A Rendon Heating & Air technician works on a customer's HVAC system.

Rendon Heating & Air, Inc. provides a variety of HVAC services for residential and commercial clients in Napa, Solano, Yolo, and Contra Costa Counties. The veteran-owned company has the in-house capabilities to install, repair, and maintain everything from central heating and cooling systems to specialized products like zone control systems and ductless mini splits, and its technicians are available 24/7 to handle emergencies.

Owner David Rendon credits much of Rendon Heating & Air’s success to its ability to quickly and efficiently solve all types of HVAC issues. “Troubleshooting is our favorite part of the job,” he affirms. “When a customer doesn’t have heating or cooling, we love being the ones to get their systems back up and running. There’s nothing better than seeing their relief when everything is working again.”

Rendon Heating & Air is known for its commitment to customer education. “Our clients really appreciate how much time we take to explain our work,” says Mr. Rendon. “Before we leave a jobsite, we make sure the customer understands how to use their system properly and keep it maintained for optimal performance. Ultimately, we want them to feel confident and informed about their HVAC investment.”

“Our customers are very important to us, so we focus on providing them with maximum indoor comfort at a great value. We want them to think of us for all of their heating and cooling needs, and by approaching each job with honesty and drawing upon our wide-ranging expertise, we’re able to earn their loyalty.”

What recent refrigerant changes mean for your HVAC system.
If you’ve heard about refrigerant changes but aren’t quite sure what they mean for your HVAC system, you’re not alone. The rules around refrigerants are changing, and while it all might sound ultra-technical, understanding the basics can help you avoid surprises.

What to know about refrigerants
Refrigerants are gases that help your air conditioner cool your home. For years, R-22 (commonly known as Freon) was the industry standard, but states like California phased it out because of its harmful effects on the environment. Now, R-410A, which replaced R-22, is also being phased out to make way for even more environmentally-friendly options with lower global warming potential.

If your HVAC system still uses Freon, you know it’s already difficult and expensive to find replacement refrigerant. HVAC units that use R-410A still have a little more time, but eventually, repairs and recharges will become more difficult and costly as supplies dwindle.

Upgrade your system to get ahead of the refrigerant rush.
If your HVAC unit is more than 15 years old, it likely uses R-22 refrigerant. If that’s the case, consider upgrading. If you have a Freon-powered system, replacing it sooner rather than later will save you from expensive repairs and refrigerant costs down the road. If your system is still in good repair, or if your system takes R-410A refrigerant, start saving now for a new system so there’s less sticker shock when it’s time to get an eco-friendlier unit.

A quality HVAC company can help you decide when to replace your system or when to hold off. Professionals can also give you advice on which new systems are best to invest in and which new refrigerants are likely to be cleaner and stay on the market longer.

Maintaining customer satisfaction is a key focus of any successful business, but it’s even more important for HVAC contractors that have earned Diamond Certified. For Rendon Heating & Air, Inc., keeping clients happy comes down to three main factors: arriving quickly, doing the job correctly and making sure they’re completely satisfied. “Helping people stay comfortable is the biggest part of our job,” says owner David Rendon. “In fact, we’re so dedicated to service that we schedule a free quality control inspection four weeks after every installation, just to make sure everything is working right.”

Rendon Heating & Air has been providing HVAC services for residential and commercial clients in Napa, Solano, Yolo, and Contra Costa Counties since 2018. The veteran-owned company is qualified to install, repair, and maintain everything from central heating and cooling systems to zone control systems and ductless mini splits, and its technicians are available 24/7 for the convenience of its customers.

Unlike less experienced HVAC contractors that take a “hands off” approach to keeping customers informed about their systems, Rendon Heating & Air takes the time to give its clients all the information they need. “Our customers really appreciate that we educate them about how their systems work,” affirms Mr. Rendon. “Ultimately, we want to make sure they get the best possible outcomes.”

To further differentiate itself from its competition, Rendon Heating & Air prioritizes hiring military veterans whenever possible, which Mr. Rendon says has a direct effect on the company’s standing in its community. “We stand for a higher purpose. We learned how to serve and brought that home with us, and now, we bring that mentality to our work every day.”

They were on time to our appointment. They were extremely professional and more than knowledgeable about the job they did for us. They answered all of the questions my husband had, kept the work area clean, completed the job in the time they told us, and most importantly, the price they gave us was exactly what we paid. There were no surprises.

Their professionalism, knowledge about the job and how they treated us as customers was above and beyond our expectations

Honesty is first. They won't try to sell you what you don't need yet. They sincerely care about their customers. They are the best in town by far.

I had a bad experience with another big company in town. I text David to ask for a second opinion and told him what happened, as I was upset. He didn't text me back. He called me right away to see if I was okay. He reassured me that every thing would be okay. He came the next day and all I needed was an inexpensive part, not a whole new system. He is the best, high integrity.
