HVAC reviews in Waltham, Massachusetts

I've been using LeBlanc since we moved into our Newton home. Shawn and the team of techs are quick to respond and professionally provide all services needed. I highly recommend

They came to my house to provide me with a quote and they never followed up. Called them several times and keeps promising the quote delivery but never delivered on it.

How can you trust a this plumber to do good job if they can't even deliver on a quote?

I called on a Monday morning and they asked if I was available between 10 and 2, THE SAME DAY! So I get a call and a young man named Jake said he would be here in 10 minutes, if that was OK! He was so polite, respectful and did a great job cleaning out our HVAC unit! I cannot say enough about Jake and the office staff! Greatly appreciate good people and good businesses!! Thanks again guys!

Called on a Friday with a no AC issue for upstairs zone. Service tech was at my house in under 4 hours, diagnosed and fixed the issue and had AC up and running again.
Office told me they would do their best to fit it in and delivered as promised. Service tech was courteous and knowledgeable. Highly recommend

These guys were the first to come when I made the call. My central air stopped working over night. I made several calls and these guys actual showed up.Very professional on the phone and at my house. They had my AC back on very quickly. Thank you LeBlanc Mechanical, highly recommend!

We’ve been working with Leblanc Mechanical, Matt, Nick, Randy and their team for close to 20 years. I just replaced a furnace and their team was efficient, super neat and professional!

Excellent service!! We were without heat and the LeBlanc team worked hard on making sure my family was warm by nightfall. They explained everything to me clearly and charged me fairly. I couldn’t be happier and you will be too.

I've been working with Randy LeBlanc and his whole team at LeBlanc Mechanical for over 20 years. They've worked on my personal properties and my rental properties. They've done everything from a simple water heater replacement to removal of an old oil furnace to gas heat with central A/C. The reason I've used them for so long, is that they are extremely professional, reliable and punctual. I highly recommend anyone to use LeBlanc Mechanical.

We have been customers of LeBlanc Mechanical for 30 years. LeBlanc has installed two complete HAVC systems and flawlessly serviced them. They have always been there when we needed them.
One of the best service companies we have used over the past 30 years.

I was very please with the professionalism being given by the technicians when they arrived. They were efficient, polite, and got the job done quickly but took care in the repair. I thought LeBlanc did an outstanding job and I would highly recommend them to others if I were to be asked. I look forward to future maintenance and we are very grateful for the work performed.

Called after a long memorial day weekend when my AC went out, shortly followed by my entire HVAC system dying. LeBlanc had a technician to my house in a few hours, and the problem was traced and repaired the next day. Absolutely pleased with the speed, professionalism, and quality of the services provided. Would not hesitate to recommend.

I was away for a few days and switched on the heat via my nest app a few hours before as I usually do. However, when I came home my heating had not started working and it was 44 F in my living room. I called Randy from LeBlanc Mechanical and one of his service guys came out right the same day. He detected the failure of the motor within minutes, went to get the new one and built it right in. He also explained how my heating unit works and what to pay attention to. Their responsiveness and professionalism is outstanding, I highly recommend LeBlanc Mechanical.

Our hot water heater needed to be replaced. While chatting with a friend she recommended LeBlanc Mechanical. I hadn't had good experiences with similar companies in the past. Our experience with LeBlanc's phone representative and, several hour later, one of their technicians was excellent. The new hot water heater was installed quickly and at an affordable cost. What a relief. Definitely give LeBlanc Mechanical a try.

My family has used LeBlanc over the years and have found them to always be reliable and very good. Recently they proved themselves to be even better. During this terrible heatwave, my elderly parent's AC stopped working. I immediately called LeBlanc and explained the situation. I'm well aware that during heatwaves they are especially busy. I expressed my concern for my parents and their well-being. During the day I was contacted several times and told they would do their best to get there. And they certainly did!!! Randy went to their home the same day and was able to quickly fix the problem. We highly recommend LeBlanc for their service, dependability and compassion!
Thanks Randy and LeBlanc Team!

These people are impossible to work with and I would not recommend them to anybody.

I reached out to LeBlanc because my A/C isn't working. First they tried to push out my scheduled appointment by a week, claiming that they were dealing with a lot of "no A/C" calls and needed to reschedule routine maintenance calls. When I scheduled the appointment, I clearly told them that my A/C wasn't working - this wasn't a routine maintenance call!

When they did come out, they determined that the condenser was broken and that I needed to update my system because it uses an old type of refrigerant. They were supposed to get back to me within a couple of days with a quote. It's been nearly a month now, during which I've called them several times to check on the status of the quote. Each time, they assure me that they'll get back to me within 1-2 days. Each time, they don't get back to me at all! To this day, I still haven't received a quote.

If LeBlanc doesn't have the capacity to service my home, they should just tell me that. Giving me the run-around for nearly a month is incredibly unprofessional - especially when we're dealing with unprecedented temperatures and I'm trying to keep the house cool for my children. Whatever is going on over at LeBlanc, they clearly can't be relied upon and should be avoided in favor of other, more responsive companies.

They’re contracted with my apartment to work on our AC unit but LeBlanc sent a third party contractor and they didn’t fix the issue. Leblanc was supposed to order the control board part but never showed up to install it and my apartment manager says Leblanc is not returning calls to come fix the issue. This has been going over for over one month now.

Corey 10 Development is the apartment company that Leblanc is supposed to be helping (which I live in a Corey 10 apartment). Middle of summer and no AC is not acceptable and it’s apparently all because Leblanc is not communicative.

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.

The smart hvac guy I ever met

Our home feels refreshed after these experts meticulously repaired our ducts. They arrived promptly and finished the job in just under an hour. Highly recommend!

The HVAC technician handled a heating issue during cold weather. The HVAC technician carefully checked the system and restored proper heating without delays.

After the repair my thermostat works flawlessly and the technician was both prompt and knowledgeable They took the time to explain everything clearly Highly recommend
