HVAC reviews in Hayward, California

We just had a Mitsubishi heat pump system and a heat pump water heater installed in our home in Hayward by Villquin Air Services, and the experience was outstanding from start to finish. Beto, Luis, and AJ were incredible to work with—professional, knowledgeable, and genuinely helpful every step of the way.

One thing we really appreciated is that Villquin is licensed in both HVAC and electrical. They were able to install a dedicated electrical circuit for a future EV charger at the same time, which saved us from having to hire multiple contractors. That convenience alone was huge, and everything was done cleanly, efficiently, and to a very high standard.

The team took the time to explain options, answer questions, and make sure everything was done right. We’re extremely happy with the system and the service, and Villquin Air Services will absolutely be our preferred HVAC provider going forward. Highly recommend them to anyone considering heat pumps, water heaters, or home upgrades.

I had an excellent experience with Villquin Air Services installing my new Mitsubishi heat pump and mini-split multi-zone system. From start to finish, their communication was outstanding—clear, timely, and professional, which made the entire process smooth and stress-free.

They were punctual, showed up exactly as scheduled, and treated my home with great care. The team maintained exceptional cleanliness throughout the installation and left everything neat and spotless once the job was completed.

Their pricing was fair and transparent, and the quality of the workmanship truly reflects their expertise and attention to detail. I also really appreciated that Villquin Air Services is a Go Green contractor, making it easy to choose an energy-efficient Mitsubishi system. The financing option they offered was straightforward and extremely helpful, making the upgrade affordable and convenient.

The system is performing flawlessly and has already made a noticeable improvement in comfort and efficiency. If you’re looking for a reliable, honest, and highly professional HVAC company, I highly recommend Villquin Air Services. Top-notch work and customer service!

Solid company. Employees and owners know what they are doing .

Great experience everytime i visit i feel very satisfied.

Awesome place to work for the entire staff & very knowledgeable service technicians that are at their best very professional I recommend them to anybody package unit Pros total HVAC experience

Your driver is unsafe. He pulled into parking way fast. Also cut me off while I was backing out. This was at RSD in Rancho Cordova. License plate number 23854B1.

Hoping to get the attention of someone. My business suffered from not having AC all weekend. Tech came out on Thursday and said they couldn’t figure it out. I desperately need my AC fixed.

Package Unit Pros did HVAC maintenance services for us. They were accountable, and their staff was very helpful and responsive. I would definitely use them again when we need this type of service.

This place shouldn't have a star at all. What a joke of a Co. They steal from their own employees. And when the owners mess up they hide from their client. Very childish. Their customers come to their business address only to find out that they just left after they mess up on pretty much all their jobs that they personally sell only to blame the tech for their failures

Trustworthy. I was already moving forward with a $9k project with them, but the person in charge of my project reviewed my plans and recommended a different route, which will probably SAVE ME $8k (will update review if untrue). They've done other HVAC work for me, and the techs are always professional and competent, but this level of INTEGRITY had to be made known. They deserve my business, and then some.
