**BEWARE -- DO NOT HIRE THIS COMPANY!** I strongly recommend thinking twice before hiring this company. There were so many problems with both the installation and the owner's conduct that it would take several pages to explain everything that happened. The installation was quoted as a one-day job but ended up taking three days. The work area was left in the condition shown in the photos. They completely destroyed the trim, door, and door frame. After the third day, they simply said they were finished and left everything completely trashed. When I did not immediately pay the full balance the moment the crew finished, I began receiving repeated phone calls and demands for payment. Only a couple of hours after the work was completed, the owner, David, came to my home late at night and continued knocking until I answered. He then confronted me at my front door, yelling and swearing while demanding his money. His behavior was aggressive, intimidating, and completely unacceptable. The following day, I began inspecting the system and immediately found problems throughout the installation. The filter was approximately half the size it should have been. They installed a 1-inch-thick filter even though the filter compartment was designed for a 4-inch filter. They also reused my old filter compartment, which did not properly line up with the blower unit, so they covered everything with an excessive amount of tape. When I attempted to remove the filter, I discovered that the filter door could only open a few inches because they had installed the overflow drain and S-trap directly in front of it. This is basic HVAC installation and common sense. In my opinion, it was a perfect example of the company not caring about performing decent-quality work. The overflow safety switch was also missing. The attic insulation had been pushed completely to the side and was never put back, and the surrounding trim was badly damaged. These were only some of the issues I discovered. The company had to return three separate times to correct problems. Approximately one week after the installation, the unit stopped working entirely. This happened during one of the coldest stretches of the winter, leaving us without reliable heat for approximately 10 days. We were forced to purchase several portable heaters just to keep the house warm. The system also failed its inspection and failed the HERS test twice. Problems related to this installation continued for approximately six to nine months. Throughout the dispute, David repeatedly contacted me at work, sometimes calling 30 to 40 times within a single hour. He contacted my boss, left messages on my work phone, and even emailed my employer accusing me of defrauding him. He also threatened me with bodily harm on more than one occasion and made statements suggesting that I should be afraid of him because of his alleged special operations military background. In hindsight, I should have contacted law enforcement and pursued legal action. Instead, I ultimately just wanted the situation resolved so I could have no further contact with him. Based on the poor workmanship, repeated installation failures, failed inspections, aggressive collection tactics, workplace harassment, and threats I personally experienced, I cannot recommend this company. read more

Frustrated and disappointed, I don't even know where to begin when talking about this company we hired them to install a new furnace and AC unit for $9,000. Everything seemed fine at first, but once my wife made the mistake of paying them before the job was fully completed, their behavior changed. The thermostat was malfunctioning, causing our home to feel like a sauna. I tried contacting them for help, but they were unresponsive, claiming they were busy watching a movie with their daughter. In desperation, I had to figure out the issue myself and ended up having to turn off the thermostat with a flashlight from the circuit board. To make matters worse, they flaked on another appointment and blamed it on us not confirming, even though there was no mention of confirmation in the email. It's clear that this company and their unacceptable behavior should be avoided at all costs. I can't help but wonder if David is dealing with drug a or gambling issues. Needless to say, we will never be using their services again. read more

I called David and asked if he would look at my heater which was not working. He said yes, but he was all the way down in San Mateo, and said that traffic was going to delay him. He arrived at my home in Vacaville just after 6 pm, and I was worried about the cost at that time of day, but without a working heater I would just have to bite the bullet and pay whatever he charged. He got to work, and he knew exactly what was wrong, and had it fixed within a half hour. One of the gas jets was plugged. After putting it back together and testing it, it worked like new. Then I was at the point where I asked how much I owed him, and he replied nothing. He said the repair was quick and easy for him so he didn't feel the need to charge me for it. Bottom line; David Rendon has a grateful customer, and when I need something done in the future, I know who to call. read more

Just want to give a shout out to Rendon Heating & Air. Called them yesterday at 1:37pm to see if they could come take a look at our AC unit which was turning on and not blowing any cold air. The company I have a monthly contract with to do our biannual inspections on our AC & furnace units couldn't come out till next Wednesday. That just did not suit our need. Rendon made us an appointment for the same day. Lupe was our technician and he was awesome. He diagnosed the exact problem so quickly and was able to acquire a new AC capacitor in no time and we were up and running with cool air by 6pm. They also give a military discount so that was much appreciated. Thanks again for their prompt and professional service and I will definitely recommend to give them a try if you have any issues in your home. read more

Rendon Heating & Air is nothing short of EXCELLENT! We had 2 local companies come out to service our AC as it was not working. Neither company was capable of fixing it and recommending replacing it. Rendon came to our rescue as we are not yet able to afford a new unit immediately. David was patient, thorough, and extremely knowledgeable in explaining the issue we were experiencing. We are so thankful for this local company and being that he is a Veteran was only a bonus. Rendon Heating & Air, will replace our system next year and they will be the only company that we will call from now on! Trust in them, you will not be disappointed. read more

We won't go into details but all we can say is that David is D best! Told him he was such a blessing sent to us! I spoke to 4 different companies before I spoke to him. I know no such thing as perfect but he was perfect to us! He got to our house like in minutes and fixed our AC in minutes! He even helped us with something not related with AC and with no charge for the consultation. Didn't meet his wife but got to chat with her via text and she was awesome as well! Would highly recommend David, Rendon Heating & Air! Thank you David and Melissa!! Take care, Victoria read more

We had such a great experience with Rendon heating & Air. From start the finish, David (owner) was incredibly friendly, honest, and easy to work with. He took the time to explain everything clearly, wasn't pushy, and never tried to up-sell us on anything we didn't need, which we really appreciated. Our new heat pump is no only beautiful, but its also super quiet and already helping us save money on our energy bills. The install team was excellent! Professional, clean, and respectful to our home. You won't be disappointed if you go with Rendon! read more

We had a new HVAC system installed by Rendons Heating and air and they did a great job. The owner was very attentive and communicated with me about all the forms that needed to be signed via the computer and helped me qualify for the Go Green Loan. His technicians were very efficient and courteous and did an excellent job installing the unit. They scheduled a five day follow up to come out and make sure everything is working properly and I thought that was great service. Thank you so much. Estepa , C read more

Highly recommend Rendon Heating and Air for heater install. The pricing was better than anyone else we called. You can feel the care of a local family business in everything they do. They went the extra mile to install something cool that makes it easier to swap out filters as a little bonus surprise. BECAUSE THEY CARE ABOUT LONGEVITY. Vacaville, Solano County: go with these guys. Best VALUE (and you'll love their Jeep Truck too!) read more

God Bless You and your business, I know you will succeed. read more
