Get matched with top central a/c installers in Alameda, CA

"Perfect Star is a top notch company with top notch personnel. I had my home HVAC system completely replaced and, from start to finish, Perfect Star provided outstanding service. The sales rep, Enrique, took the time to understand my current issues and concerns and offered viable solutions. The Perfect Star Install Manager, David, also inspected our system to confirm the right solution would be in place even prior to ever signing a contract. The Installation Team of Austin, Emanuel and Ray provided a through and professional installation. David, the Install Manager, was once again also on the scene to lend his expertise to the installation. I strongly recommend this company for any of your HVAC needs. Perfect Star is honest, professional, offers competitive pricing and are the best experts in their field."

"The installation technicians were on time and performed our installation in a very professional manner. They informed me of the installation progress and were very cordial."

"Great. They contacted me right away. It wasn't an emergency but Iti was cold, so they still came first thing on the first business day. The technician explained what he was doing and why the prior repair done by somebody else probably failed. The rate was reasonable. It's been a couple of days and it seems the furnace is working, so everything good so far."

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"Very straightforward and honest company. Sewer repair project was to run over budget due to factors not anticipated. However, true to their word, they honored the original quote for the work to be done. Work was completed very professionally with good quality. Would definitely recommend highly."

"Albert Nahman installed our heat pump last year and they do the maintenance twice a year. The technicians are prompt, respectful of our home, and do a thorough inspection. We would definitely recommend them!"
