HVAC reviews in Sunnyvale, California

When our heating system started acting up, it was a major hassle, but they treated our situation like a priority. They gave us a clear, reasonable estimate before starting any work, which we really appreciated. The Balcom team showed up on time, stayed in touch, and explained everything in a way that was easy to understand.

They’ve become our go-to for dependable HVAC service and maintenance. It’s clear they care about keeping our home comfortable all year long, and we were happy to leave the tough work in their hands.

The technician handled everything efficiently, made sure the system was clean, and checked that everything was running properly before leaving. It’s reassuring to know we can count on them whenever we need help.

I went to start our AC unit and it wasn’t working. I gave them a call and they came out in a timely manner and got my AC working right before summer comes. The Balcom team was easy to work with, knowledge, and professional. I would recommend them for any HVAC needs.

Very knowledgeable, prompt, professional and very reasonable.

Great service, they care and do what it takes to fix the problem!

Was very responsive, even though he was extremely busy. Very helpful and happy with service and price.

It’s always a pleasure working with Carlos .

High recommendation with patience they explained the operation and adjustment of our system. They answered our questions and offered future help if necessary. A profound experience.

Service was professional and timely. No issues with Balcom's work. They have installed and maintained our gas furnace and A/C units for years.

I called in the late morning and by mid-afternoon Carlos had fixed my AC unit. He was very efficient and professional. I will be recommending Balcom Heating and Air to anyone I know with HVAC issues.

Carlos and his team are absolutely amazing! They did our new ducting for adu and wall mount heater removal. Detail oriented and very professional. Highly recommend using them for your hvac solution!

Balcom Heating and his team are very Professional and extremely knowledgeable. They installed 2 new AC units in my home and I am pleased and happy! Also very affordable and reasonable.
Thank You Carlos and Team

Carlos is awesome! He showed up to fix the AC unit on an 106F degree day after working 12 hours already. He was professional and reasonably priced. My appointment was his last one of the day, but he went above and beyond to troubleshoot my neighbor’s AC issues too. Highly recommend!

Absolutely amazing service! Carlos is honest, extremely competent and genuinely cares about doing the best job possible. We are so happy with the communication, the service, the price and most of all...our gas furnace heater is fixed! (after days of run-aroiund with other companies) Carlos went above and beyond to help us. We could not recommend Balcom Heating and Air enough. The best in the business!

I was really impressed with Balcom Heating and Air. Our heater broke right in the middle of a cold snap. They came out quickly and were able to diagnose that the circuit board was malfunctioning. They ordered and installed a new board in less than 24 hours and we have heat again! Carlos and Alex are great! Highly recommended.

The team at Balcom have done an amazing job making sure the units in our building are running in the best shape possible. We’ve had a couple emergency situations and Balcom has always shown up fast and done the job right the first time.

The HVAC sanitization service was worth every penny. The air in my home feels noticeably fresher and cleaner. The team was punctual, professional, and very thorough. They explained every step and answered all my questions. I’m so glad I chose them for this service. Highly recommended for anyone looking to improve indoor air quality!

The crew did a great job. The new system makes our house cool and comfy.

Their HVAC installation service was fantastic for me. The workers were pleasant and knew what they were doing. They finished the task fast. The system works flawlessly. Very happy.

It was a big comfort to have this HVAC expert put in my new heating system. The HVAC contractor performed a great job, finishing on schedule and without any errors. The procedure works really well.

I have had the pleasure of working with this company for my thermostat repair needs and I must say, they are absolutely top-notch.

This AC company did a great job installing my new AC. They were very quick, efficient and courteous.
