Magnolia Heating, Cooling & Plumbing has served Riverside homeowners since 1951. That is more than seventy years in the same community, and it is the reason so much of our work comes from repeat customers and referrals from their friends and family.

Call us, book online, or send a service request through the form on this page. Tell us what the system is doing and roughly how long it has been happening — that helps us send the right technician with the right parts on the truck.

We run seasonal promotions on repairs, installations and maintenance throughout the year. Our current offers are listed on our Specials page, and it is worth checking before you book so you are not leaving anything on the table.

Once a year, ideally in spring before the Inland Empire heat arrives. An annual tune-up catches small problems while they are still small, keeps the system running efficiently through the hottest months, and is usually required to keep manufacturer warranties valid.

Once a year, ideally in early fall before you need it. An annual tune-up keeps the system running efficiently, catches safety issues such as cracked heat exchangers or venting problems, and helps avoid the failure that always seems to happen on the first cold night.

Start with an assessment rather than a product. We look at your filtration, ductwork, attic insulation and water supply together, because the right first move is different in every home — sometimes it is a better filter, sometimes it is sealing the ducts, and sometimes it is the water coming into the house.
