I needed to get my HVAC system replaced for my house, so I sent out a couple of requests via Yelp…read morefor quotes from highly rated service providers in the surrounding area. Paul, the owner from MechPros HVAC came over the weekend to do the assessment and consultation. It was very helpful be able to do it over the weekend so I didn't have to take time off from work. He was on time, communicated well, and very thorough. Among the half a dozen vendors I contacted, he was among the few that truly listened to my input instead of trying to upsell or push options I wasn't interested in. After comparing all the quotes, MechPros' quote was very competitive. I decided to go with them and scheduled the job which was able to start quickly in about a week after signing the contract. On the scheduled day, Will and Kieran, the two installation crew members, arrived right on time. They were courteous, personable, and professional, and did a good job. They kept the job site clean and neat with drop clothes with minimum disruption. After two days of work, the installation was done. They cleaned up nicely, took away all the disposable materials, and restored everything back to where things were. The installation job was done very neatly in the attic and backyard. I can tell they are proud of their work too. The new system is much better than the system it replaced. After the system started up, I noticed some issues. Paul was very responsive and sent a technician immediately to check it out. After a repair that wasn't successful, he personally came out and concluded that the issue was related to the equipment. Paul took responsibility and ownership of addressing the equipment problem under warranty with the manufacturer. He sped up the resolution by fronting the cost of providing replacement components and dealing with the warranty replacement parts separately to reduce the system down time. I appreciate MechPros HVAC and Paul for taking ownership and having customer service as a top priority. After the problem was resolved, MechPros also helped coordinate the city inspection to secure the final permit approval. I would not hesitate to recommend MechPros HVAC for anyone who needs HVAC system services.

We also appreciated that the owner (Ian and Jason) was personally involved in the installation. Their dedication was impressive--they worked through a heatwave and even stayed overtime to get our AC running as soon as possible when they see how miserable we were during the heatwave. The workmanship was excellent, with minimal damage to our home, and they left everything clean and tidy. It's rare to find a company this honest, hardworking, and detail-oriented. Highly recommend!

I recently had an extremely disappointing experience with Hometown Heating and Air Conditioning. My…read moreair conditioner was not cooling, although the fan was running, so I called their customer service to request a diagnostic report. I clearly stated that I needed a diagnosis and a report on the issue. The technician arrived the same day and initially seemed nice. However, he started asking personal questions which were unrelated to the job. During his diagnosis, he identified the problem as a faulty capacitor and replaced it, charging me $400 for the part. This price seemed excessive, especially since a relative of mine had a similar issue resolved for only $200. When I questioned the price, he insisted that the company charges $400 and refused to offer any discount. I also found that the same capacitor costs merely $20 on Amazon. When I declined to replace the capacitor at such a high cost and reminded him that I had only requested a diagnostic report, the technician became angry. He even threw an object in frustration, luckily he didnt throw it at me. I asked him to calm down and reminded that i would pay the $80 diagnostic fee, but he continued to murmur angrily and then put back the old capacitor, and left. After he left, I found that the thermostat, which was working before, no longer turns on. I also discovered that the circuit breaker panel was left open and disconnected. When I called customer support to have the technician return, they informed me that the technician was upset because I did not purchase the capacitor and would only come back if I agreed to pay for it. This response was unprofessional and unacceptable. The customer representative promised to send another technician the next day but also told me not to call their company for any future issues, which was very surprising and unprofessional. The next day, there was no follow-up call, and when I reached out again, the supervisor refused to send a technician unless I agreed to their repair terms at a hefty price. I was advised by the supervisor to handle the circuit breaker issue myself, which I reluctantly did, but the thermostat still did not work. The supervisor then stated it was not their problem and refused further assistance. Overall, this was a terrible experience with Hometown Heating and Air Conditioning. The technician's behavior was unprofessional, the customer service was unhelpful, and the supervisor was unsympathetic. I would not recommend this company to anyone due to their poor service and unprofessional conduct.

From the beginning, Daniel and his team were professional, honest, and easy to work with. They arrived exactly on time, and it was obvious they had a great deal of experience. The installation was done carefully, and the workmanship was excellent. What impressed me the most was that Daniel always did what he promised. He patiently answered my questions, was willing to help whenever I had concerns, and never made me feel rushed. Everyone on the team was polite, respectful, and took great care to protect my home during the installation. It's refreshing to work with a contractor who truly cares about quality and customer satisfaction.

Worth Every Penny…read more After being without A/C for three weeks, I was dreading the call. I had heard plenty of horror stories about HVAC companies, and I was hesitant when I learned there was a fee just to have a technician come out and evaluate the system. But it was absolutely worth it. Peter was fantastic--professional, thorough, and honest. He carefully checked the system, made the needed repair, and corrected a part that had been installed incorrectly. I was convinced we were looking at a $5,000 to $15,000 compressor replacement, so I was incredibly relieved when the total came to under $300. We now have cold air again, and I could not be happier with the service. I would definitely recommend them to anyone who needs an HVAC company they can trust.

He was thorough, even recording videos of his initial inspection so that we had a record. I especially appreciated that he called out Alameda regulations that were going to change in 2029 (this informed our decision to go with a heat pump now) On the day of the installation, we had an amazing experience working with Sam, Benny, Jesus, and Jorge. They were always very thoughtful and polite. Anything that might deviate from the original quote, they would give us a headsup. For example, they noticed that one of the pipes looked missing from the outlet in the yard, and that they would just charge us for parts if they needed to go out to buy a pipe and install it. Fortunately, the pipe was just hidden. They even went out of their way to help us fix one of our broken stairway steps. It was an incredibly smooth process, and we LOVE how quiet the heat pump is.
