Best Heating & Air Conditioning / HVAC In Waltham

“So a true story here. Our AC failed this weekend Fourth of July. Big heat wave wave in Boston as we all know. I called several HVAC companies and of course they’re all very booked but a guy shows up from a company I shall not name and after doing a little bit of examinations tells me I need a new AC system immediately. It’ll be eight to $12,000. He can do it Monday. Meanwhile, I had also called Ken and he showed up (I believe this is Ken himself), about an hour and a half later. He proceeded to take a look and then simply replaced our capacitor unit and hosed off the condenser coils with my water hose. Immediately, the fan on the external unit at our house was functioning again which the other guy told me was broken and needed to be replaced, hence need for full system replacement. So I had a functional AC system…for $375 vs $10,000!!! What can I say Ken? It’s an honest guy and straight shooter…outstanding service. Highly recommend and not scam artist. Thank you Ken.“

“Great service from Genove Oil. I had been looking for a long time for an honest reasonable HVAC company. I was pleasantly surprised. Very knowledgable and they found an issue no one had ever found. Have already referred them to others and look forward to using them again!“

“Professional and honest air duct cleaning service in Natick. Nick arrived on time, explained the process clearly, and showed photos of the ducts before and after. The airflow in the house improved right away and there’s noticeably less dust. Fair pricing and no pressure. Highly recommended.“

“Murphy Fuel did a great job installing our mini split system last fall. Terry and the team were professional, responsive, and kept everything on schedule from start to finish.

Our setup was large and had a complicated layout, but they handled it without any issues. During the estimate and planning phase, Terry was especially accommodating—he took the time to walk through options with us and was flexible when we decided to change the originally planned locations. That level of patience and willingness to adapt really stood out.

After the installation, they even came back to make sure everything was working properly, which we really appreciated. Overall, a smooth experience and a team that clearly cares about doing things right. Would definitely recommend.“

“Outstanding Service from Andrew at A.E. Carter Plumbing

I cannot recommend Andrew at A.E. Carter Plumbing highly enough. He has previously completed work at my primary residence, numerous times, and the quality of his work, professionalism, and reliability left a lasting impression.

Today, he came through for me again in a pinch at one of my rental units, and once again exceeded expectations. Not only did he show up and fix what he initially went out for, but he also returned when I called him in a panic when my delivery/install company refused to install my tenant's new washing machine.

Andrew was responsive, knowledgeable, and efficient, quickly resolving the issue while keeping me informed throughout the process. As a property owner, having a trusted professional who shows up when needed and gets the job done right the first time is invaluable.

His workmanship is excellent, his customer service is top-notch, and he genuinely cares about helping his clients. If you're looking for a plumber who is dependable, skilled, and responsive, Andrew is the person to call.

Thank you, Andrew, for once again providing exceptional service when it mattered most!“

“Hayes oil is a great oil company, I would always recommend them 100% Lisa does a great job!“

“Mr. Hickey just helped make my new bathroom a realty. He showed up when he said he would, did the work he said he would do, charged what he said he would charge and stayed incredibly patient with my questions and, most importantly with Otis (my overly friendly, wants to help with everything, dog.) He took what was deemed a plumbing mess and made it a thing of beauty and perfect functionality. I know I will not need him anytime in the near future, but you should consider him for all your plumbing needs. You will as happy as I am if you do!“

“Very honest and responsive....100% recommend them! Best plumber I've ever used. Showed up immediately for a leaking pipe, quickly resolved the issue, and charged a fair price.“

“Dependable,thorough cleaning. Staff helpfull and pleasant. Silmar is a pleasure to deal with.“

“Taylor and Murphy were extremely responsive when our A/C went out the day before the worst heat wave in Boston history. They trouble shooted the issue and we opted to replace the entire system since our units were 21 years old. They ordered the necessary equipment and came on the scheduled day, the technicians were very capable and worked efficiently. They were very tide and left virtually no clean up for us. Wayne Taylor was especially easy to work with and gave us very reasonable pricing. We would highly recommend.“

“Scott came highly recommended by someone I trust, a previous customer who was exceedingly pleased with his installation and service. I found his responsiveness to be timely, his demeanor professional and above all, his rates and service are simply the best! He's also in high demand... a good sign!“

“Thank god for this company. My main air-conditioning system and floral cooler stopped working. I wasn’t sure who to call for both AC and a floral cooler. I went on google and found this company. The first company I tried, told me my coolers were old and I should just get a new ones. Called Leblanc and they came over and fixed both on same day. This literally saved my flowers & team for a huge event I had. Cant thank them enough. Try them and thank me later.“

“Woke up this morning freezing, called Burns Mechanical and they came in just over an hour! The good news it was just the furnace doing its job. Snow has gotten into the intake and froze. To prevent carbon backup it shuts down. Thank you for heat and great work!“
