Our Heating & Furnace team doesn’t treat Rohnert Park like an afterthought.

Our Heating & Furnace Services in Rohnert Park
Furnace Repair
A dead furnace in Rohnert Park isn’t just uncomfortable, it’s genuinely dangerous when temperatures drop. We repair ignitor failures, faulty gas valves, blower motor issues, and control board problems across every major brand. Because so many local systems are original or second-generation equipment, we carry parts for older Lennox, Goodman, and Rheem models that big-box retailers stopped stocking years ago. Most repairs are completed in a single visit.
Furnace Replacement
Rohnert Park’s unique housing situation demands a replacement strategy most contractors don’t understand. Homes built in the same section often share identical ductwork chases sized for 1970s low-static furnaces. Slapping a modern high-efficiency unit into that infrastructure without calculating static pressure and airflow creates hot and cold spots, premature failure, and wasted energy. Daniel evaluates the full system, not just the box in your garage or closet. A typical replacement in Rohnert Park runs $4,130–$8,850 depending on duct remediation needs and efficiency tier.
Furnace Tune-Up
Annual maintenance in Rohnert Park pays for itself. Our tune-ups run $95–$235 and include combustion analysis, heat exchanger inspection, gas pressure verification, and blower cleaning. For homes with original ductwork, we also check static pressure and airflow balance. Given the age of local housing stock, we catch cracked heat exchangers and deteriorating flue connections before they become carbon monoxide hazards. We also handle Air Quality & Ventilation in Rohnert Park for homeowners concerned about indoor air safety.
Heat Exchanger Inspection & Replacement
This is the repair that separates competent technicians from dangerous ones. A cracked heat exchanger can leak carbon monoxide into your living space, and in Rohnert Park’s 40-to-60-year-old furnaces, we find them regularly. Daniel uses both visual inspection and combustion analysis to verify integrity. If replacement is needed, we provide documentation for insurance or warranty claims and never pressure a full system replacement when a heat exchanger repair is viable.

Common Heating & Furnace Problems We See in Rohnert Park Homes
- Cracked heat exchangers in original-section furnaces. The early 1960s core near Roberts Lake still contains oil-to-gas-converted units and first-generation gas furnaces with heat exchangers that have cycled through 50+ winters of thermal stress. We inspect these with combustion analyzers every time.
- Undersized ductwork causing high static pressure. Rohnert Park’s tract homes were built with duct chases designed for low-static furnaces running at single speeds. Modern variable-speed equipment often struggles against that resistance, leading to premature blower failure and uneven heating.
- Failed ignitors in 1980s-era systems. The south and east sections built in the final development phase commonly have furnaces now hitting their design end-of-life. Hot surface ignitors and flame sensors fail predictably after three decades of cycling.
- Gas valve and regulator issues from original conversions. Homes that converted from oil heating in the 1960s and 1970s sometimes retain older gas train components that don’t play well with modern control boards, causing intermittent ignition failures that frustrate homeowners and confuse less experienced technicians.

Repair costs are comparable across southern Sonoma County, but Rohnert Park’s older housing stock can push some jobs toward the higher end of our $175–$825 range. Original-section homes may need additional safety upgrades to flue venting or gas piping that newer construction doesn’t require. We quote everything upfront before starting work.
