HVAC reviews in Waltham, Massachusetts

We are so grateful for PerfectTemp HVAC Service! William returned our call just a few hours after we reached out, even though it was after regular business hours. He came over the next day to check out our AC and gave us a quote for a new unit. William walked us through different options and prices, and explained the great warranty they offer. He made sure our AC installation was scheduled right before our daughter's graduation party, so everything would be ready for our out-of-town guests. David and Brandon handled the installation and did a fantastic job. They were professional, careful, and paid attention to every detail. After they finished, they left both our basement and yard looking clean and tidy. Our new AC is running perfectly and keeping our house comfortable, which is especially important during the hot Massachusetts summers. The office team was super helpful, too, and helped us find financing that fit our budget. We are really happy with the whole experience and would recommend their AC repair and installation services to anyone.

We recently moved into a new home and needed a new furnace installed, so we reached out to PerfectTemp HVAC Service. Since we had a great experience before, we knew exactly who to call for our furnace repair and installation needs. David and Brandon handled the installation, and their professionalism and strong knowledge of HVAC systems really stood out. The customer service was excellent from start to finish. A few years ago, we also had a furnace and A/C installed by William and David. They provided a quote quickly and scheduled the installation right away. Everything was done efficiently and they were very friendly and helpful throughout the process. We’ve recommended this company to several friends because of their reliable furnace repair services and outstanding customer care. If you need furnace work done, they are definitely a top choice.

brandon is one of the most knowledgeable and honest furnace repair techs i've had in my home. after dealing with furnace issues in waltham for years and having other companies just do temporary fixes, i was really impressed. he quickly found all the problems with my old furnace and worked hard with my home warranty to get a full replacement of the indoor unit. even though my outdoor unit was still running and not covered for replacement, he offered me a great price to swap out the condenser, so now my whole heating system is brand new and working perfectly, just in time for the cold weather. the cost was very fair compared to others i’ve tried. plus, brandon is friendly and easy to talk to. highly recommend perfecttemp hvac service for furnace repairs.

Our experience with the heater repair team was excellent from start to finish. We had two furnaces replaced, and the results were fantastic. The technicians, especially Brandon, were professional and courteous throughout the entire process. Since my wife and I work from home, we really appreciated how careful they were to minimize any disruption while they worked on our heating system. We compared several companies for this important job, and this team offered the best value and the most flexible financing options we found. I highly recommend them to anyone looking for reliable heater repair or replacement—they should be your first call!

our old ac unit needed to be replaced, so we called an ac repair company in waltham. we spoke with grant, who explained the price, installation process, and warranty details in a very clear way. we were able to get the installation scheduled a day earlier than we expected, which was great. on installation day, technician william showed up and got straight to work. he was very efficient, professional, and made sure the new ac was installed perfectly. tanner came along to help, and he was friendly and worked hard to get everything done right, even making sure the area was cleaned up after the installation. grant also helped register the equipment for the warranty, which was a huge help for us since we’re always busy. overall, everyone did an amazing job and i highly recommend them for anyone needing ac repair or replacement in waltham.

This was my first time leaving an online review, but I felt I had to share how great the HVAC service was. After another company told us we had a gas leak, shut off our furnace, and gave us a very expensive quote to fix or replace it, we decided to get a second opinion. A friend suggested this company, and we’re so glad we called. William gave us a quote for a new furnace that was much more reasonable than what we had before, but before moving forward, he sent Grant out to double-check everything. Grant carefully inspected our heating system for gas leaks and other problems. He found that there actually wasn’t a gas leak and told us that we didn’t need to replace our furnace right now. It’s rare to find such honest and reliable HVAC professionals. We’re very grateful for their honesty and expertise, and we’ll definitely call them again for any future heating or cooling needs.

I’m so impressed with PerfectTemp HVAC Service! Our heater stopped working right when we needed it most. I found them online and gave them a call early in the morning, and they had a technician at my home within about an hour and a half. William was the person I spoke to on the phone, and he was extremely friendly and polite every time we talked. The technicians were fantastic, especially Grant. Grant took the time to explain everything to me, showed me exactly what was wrong with the heater, and let me know all my options. He was very patient and understanding. William also checked in by phone before starting any repairs to make sure I understood what would happen next. They got my heater up and running the same day, so I’m warm and comfortable now. Grant also gave me helpful tips on how to keep both my indoor and outdoor units working well, and included a great warranty on one of the parts they replaced. I’ll definitely be recommending them to anyone who needs heater repair!

I've had PerfectTemp HVAC Service come out every year to check and service my heater, and they always do an excellent job. Last winter, when my old heater finally stopped working, Tanner explained that it was too outdated to find replacement parts. I knew it was time for an upgrade anyway, so I went ahead and got a new heating system installed. The price was fair, and I really appreciated having several years to pay it off with no interest. The technicians are always professional and friendly, taking the time to explain everything in simple terms. If they ever find an issue during a heater inspection, they show me pictures so I understand what's happening. It’s hard to find honest service like this in Waltham, especially when you need your heat working during those cold Massachusetts winters. I feel confident recommending them—reliable and trustworthy every time.

After our heater suddenly stopped working during a cold spell in Waltham, we contacted PerfectTemp HVAC Service. David responded very quickly and got to work right away. At first, nothing seemed obviously wrong with our heating system, but David took the time to carefully check everything. He suggested we start by replacing the thermostat, which we tried, but it didn’t fix the problem. David returned promptly and performed some detailed electrical testing on the furnace’s motherboard. He was able to find the real issue there. He didn’t charge us extra for coming back a second time, and the next morning, he arrived again with a new motherboard ready to install. Once more, there was no extra fee for the service call. The cost for the repair matched what I had expected for this kind of heater repair work. I’d definitely recommend this company to anyone in need of reliable heater repair in Waltham. They really care about finding the true problem and helping customers, not just selling you parts you don’t need.

I can't say enough great things about the team that helped with our HVAC systems here in Waltham. After dealing with a lot of problems from another company, Brandon came out to service our heating and cooling units. He did a thorough diagnostic check on all the systems and explained everything to us in simple terms. We were given clear options to get our HVAC units running at their best. William also called to go over the available solutions and set up a convenient timeline for repairs. Compared to our previous experience, their professional and knowledgeable service really stood out. I highly recommend their skilled technicians and excellent customer service.

After putting off a recurring issue with our furnace for quite some time, it finally stopped working. Brandon came out to our home in Waltham to check things out. He was very thorough with his diagnosis and explained everything clearly, letting us know exactly what needed to be done. Since our furnace was older, we decided to go ahead and replace it, and we also added a new AC unit. Brandon was always quick to answer our calls and patiently responded to all our questions, offering helpful advice for people like us who aren’t experts in furnace repair. We’re really glad to have a trustworthy local company in Waltham to rely on for future heating and cooling needs.

we highly recommend this team for furnace repair in waltham! we had a big project, taking out all the old attic ductwork and ceiling vents. brandon and his crew handled everything so smoothly. they worked together with another company to make sure the new furnace system was installed perfectly. it was amazing to see how everyone knew exactly what to do, like a well-oiled machine. the team was organized, responsible, and cleaned up as they worked. the whole job was finished in just one day. if you need furnace work done, you should definitely call them!

We started working with PerfectTemp HVAC Service about 25 years ago. Since then, they have replaced our furnace and always taken care of all the maintenance and cleaning for our heating system. William was often part of the team helping us. Recently, our old boiler needed to be replaced, and while we were waiting for better weather to do the work, our oil tank started leaking. William came by, found two leaks, and patched them up until the tank could be swapped out. Two weeks ago, William and the team came and removed the old oil tank and installed a new one. It was not a simple job, since it seemed like the house was built around the tank. They even had to take out stairs to get the new tank in, and cut the old one in half to get it out. They put the stairs back within a few hours, and cleaned up so well you couldn't tell work had been done. This week, William came back and put in the new boiler. they always do a great job, are polite, professional, and treat our home with respect. their prices are fair too. i can't recommend them enough for furnace repair and heating service. great company

Our 30-year-old furnace stopped working right before the holidays, and we needed help fast. We first had another company check it, but their price seemed high and they couldn’t install the new heater for more than a week. We reached out to PerfectTemp HVAC Service, and Tanner showed up quickly the next morning. He explained three good options for a replacement furnace and answered all our heater repair questions. The new unit was installed the very next day! Grant also helped us understand the financing over the phone, making the whole process easy and stress-free. The price was fair, and we are really happy with our decision. Our house is warm again and we highly recommend their heater repair services.

We were recommended this AC repair service by a neighbor and are really glad we chose them. Booking an appointment online was simple, and Grant arrived right on time. We hadn’t had our air conditioning serviced in quite a while, and Grant took the time to explain everything about both of our AC units. He was upfront and gave us clear advice on what needed to be done. He found that the Freon levels were low and discovered a capacitor that needed to be replaced. Grant even went up into the attic to do a complete inspection, making sure everything was working as it should. After adding several pounds of Freon to both units and installing a new capacitor, our bill was actually less than we expected. Now, our 12-year-old AC units are running great again. We’re really happy with the whole experience and would definitely recommend this AC repair team to anyone in Waltham looking for quality service.

I had a great experience with this HVAC company from start to finish. When I was getting quotes, Grant was the only technician who actually took the time to go under my house and carefully check my current HVAC system and all the ductwork. I needed to upgrade from a single gas-pack unit to a split furnace and AC setup, which meant the installation was a bit more involved than just swapping out the old system. The installation team worked efficiently, took out the old equipment, and set up the new heating and cooling systems quickly and professionally. I’m really happy with the work they did and would definitely recommend them to anyone looking for HVAC services in Massachusetts.

Our furnace stopped working right before one of the coldest days of the season. We reached out to PerfectTemp HVAC Service, hoping for a quick fix. Grant got back to us quickly and arrived at our home the very next morning. He had our furnace repaired and running smoothly in no time. The technician was knowledgeable and friendly, and the person who answered the phone was very helpful. We’re very happy with the service and will definitely use them again for any furnace repair or heating needs.

I've been a customer here for over five years, and I've always had a great experience with their furnace repair services. Most recently, I needed my furnace replaced at my rental property in Waltham. Brandon and his team were extremely helpful and patient throughout the entire process, starting with the friendly person in the office. Brandon took the time to explain how everything worked, especially when it came to dealing with my home warranty company, and he helped me get my claim sorted out. Even though it was a big expense, I'm glad I chose a team of professionals I can trust. I wouldn't go anywhere else for furnace repair or heating system work!

PerfectTemp HVAC Service was chosen by our builder to handle the HVAC installation for our new townhome community in Waltham. After moving in, we also had them add a humidifier to our furnace. Because we were so happy with their work, we decided to sign up for a service contract. Every visit has been a great experience—the technicians are always professional, and scheduling is quick and simple. Special thanks to William, who has come out for maintenance a couple of times. He is always friendly, efficient, and takes the time to explain everything and answer our questions. We highly recommend their excellent HVAC services!

I had a new boiler system installed for radiant floor heating in my home. Grant and the team who came out were very knowledgeable, friendly, and professional throughout the whole process. The quality of the installation was excellent, and they made sure not to rush anything, taking the time needed to do everything the right way from start to finish. My new system is running perfectly, with no problems at all, which is impressive considering all the plumbing and detailed work involved. I am very happy with the results and would definitely recommend this company to anyone in need of HVAC services, especially for heating systems.

I had an excellent experience with PerfectTemp HVAC Service when our AC stopped working in Waltham. Thankfully, they were able to fit us in quickly due to a last-minute opening, and a technician arrived at our house the same morning I called. The person who answered the phone immediately recognized my account and made the process really easy. Brandon, the technician, did a fantastic job. He was friendly and respectful, always wearing shoe covers when coming inside. He explained each step of the repair so I knew exactly what was happening. Brandon quickly figured out what was wrong and had our air conditioning running smoothly again in less than an hour. While he was here, I learned about their maintenance program and decided to sign up for regular AC checkups to keep everything working well. We bought our AC and furnace from them several years ago, and we've been very happy with both the products and the service. I highly recommend their team for anyone needing AC repairs or maintenance in Waltham.
