HVAC reviews in Concord, California

Brody and James once again delivered outstanding AC repair service. They showed up right on schedule and were very respectful while working in my home. This visit, they took care of my air conditioning maintenance quickly and also handled the installation of my new Nest thermostat. Brody was extremely patient, explaining how to use Google Home and helping me set up the Nest device step by step. The bill was sent to my email before they even finished up. I’ve always been impressed with Brody’s friendly attitude and trustworthy service—even when I couldn’t be home. Both Brody and James are genuine, reliable, and easy to work with. I definitely recommend their AC repair and maintenance services to anyone looking for honest and professional help, especially when it gets hot here in California!

The team did a fantastic job with our heater repair and installation in Concord. Brody, who led the crew, really knew his way around the system and made sure everything was done right. The workers were efficient and paid attention to all the details while installing the vents, ducts, and the entire heating system. Dwayne kept the team well supplied and had a great attitude, which made the experience even better. The crew also made sure to keep the workspace clean throughout the job. James in the office was very helpful and kept me updated on every step, showing real professionalism. Overall, I’m very happy with the service and would recommend them for any heater repair needs.

i don't usually write reviews, but the service i got from the hvac team was outstanding. i recently moved into a new home and was still getting used to the heating and cooling system. one day, my heater wasn't keeping the house warm, so i called for help. brody came over quickly, checked the furnace, and it was a relief when he explained everything was working fine. he took the time to show me how to reset the thermostat and made sure i understood how the system works. brody even followed up a couple of days later to make sure everything was running smoothly, and he didn't charge me for the extra check. really great experience with this hvac service.

After my heater stopped working one morning in Concord, I called for repair help. They were able to send a technician out quickly—just two days later in the morning. The technician, James, was very professional and thorough. I expected the repair to be costly, but it turned out to be just a small part replacement, which saved me a lot of money. James had the heater running again in about an hour. This is actually my second time using their heater repair service, and both times have been excellent. The team has always been on time, friendly, and affordable. I’m very happy with their service and highly recommend them if you need heater repairs in Concord.

After noticing an unusual smell coming from one of our heating vents, I reached out to Climate Source HVAC/R LLC, my go-to for heater repairs. Brody showed up the next day and explained that, in his experience, odors like this often come from rodents near or inside the heating ducts. He was very thorough—he offered to check under the house and quickly found and removed a dead rat that was the source of the smell. The problem was fixed quickly and for less than I expected. I've always received honest and reliable service here. Highly recommended for anyone needing heater repair or maintenance.

Over the weekend, I heard a strange dripping noise coming from my heater system. When I checked, I found water collecting beneath the heater and even noticed a long trail of water on the garage floor. Thankfully, there was no water damage in the other rooms. Since it wasn’t an urgent issue, I called the office at Climate Source HVAC/R LLC on Monday morning to schedule a technician to look at my heater. James arrived on time for the appointment in the afternoon and quickly figured out that the drainage line in my heater system was clogged. He worked efficiently to unclog it and used a wet vacuum to remove all the standing water. Just like in past visits, James took the time to explain how I could maintain my heater and avoid similar problems in the future. The price for the repair was definitely fair, and I felt a big sense of relief once everything was fixed. I’ve had other technicians work on my heater before, but James really stood out for his professionalism and knowledge. If you get him for your repair, you can trust you’re in good hands.

I had a fantastic experience with Climate Source HVAC/R LLC when my air conditioning suddenly stopped working in the middle of a hot day here in Concord. I called first thing in the morning, and Brody arrived just a couple of hours later to check things out. He did everything he could to get my old AC unit running again since I was hoping to get a few more years out of it, but unfortunately, it was time for a replacement. Brody made sure I stayed comfortable by bringing over portable cooling units and then quickly arranged for a team to install a new air conditioner for me. The crew worked fast, were very professional, and made sure to keep everything tidy. They even adjusted some of the ductwork to give me a little more space in my already tight utility area. The cost for the new system was actually less than I expected, which was a great bonus. Highly recommend for anyone needing AC repair or installation!

i had a really good experience with climate source hvac/r llc. when my old air conditioning unit started leaking outside, i gave them a call and they scheduled a visit for the very next day. james came out and did a fantastic job. he was very professional, explained everything clearly, and even showed me some helpful tips, like how to change the filter in my attic. everyone i spoke with was friendly, knowledgeable, and made sure my ac system was running smoothly. the service was excellent and i’m very happy with how they handled everything.

My experience with this company has been really good so far. I had them come out to repair my heater and install a new thermostat in my home. From the very beginning, their communication was great—every call and email was answered quickly, and they explained everything in a way that was easy to understand. They even handled all the necessary permits for the heater work, which made things a lot easier for me. When I couldn’t find some paperwork for my property, they went the extra mile and contacted the right office to get it sorted out. During the installation, they first brought the wrong color cover for the heater pipes, but they fixed it right away and came back with the color I wanted. The technicians, James and Brody, were polite, respectful, and very professional throughout the job. They worked hard from start to finish and made sure everything was neat. There was a little confusion about how the heater would be installed, but when I asked them to try a different way that would look better inside my house, they listened and made it happen. i haven’t run the heater yet since the weather is still warm, but i feel confident the repair and installation were done right. If there’s ever a problem, i know the team will take care of it quickly, just like they did with everything else.

I’ve had Climate Source HVAC/R LLC work on my furnace and A/C a few times at my home in Concord, as well as at my son’s place. Every time, their team—James and Brody—offered fair prices and really impressive service. They always arrive on time, which I appreciate since it’s rare with other contractors. They replaced my old furnace and A/C, and even moved another unit and re-installed it properly, which helped me avoid having to buy a new one. They also put in a ductless split system in my garage, and now it stays cool and comfortable during the hot Concord summers. I truly appreciate their honesty, reliability, and strong work ethic. Highly recommend for anyone needing furnace repair or installation. Absolutely a 5-star experience!

I had been searching for reliable heater repair for a while. James came by after work to check if my heater could be fixed or if I needed a replacement. He found that my coil was bad, so I needed a new unit. The installation team was quick, professional, and got everything set up smoothly. My house warmed up really fast after they turned on the new system. The price was very reasonable and it even came with a 10-year warranty. The whole process was handled quickly, even during some tough weather. I’m really happy with the service I received.

I recently needed help installing a new Nest thermostat for my AC system in Concord. I was given a list of approved contractors to call, but the first company I contacted wanted to charge a high fee just to come out and didn’t seem very interested in helping. Then I reached out to James, and he was fantastic! Not only did he come out to install the Nest thermostat, but he also serviced our AC unit, replaced the old filter, and explained what kind of filter we should use to keep our system running smoothly. He noticed we had been using the wrong filter, which was making our AC work too hard, and gave us great advice on where to get the right one. James did all this for a very reasonable price, and he made us feel like valued customers. Now our AC is working great, and the new thermostat is easy to use. We’re so happy with the service and will definitely call again for any AC repairs or maintenance. Highly recommend!

Earlier this year, Climate Source HVAC/R LLC replaced my entire furnace system. They installed two new 4-ton, high-efficiency units, and also built a new plenum for one of the attic furnaces. The crew enlarged several ducts for better airflow and adjusted the dampers to balance the whole system. They installed a new smart thermostat for easier temperature control. James and his team handled the installation very well, paying great attention to detail. Dwayne helped me through the process and made everything simple and stress-free. Since I had the furnace work done in the cooler season, they couldn’t fully charge the refrigerant at that time. Later, when the weather warmed up, Brody returned to adjust the coolant levels and quickly figured out why my thermostat was sending high humidity alerts. He fixed the issue right away by adding more refrigerant. Everyone I interacted with was professional, knowledgeable, and respectful. After owning a home for many years, I feel confident calling this company for any furnace repairs or maintenance. I highly recommend their services.
