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. It was well worth it to have peace of mind entering the heating season.
