Your Trusted NATE-Certified HVAC Experts Serving Modesto and Beyond

 For over 25 years, Dycus Heating & Air Conditioning has been the go-to heating and cooling company for homeowners across the Central Valley, not because we’re the biggest name in the region, but because we show up, do the work right, and stand behind it. Every technician on our team is NATE-certified. Every diagnosis is honest.

Areas We Serve

Stanislaus County

📍 Modesto

HVAC | Cooling  | Heating | Indoor Air Quality 

Modesto is where Dycus Heating & Air Conditioning started, and it’s where we’ve done more installs, repairs, and tune-ups than anywhere else in the Valley. When summer temperatures push past 105°F, and your AC starts losing ground, you need a skilled HVAC team that picks up the phone and shows up the same day.

📍 Ceres

HVAC | Cooling  | Heating | Indoor Air Quality 

HVAC | Cooling  | Heating | Indoor Air Quality 

Ceres sits right next to Modesto, and the heat here is just as unforgiving in July. A lot of Ceres homes run older cooling systems that haven’t been properly serviced in years; they work until they don’t. Our reliable HVAC technicians handle everything from emergency AC repairs to full system replacements, without padding the quote.

📍 Hughson

HVAC | Cooling  | Heating | Indoor Air Quality 

HVAC | Cooling  | Heating | Indoor Air Quality 

Hughson is a small community with real Central Valley summers, the kind where a failing air conditioner is not a minor inconvenience. We serve Hughson for AC repair, heating service, and indoor air quality upgrades. If you haven’t had your HVAC system checked in a few seasons, there’s a good chance it’s working harder than it should.

📍 Denair

HVAC | Cooling  | Heating | Indoor Air Quality 

HVAC | Cooling  | Heating | Indoor Air Quality 

Denair’s rural character means a lot of homes here have older systems, less common configurations, and sometimes no one nearby who knows how to work on them. Our NATE-certified technicians serve Denair the same way they serve Modesto every day. Whether it’s a heating repair in January fog or an AC installation ahead of summer, we make the trip.

📍 Keyes

HVAC | Cooling  | Heating | Indoor Air Quality 

HVAC | Cooling  | Heating | Indoor Air Quality 

Keyes is a tight-knit community that the bigger HVAC companies tend to skip over. We don’t. Our dedicated service covers Keyes fully, including heating repairs, cooling installations, indoor air quality work, and system maintenance for homes running the same equipment for a decade or more. If your system is cycling too often, that’s worth a call.

📍 Turlock

HVAC | Cooling  | Heating | Indoor Air Quality 

HVAC | Cooling  | Heating | Indoor Air Quality 

Turlock is the second-largest city in Stanislaus County and one of the fastest-growing communities in the Valley. Newer homes here often come with systems sized for the build cost, not for the homeowner’s actual comfort. Our expert Turlock HVAC team assesses what your home actually needs and handles everything from cooling upgrades to furnace replacements.

📍 Riverbank

HVAC | Cooling  | Heating | Indoor Air Quality 

HVAC | Cooling  | Heating | Indoor Air Quality

Denair’s rural character means a lot of homes here have older systems, less common configurations, and sometimes no one nearby who knows how to work on them. Our NATE-certified technicians serve Denair the same way they serve Modesto every day. Whether it’s a heating repair in January fog or an AC installation ahead of summer, we make the trip.

📍 Salida

HVAC | Cooling  | Heating | Indoor Air Quality 

HVAC | Cooling  | Heating | Indoor Air Quality 

Salida has seen significant residential growth over the past decade, and many newer homes are now reaching the age where HVAC systems need their first serious attention. Our skilled contractors in Salida handle preventive maintenance, system diagnostics, cooling repairs, and heating tune-ups that keep a newer system running efficiently before it fails in August.

San Joaquin County

📍 Manteca

HVAC | Cooling | Heating | Indoor Air Quality 

Manteca is our second major market, and we treat it that way. The city has grown enormously over the past 15 years, bringing a wide range of housing stock from older downtown homes to large new subdivisions. Our skilled technicians in Manteca handle AC repairs, full system replacements, furnace service, and indoor air quality upgrades across all of it.

📍 Ripon

HVAC | Cooling | Heating | Indoor Air Quality 

HVAC | Cooling | Heating | Indoor Air Quality 

Ripon has the feel of a community where people know their neighbors and notice quickly when a recommendation is genuine. We serve Ripon for heating and cooling repairs, system installations, and HVAC maintenance with the same honest approach this company was built on. No upselling, no manufactured urgency. We tell you what it costs before we start.

📍 Lathrop

HVAC | Cooling | Heating | Indoor Air Quality 

HVAC | Cooling | Heating | Indoor Air Quality 

Lathrop is a planned community with a lot of newer homes, and newer homes have a specific HVAC challenge: systems installed during construction that haven’t been properly tuned since. Our skilled team in Lathrop handles commissioning checks, preventive maintenance before peak seasons, and full cooling and heating service when something starts going wrong. Better to catch it early.

📍 French Camp

HVAC | Cooling  | Heating | Indoor Air Quality 

HVAC | Cooling  | Heating | Indoor Air Quality 

French Camp is one of the older unincorporated communities in the county, with a mix of long-standing residential properties that have seen many HVAC systems come and go. We serve French Camp for heating repairs, AC service, and indoor air quality work. If you’re unsure what condition your system is actually in, a diagnostic visit will tell you clearly.

📍 Stockton

HVAC | Cooling | Heating | Indoor Air Quality 

HVAC | Cooling | Heating | Indoor Air Quality 
Stockton is the largest city in our service area, with housing ranging from older urban properties to newer suburban developments. Our expert technicians serve all of it: AC repair, heating installation, indoor air quality systems, and emergency HVAC calls. San Joaquin Valley summers don’t take it easy on Stockton, and a system barely working in June will fail by August.

📍 Tracy

HVAC | Cooling | Heating | Indoor Air Quality 

HVAC | Cooling | Heating | Indoor Air Quality 

Tracy has become a primary destination for Bay Area residents relocating to the Central Valley, meaning homeowners here expect a certain standard of service. Our trusted HVAC team in Tracy is NATE-certified, punctual, and communicates clearly from the diagnostic to the completed job. Heating, cooling, and indoor air quality service done the right way, every time.

📍 Escalon

HVAC | Cooling | Heating | Indoor Air Quality 

Escalon is an agricultural community where people want things fixed right the first time and don’t want to be talked into something they don’t need. That’s exactly how Dycus Heating & Air Conditioning operates. We serve Escalon for AC repairs, furnace service, heating installations, and indoor air quality work, priced honestly. Call us, and we’ll tell you exactly where things stand.
