm not going to speculate about why the two assessments were so far apart. I'll just say this: if 128 Plumbing tells you your house needs a $30,000 repipe, get a second quote before you sign anything. I nearly didn't, and it would have cost me thirty-three thousand dollars I did not need to spend.
