Get matched with top central a/c service or repairers in Robbins, CA

"We have been using Golden Aire for maintenance and repairs for the past 8 years. They are professional, knowledgeable and courteous, as well as fair in their pricing. Case in point, we had Daniel come out to do our summer A/C maintenance. Daniel discovered that coils were bad and leaking coolant. We received our quote for the parts and repair. The cost was estimated at $3k (ouch!) Parts were ordered and Daniel came out within a weeks' time. I can't state highly enough how impressed we were with Daniel's knowledge, professionalism and most importantly care. Daniel was able to save us $1,300 as he discovered that after fixing the Nitrogen leak and replacing the refrigerant there was no need to replace the coils. I know other less scrupulous companies would have milked us for a higher invoice price especially since the coils were ordered. Thank you, Daniel, and Golden Aire for your honesty and professionalism."

"They installed central heating and air in our home in 2025. They were efficient, did a excellent clean up, and friendly. They checked in a week after to make sure we were satisfied with the system and if we had any questions. We are extremely satisfied with the new system. The controls are easy to work and the system is very quiet and efficient."

"Same day service, appreciated! Fixed our AC quickly and affordably. Would definitely call again if there are any problems. Thank you!"

"I own a business and had a company come out to fix our air conditioner. They came out 4 times, charged for all those time and the unit still was not working properly. I then decided to try someone else, so I called Thermotech on the referral of a friend. They came out, diagnosed the problem within 10 minutes (it was an old crumbling circuit board), showed me that bad part, ordered it and had it fixed in less than 24 hours. We have not had a single problem since! I was so happy with their service that I ended up using them for my home HVAC system.. I even referred them to a family member and they did a home install of a brand new HVAC system and they were very happy with the price, install, workmanship & fair pricing. Thermotech has found a customer for life with me. I have had so many bad experiences over the years with other companies telling & thermotech has been a game changer."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"Our Service Tech, Alex Peck, arrived on time to perform the annual check up & tune-up of our HVAC System. He was very professional and following the Tune-Up asked if there was any other items that needed done or looked into that he could take care of. His services were very much appreciated and very professional. Lee"

"We reluctantly conclude that dealing with Park Mechanical and Lennox has been an expensive mistake for us. In July 2013 we signed an “investment agreement” with Park to install a new Lennox furnace and air conditioning system in our house, to replace the old system, at a cost of over $10,000. Then we learned that the five-year Lennox warranty would be good only if we paid Park to inspect our system periodically, to certify that it has been “properly maintained.” To accomplish this we were persuaded to join a Park program called the “Shamrock Club,” under which we have been paying Park $99 a year for periodic inspections to certify that the equipment still qualifies for warranty coverage. One such inspection, in January 2016, declared the system to be correct and operational. But in May 2016, when the first hot weather arrived and we turned on the air conditioning, it did not work; there was no cooling. A Park technician found that something called the TXV valve had failed. After several hot days waiting for the replacement part, the valve was replaced and the system worked again. The repair was considered a warranty issue, and we were not charged. Similarly, on March 28, 2017, a Park technician inspected the system, found it to be functioning normally, and declared it to be “on maintenance.” At the beginning of May 2017, however, when the weather turned warm and we turned the system to “Cool,” it failed again. A Park technician found that all the refrigerant had leaked out, and refilled it pending permanent repair of the leak. On May 15 the technician returned and told us we would be charged $238 for the refrigerant and additionally for the labor to fix the leak. This time we learned that the Lennox warranty covers only the parts themselves that fail, and not the labor or the refrigerant needed due to the failure. No leak was found, and we were informed that the next step would be to inject a florescent marker dye into the refrigerant to show the leak – at an additional cost to us of $395. This failure is due to a failure in Park’s workmanship or in the Lennox equipment itself. The cost to fix it should be covered by warranty. Our disappointment with Park also includes Lennox, which offers only minimal warranty coverage for its products. Our experience may indicate why the company has so little confidence in what it sells. Our specific issues are: 1) Having to pay extra for warranty coverage on expensive new Lennox equipment. 2) The warranty does not cover labor and other costs that are likely when warranted equipment fails. 3) Our Lennox system has failed twice in the space of a year. This is not acceptable reliability. 4) Every Park inspection of our system has declared it to be operational and adequately maintained, including those immediately before the two equipment failures."
