Are you familiar with the older homes on Mississippi Avenue?

Very. We've retrofitted central air into half the brick two-stories on that side of town. Tight crawlspaces, finished plaster ceilings — we know how to route ductwork without tearing your house apart.

Yes. Festus 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?

Festus Homes Run a Real Range

Festus has solid 1950s brick ranches with original gravity-fed ductwork, 1990s subdivisions on the west side that all got the same builder-grade Goodman furnaces (most are now due), and rural acreage running propane split systems. The river-valley humidity here also chews up evaporator coils faster than further west — annual coil cleaning is genuinely worth it in Festus.

Ricotta Heating & Air has worked on homes across Festus, 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 Festus Homeowners Trust Ricotta for Furnace Repair

When your furnace quits during a Missouri cold snap, you want a local technician who picks up the phone, shows up on time, and gives you a clear answer — not an upsell. That's been our promise to Festus homeowners for over 50 years.
