HVAC reviews in Commerce, California

I was very impressed with David’s professionalism and customer service. He met with my husband and I that same day we called and he helped us from beginning to end. He never missed a call. We got our reports sooner than expected. Thank you.

David is extremely knowledgeable and made the title 24 certification beyond easy for our build. Highly recommend his services.

Really impressed with the service from Gerhart Heating & Cooling. The technician showed up on time, explained everything clearly, and got my AC running perfectly again. Pricing was fair and there were no hidden charges. If you're in Commerce, CA and need reliable HVAC service, I’d definitely recommend them!

The technician arrived on time, explained the issue clearly, and fixed everything without trying to upsell anything unnecessary. I appreciated how respectful and tidy they were while working in my home. The pricing was fair, and the service felt genuinely reliable. It’s hard to find companies that are both professional and easy to deal with, but these guys did a great job. I’ll definitely be calling them again if needed.

Gerhart Heating & Cooling came out the same day, quickly identified the problem with my unit, and had it running efficiently again—the service was straightforward and dependable.

It​‍​‌‍​‍‌​‍​‌‍​‍‌ was not a good situation that I had to call for 24-hour HVAC repair late at night. Better, the response to the call was quick and professional. They fixed everything nicely and the comfort came back ​‍​‌‍​‍‌​‍​‌‍​‍‌immediately.

I​‍​‌‍​‍‌​‍​‌‍​‍‌ was able to escape my freezing house thanks to a same-day appointment for a heater repair service on the same day. The technicians were punctual, and the work was done in a very short time. Perfect service with instant results.

What I would praise most about the service of HVAC maintenance by this company is that I could not have been happier with it. The tech was fully knowledgeable, polite, and went the extra mile in his work. Now the unit is functioning as if it were brand-new.

My sister noticed warm air blowing in the middle of July, and that’s when she booked an AC replacement. The company removed the outdated condenser, upgraded the lines, and had everything running smoothly by evening. She said sleeping comfortably again made the whole process worth it.

Sold us a HVAC system but never followed up afterwards. Zero service at all.

This company's lack of attention to detail is staggering. The technician left exposed wires, my thermostat was haphazardly installed, and the system still fails to cool as it should. When I contacted the office, they were dismissive and unwilling to own up to their mistake. I ended up hiring another service to rectify the mess they left behind - avoid this company at all costs.

Jesus and his team did a great job on my Attic AC Unit's maintenance. The unit was leaking water, prompting me to take action. They fixed the issue and have performed annual maintenance every year since then. Additionally, they helped my neighbor with a minor problem that caused the system to stop working. A relatively inexpensive replacement part resolved the issue, which is what I got from their company. Overall, I'd say it's honest and reliable service.

The repair service for our AC worked flawlessly. The technician showed up promptly and efficiently fixed the issue, leaving us satisfied.

We prepped for the summer heat with their AC service, which paid off. They thoroughly cleaned the unit, checked the refrigerant levels, and now it's working great. We made a good choice; you won't regret using them either.

I've been working with this company for a couple of years and they've been a huge relief. When my air conditioning stopped working, they stepped in and fixed it quickly - their staff is very responsive and courteous.

This service is a must for keeping your home's furnace running smoothly - the technician was knowledgeable and thorough.

The technician arrived late without acknowledging the delay, gave a cursory inspection and departed. Later, the air conditioning started leaking water, prompting a call for assistance. They assured me it would be a new visit with an additional fee, but the underlying issue remained unresolved. The lackluster follow-up and attention to care left a bad impression.

The recent installation work was satisfactory, particularly in ensuring proper placement and safety checks were made during the process.

The service was hassle-free, with prompt responses from the company. A technician arrived promptly, diagnosed the problem quickly, and had my furnace up and running in no time.

The technician left a mess at my place, scattered tools and packaging everywhere. Despite saying the AC was fixed, it started blowing warm air again just hours later. I'm frustrated with paying for a service that doesn't deliver - very unprofessional and lacking attention to detail.
