Get matched with top thermostat installers and replacers in Harbor City, CA

"Trinity Heating installed a new thermostat in my house. The technician, Jimmy, was professional and courteous. After the installation he took the time to explain to me how to set up and use the new thermostat. I’m completely satisfied with their service and will use them again if needed."

"Service was great and pricing very competitive. Nick Knuth was very knowledgeable when he came to do an assessment of the work to be done, and answered all my questions I'm a very clear way. The techs worked pretty quickly and efficiently when installing the new unit. Deisy and Emma from the office always made sure that things were taken care of and went above and beyond with follow-ups and updates. I would definitely recommend them to anyone who needs this service."

"They were responsive and showed up to my mother's house as promised and repaired her thermostat."

"Fantastic. Felipe gave a comprehensive quote, performed the work on time as per our agreement, worked during the day without a ton of bother to me (I work from home) and his team was professional and respectful. They cleaned up after themselves every day and it was very easy to live in my house while work was being done. The drywall is gorgeous and the work I"m very happy with. This job was a lot of random things - moving plumbing, reframing walls, completely redoing the drywall, installing a window, removing and replacing a walkway, etc."

"Fast efficient service. Left the job area very clean. My only complaint is they don't provide a breakdown of the bill; parts/materials and labor costs. Not cheap, but their work is top notch."

Hello everyone. I have 8 years of professional experience in the workfield; I have been working in the air conditioning field since I arrived to this country. I strive to provide the highest quality work and service, and it would be a pleasure to assist you. I speak both languages, English and Spanish.

"I contacted Calculated Aire to replace my 30year old forced air furnace (natural gas). Edgar came out and talked thru the replacement options (whether I wanted AC, different furnace models and tonnage, etc). I decided to replace with a furnace of slightly larger capacity. Edgar procured all the materials and came back the next day. He removed the old furnace and installed the new one. He even had the good sense to install a filter housing (provides better seal for air filter and makes swaps easier). He also replaced my aging gas valve and installed a drip leg. His ductwork looked very clean as well. New heater was working within a few hours. Very happy with the service and cost. If I ever have any issues I'm calling Edgar direct."

"Joe was amazing. He not only found a better A/C unit than the one we we were looking at (for even less than what we had originally budgeted) he also installed it perfectly. When we had a small issue (turned out to be low FREON) Joe came, replaced a valve and fixed it perfectly. Our new A/C is working great and Joe has been amazing to deal with. We would hire him again in an instant."
