Are you really the local Hillsboro HVAC company?

Yes — our office and warehouse are physically in Hillsboro and have been since 1974. We're not a St. Louis chain with a Hillsboro phone number.

Do you service the rural areas west of Hillsboro?

All the time. Old Lemay Ferry, Mt. Hope Road, the stretch toward De Soto — we run trucks out that way most days of the week.

Do you actually service Hillsboro?

Yes. Hillsboro is part of our regular service area. Same team, same pricing, same free estimates as homes in Hillsboro and the rest of Jefferson County.

How fast can someone get to my home?

For urgent heating or cooling issues we work hard to get a technician out the same day whenever possible. Call us and we'll tell you exactly what we can do.

Do you charge for estimates on new equipment?

No. Estimates for new HVAC system installations and replacements are always free.

Which HVAC brands do you work on?

We service all major heating and cooling brands, including Amana, Coleman, Ruud, Rheem, Lennox, Goodman, Aprilaire, and more.

What We See on Hillsboro Homes

Hillsboro homes run the gamut: 1960s ranches off Main Street with original octopus ductwork in the basement, mid-2000s subdivisions toward Lake Tishomingo with builder-grade 80% furnaces hitting end-of-life, and rural acreage west of town running on propane and split heat pumps. We've worked on every one of these configurations and stock parts for the brands the local builders actually used.

The hard well water common around Hillsboro is rough on humidifier pads and condensate lines — if you've never had your evaporator coil checked, that's the first place we look on a no-cool call here.

Ricotta Heating & Air has worked on homes across Hillsboro, Jefferson County for decades — diagnosing failed compressors, replacing aging R-410A systems, swapping smart thermostats, and sealing leaky ductwork. From quick repairs to full system replacements, we explain what's actually wrong, give you fair options, and never push equipment you don't need.

Why Hillsboro Picks Up the Phone for Ricotta First

Three generations of Hillsboro families have used us. We sponsor the youth league, we go to church here, and our techs live within a few miles of your house. When something we installed acts up, we're not hiding behind a call center — we're around the corner.
