I called next morning and next business day he returned and completed repair. Again on time,very professional and leave no dirt or waste after job. Prices are horribly high now everywhere,but plumbing can't be avoided,so their price point is adequate to area,but service is superb.

The heater wasn't producing enough heat during a time when the temperatures were really starting to go down. I thought it was due to wiring issues on my ecobee system. A tech came out, looked at the wiring, and proceeded to work on the system down stairs. Apparently it was due to the refrigerant being low. Had no idea, that refrigerant was needed to produce heat. All in all, it was fixed and was done quickly. Not sure how the price compares but I think it was fair.

This past week we had a part failure on our heat pump, and Mike personally walked us through various troubleshooting procedures over the phone before coming by to examine the unit in person. He ended up ordering a replacement part, coming back the next day and spending over an hour installing it and ensuring it was working properly. And for all this work, four years after installation? No charge at all. Mike has been in the business for years, and genuinely sees his customers as valuable, long-term relationships. It's borderline incredible that in an era where seemingly everyone in the universe is out to nickel and dime you for every little thing, people like Mike are still putting in the work. Could not recommend them more.

Our remodel started in July and after multiple days of no-shows, people walking off the job, and lack of quality work to include them installing used electrical outlets, unprofessional project manager and finally abandonment of project by them never returning to finish work and then never communicating with us about a walk through, we have a new contractor taking over the job 6 months later. Beyond frustrating! I give two stars because the tile guy did a nice job and the plumber was kind. Lesson learned- Do Not use a big box store for a remodel and don't use Nichols and Phipps for remodeling work.

Like all HVAC companies I have had the misfortune to encounter, a service contract means squat when…read moreit comes to what they charge. If it is cold out and your heat is off, you'll pay just about anything, and they count on that. Between the 35% markup on parts, charging to go pick up your part, and the supposed "contract" rate on the labor, you'd better just get ready to PAY. You'd be better off making sure there's an HVAC guy in your family! I can buy the parts cheaper than they supposedly can! CFS ate up FWHarris, our original installer, and they were great. I would LOVE to find an honest HVAC company that will charge me fairly and not a "book" rate. They tried to tell me I got a deal because they could have charged me $200.00 more! This time I watched him, and the next time that part needs to be replaced......

He had enjoyed a long history of clients who used this company with consistent success. I am very happy that I took his advice! The CFS technician arrived promptly and was able to make the repair. He was highly knowledgeable and took the time to fully explain the problem to me. He did not try to sell me anything, but he did confirm my fear, that my 28 year old unit was barely hanging on. As a result of his exceptional customer service, honesty and knowledge, I requested and received a very fair quote and had my new unit installed that following day. The service technicians were quality individuals through and through and could not have been any nicer and respectful of me and my home. Once the work was complete, my old unit was removed and they swept and cleaned the inside floor and my back yard patio. When you are calling around looking for the best deal and weighing all aspects of choosing a HVAC company, I highly recommend you choose CFS for their exceptional customer service, honesty, integrity, and quality workmanship. You will be so happy you did!!!

They said we'd need a new part and they'd overnight it and they'd be here first thing tomorrow. Tomorrow rolls around...no phone call...so we called them. Our part wasn't shipped so they said they'd come first thing the next day. Again, we had to call them to find out.

Thea, the owner / service manager, came out to inspect our AC system and immediately noticed something dangerous: the previous installer had set up the outdoor disconnect without a fuse, which is a major safety issue. Because of that, the wiring had burned and nearly made its way into the house. T patiently explained everything to me--what went wrong, why it was dangerous, and what the proper setup should be. He recommended replacing the disconnect with a fused version, and clearly laid out the potential risks and what to expect. When we turned the system back on, we were holding our breath... and to our relief, the 10-year-old compressor kicked on just fine. T could have easily told me I needed a whole new unit, but instead, he was honest, transparent, and incredibly knowledgeable. I even looked up everything he explained afterward--and it all checked out. By the way, the communication was excellent--I reached out through Yelp and was kept in the loop with email reminders and messaging right through the app. Everything felt smooth and professional from start to finish. In the attached photos, you can see the burnt wiring and connector from before, and the new fused disconnect they installed. The difference is night and day. If you want HVAC work done right, by people who take the time to do things safely and explain them clearly, TC HVAC Services is the team to call. I thought the cost for the service was very fair, and I'm really glad I found them.

The unit was dated so they recommended a new HVAC system. Their prices are reasonable and close to what others proposed.

I would recommend them for repairs and system upgrades if you are in need. Be sure to include TC for HVAC system replacement quotes.

Prior to working with Mr. Brown, we had unfortunately experienced several unsuccessful attempts to resolve our AC issue, previously installed by a GC, including misdiagnoses from other contractors. From our first interaction, Mr. Brown distinguished himself through his professionalism, technical expertise, timeliness and genuine commitment to finding the right solution. What truly set Mr. Brown apart was his deep understanding of what the company's brand represents. He approached our service call not merely as a transaction, but as an opportunity to build trust and deliver. His dedication to quality workmanship and customer care has left a lasting impression on us. I can honestly say that because of our experience with Mr. Brown, we now have an immediate positive association whenever we see Brennans logo. This is the kind of brand loyalty that cannot be bought it can only be earned through the exceptional work of employees like him. As a direct result of this experience, we plan to enroll in your maintenance packages for all future service needs and have already recommended both Mr. Brown and your company to several friends and acquaintances who have inquired about reliable service providers within our HOA listserv.
