Steve's 5 Star Service: Ontario, California's Best Choice for Reliable Heating & Air Conditioning Services

Anyone who lives or works in Ontario, knows how important a good air conditioner is, particularly during the summers. Ontario is known for temperatures that can easily exceed 100 degrees or hotter. While the winters are usually moderate by comparison, a storm system can easily make temperatures drop. This means that our Ontario customers want their A/C systems to handle heavy usage and need to know that their heaters will work on those sporadic occasions when they are needed.

Steve's 5 Star Service is Ontario's, as well as the Inland Empire's, premier HVAC contractor. We have provided affordable, expert heating and cooling services to thousands of homes and businesses since 1998. We are invested in the comfort of our customers and will go above and beyond to make sure you are satisfied. Browse the topics below or call us today to learn more about our heating and cooling sales, installation, repair and maintenance services. We are available 24 hours a day to respond to routine and urgent requests.

Our technicians are among the best in the industry. They are N.A.T.E. (North American Technician Excellence) certified and factory trained to repair and maintain any make or model in any home or business in Ontario. They have also met Carrier's strict standards for service and industry/product knowledge to qualify Steve's 5 Star Service as a Carrier Factory Authorized Dealer. As a result of our team's commitment to excellence, we have received numerous awards:

With accolades like these, it should come as no surprise that we have an A+ rating with the Better Business Bureau and the industry's highest customer return and referral rates.

Customer Reviews

Just moved into our new to us home and the AC stopped working on a 3 year old unit. Called and set up an appointment to see what went wrong. They sent John Zabatta as our service tech. He was fast at diagnosing and offering a few solutions for our issue based on different price points. He gave me his opinion on what would be best but understood price is a factor. Super friendly and respectful. Oh and for those who care, he was respectful of current times. Stepped out wearing his mask and kept his distance. If I have any future issue I will be sure to call Steves and ask for John.

I've had Steve's 5 Star Service complete a number of different Plumbing and AC related projects. Their quality has always been impeccable. Most recently Martin (one of their plumbing techs) has completed a couple of projects and his work was great. But I feel Martin could do a better job being clear on the costs of projects (labor + parts) upfront rather than after the project is completed, so there are no surprises. Also Steve's invoices do not break down the cost of labor and parts.

Ductwork Repair & Replacement, Ontario, California

The HVAC technicians at Steve's 5 Star Service are ductwork experts, who perform superior duct inspection, sealing, repair, and replacement services to the City of Ontario. Ductwork is the tubing through which your cooled or warmed air is pumped so that it can reach all of the rooms or offices in a home or business. It is often insulated and generally features vents and/or filters. Its value is often underestimated; however, a well-maintained duct system can ensure that none of your cooled or warmed air is leaking through a loose seam or hole. This means that investing in duct repairs, sealing or replacement when needed will increase the airflow throughout your home or building and help your HVAC system run more efficiently.

Call today! Steve's 5 Star Service is licensed to provide all HVAC services described above.
