"The tankless water heater installation at our Oakland home has been fantastic so far. We finally have enough hot water for the whole family without constantly waiting between showers. Dan completed the installation quickly and explained how everything worked before leaving."

"WOW! Fast response. Came out on the 4th of July. Diagnosed the problem, gave me options, very good communications. Needed to replace the air conditioning unit. Went above and beyond to fix insulation, vents, as well as the unit. Very fair price. Immediate communications. Sammy and Alex are great. So is Jose. I strongly recommend Blueberry. They will be coming out in a couple of months to replace my 40 year old heating units. I'm so happy I found them. Strongly recommend."

"This HVAC company is honest and professional, definitely the one to hire. I had another company replace my A/C units last summer and level the furnace, but the system broke down after 6 months. There were several parts of the system that they failed to repair or even inform me about. Reese spent the time to give me a fair and accurate estimate, and even encouraged me to get other estimates before hiring them! Lance the installer came out to replace my old furnace and repair a few parts of the A/C system that had been slapped together, but he went above and beyond to expand my attic access, improve the drainage and bring the whole system up to code. The A/C and heating work great now, and my family and I feel safer knowing that Lance put in the extra time to carefully check everything."

"Mike Alamillo was a wonderful person! I pestered him for prices and model numbers for HVAC equipment and he patiently supplied me with information. (I suggest that we customers do our research before we pester contractors. ;-)) He and his crew were very polite, very professional, and did an outstanding job. I'd recommend SW Heating & AC to anyone!"

"Replaced my gas furnace and air conditioner with a heat pump. The only company I contacted who did a thorough analysis of my home and electrical system to determine exactly what I needed. Side note: I requested this service because my furnace quit working. The technician who came out to evaluate my home repaired the furnace for free while doing his analysis. I still bought the heat pump, but this company definitely did not simply try to just sell me one."

"Season Control installed our AC fast and efficiently! We had 3 other estimates and all of them complained it was going to be a hard job and take 5 days at least. Season Control gave us a fair estimate, never complained and the job was done in 1 1/2 days as they said! They followed up afterwords to be sure we had our AC and Heater serviced on time and did an excellent job of that as well. It is nice to have a company do the job and do it well without complaining!!! I will continue to use them for future needs!"

"He called to see if it was ok if he came EARLY (!) We thought it was time to completely replace our old AC, and were prepared to be "nudged" in that direction. But he cleaned it, did some minor fixes, and advised my husband on maintenance. He was gone before the orig. appt. time and our AC has never worked better!"

"Victor is a very knowledgeable person. He was able to stop a leak on my furnace on a very tight spot, I believe others would have given up on that job or perhaps charge extra for it. He was able fix it. Victor showed up on time and ready to work. I would highly recommend Victor."
