Steve's Service: Ontario, California's Best Choice for All of Its Heating & Cooling Needs

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 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.

We are available 24 hours a day to respond to routine and urgent requests.

Ductwork Repair & Replacement, Ontario, California

The HVAC technicians at Steve's 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 Service is fully licensed and insured to provide all HVAC services described above.

We called this morning about an issue with our AC. We called at 9:30am and was given a 10:00am to 1:00pm window. Oscar the technician contacted us at 10:52am to say that he would be here in 20 min. He arrived when he said he would. The problem was diagnosed quickly, and repaired, we were presented a good estimate. We had him perform a tune up service. He replaced our filters and washed down the unit. Oscar was friendly and professional. He explained all work that he was doing. I highly recommend Steve's for your AC and Heating needs.
