Reviews of local pros in Grass Valley, California

We're very happy with the replacement of our gas heater and electric AC done by GVAC one year ago. Big improvement on our energy bill, too. Professional, knowledgeable company who do exactly what they promise to do.

Employees were efficient, experienced, knowledgeable , polite, respectful. Cleaned up after finishing job. Would definitely recommend. I’m very happy with my tankless water system.

My previous experience with GVAC was great and they just finished updating my furnace and ductwork. Again, GVAC employees were respectful, knowledgeable, efficient and polite. They answered all of my questions and cleaned up when their work was done. I highly recommend them.

Grass Valley Air Conditioning (GVAC) provided excellent service. We hired GVAC to install a mini split heating and cooling unit. Rod, the owner gave us a prompt and competitive bid. David the technician who installed the system treated the project like he was installing it in his own home. He was thorough ,conscientious, and a true craftsman.
WeI are tough customers. The highest compliment we can pay is we are very happy with GVAC.

Great customer service. Grass Valley Air Conditioning was very responsive and kept me informed through out the entire process. They explained my different options and helped me choose the best furnace and air conditioning unit for my house.

I left a message on July 4 at 5pm because my air conditioner stopped working during a heat wave. I was called at 8:00 the next morning and someone came to my house that afternoon to fix my AC. I was impressed by their quick and efficient service. They also charged me a fair amount while other companies often take advantage of customers in times of need.

I had a great experience w/GVAC! Started with the office staff, who are phenomenal. Then Ryan came out to inspect a 30+ year-old system and provide options for replacement. Bob spent a ton of time explaining everything I could ever want to know about heating and air conditioning, to inform my decision. When I finally did decide on a packaged unit, they were super quick to schedule installation and complete the work. Really tidy job site, almost like they were never there -- except that the house was warm again! Big thanks to our HVAC "dream team."

Grass Valley AC is wonderful. I've been using them for years and then had a problem with my unit. A tech was sent out to my house quickly and discovered a problem which was under warranty. Owner Rod came out to assess the unit. Within a week I had a replacement unit which is even more efficient. Bob in the office coordinated the work and called me each day for an update. A tech even helped me to fix my fire place so I would have heat.

In the 5 years we have been using GVAC, whether it be repairs, installations or maintenance on our heating, air and hot water systems; the work has always been exceptional and the pricing fair.
We also appreciate the friendly service.
Thanks, Ann and Mike

Grass Valley Air was fantastic to work with. The install crew was fast and efficient. We love are new mini splits system

We had a mini-split system installed and it was no easy task--But GVAC handled it! Great communication throughout the entire process. Awesome people with amazing service + knowledge. Friendly, professional, and a total pleasure to work with.

I’ve been dealing with Ryan Jones for 15 years. He is extremely knowledgeable and professional. He is honest, shows up on time and does what he says.
Dave was the lead on the recent installation of my new Series 7 GSHP. He was excellent! He was professional and answered all my questions. He and Daryl had a very difficult installation location to deal with. They didn’t cut corners and did an excellent job.
The unit is purring like a kitten and using so much less energy than my old unit. I highly recommend Grass Valley AC

Very professional company. This was a rental to fix and ended up being a replacement. Replaced wall heater.

Absolutely do not recommend Grass Valley Air Conditioning.

Update: Thank you for your response, but it contains several inaccuracies and omits key facts:
1. No Call, No Consent: I was explicitly told by your staff that I would receive a call before any work beyond the $90 diagnostic was performed. That call never came. You performed and charged for services without my authorization, which violates what was agreed to during scheduling.
2. Tenant Not Authorized: My tenant was never authorized to approve work or sign off on charges to my credit card. He was under the impression that he was acknowledging a visit — not authorizing repairs or charges. There was no pricing or estimate on the document he signed. Calling it a “work order” after the fact doesn’t change that it was incomplete and misleading.
3. Admission of Fault: Your own representative (Rob) admitted in multiple phone calls that the technician failed to follow your internal procedures by not contacting me. He even stated the technician was reprimanded for that failure. That alone confirms your technician acted outside the bounds of proper conduct. I never received a phone call from said owner.
4. Dispute Still Unresolved: I requested a reasonable compromise: I offered to pay for the diagnostic ($90) and $22 for the minor work, but you declined and charged the full $229. Saying that Square “upheld” the charge only means it was processed — not that it was justified.
5. Mischaracterization of the Issue: Framing this as a heroic effort during freezing temperatures is misleading. The issue is not whether the technician turned the heat back on — the issue is that I was never asked or informed before you charged me for it.

I made multiple good-faith efforts to resolve this with you privately. Your refusal to take responsibility or offer even a partial refund shows a lack of accountability. I stand by my review and encourage others to be cautious.

I talked to Cory and scheduled a $90 diagnostic for my rental property and was assured I’d be contacted before any additional work. They broke that verbal contract.

The technician arrived without calling, performed unauthorized work, and charged my credit card $229 without my consent. My tenant, who is not authorized to make decisions, was pressured into signing a document with no pricing (zero estimate for services). This is bad business.

When I called to dispute the charge, they admitted their technician failed to follow procedures and that no authorization was given for the service to be done. Still, they refused to offer a refund for the unauthorized portion. They were in the wrong and had zero accountability for it.

If you value communication, integrity, and consent before charges — stay away from this business.

We added a 2 room, single compressor Mitsubishi mini-split system. We were tired of heating/cooling the entire house for the sake of a a couple of rooms.

This was one my rare household upgrade projects that went smoothly. The price was fair, the 12 year warranty a plus, and the Mitsubishi mini-split is very quiet and fast. GVAC sales and installation personnel were professional and provided the training we needed.

I highly recommend the Kumo Cloud WiFi upgrade if you want remote programmability.

The Team was professional and courteous. The estimator who came out was thorough and respectful. The installation team kept the Jobsite safe and clean of debris. The Lennox System is awesome. We started saving $100 - $200 a month on Pg&e. Well worth the investment. Thank You!

We have had professional & excellent service on our older hearing & air condition unit. We had a recent emergency call, during snowstorm and Ryan came out & carefully fixed the problem & addressed all of our questions in a very clear manner. We are so glad we chose them & no doubt, will again.

I've had an amazing 25 years of exceptional service from GVAC. I trust the team to work for my satisfaction and comfort explicitly and am always charged a very fare service fee. I love my 25 year old gas furnace I bought from them, and then added electric splitters for my business needs. I can always count on the GVAC to be available for yearly maintenence and the few service calls that were needed (I think there were 2 total). Great teamwork from a local company that still cares to care for the customer! You are truly the BEST 🌹
