Furnace Repair in Murrieta

Murrieta sits in the inland valley where temperatures can swing from the low 30s on a January night to triple digits in summer, and when a furnace quits during one of those cold snaps, the discomfort sets in fast. The region’s Mediterranean-influenced climate means most homes run their heating systems hard for only a few months a year, which is exactly when deferred maintenance catches up with you. RT Olson Plumbing, Heating and Air Conditioning responds 24/7, dispatching from Corona to get your heat back on before another cold night sets in.

Why Murrieta Homes See Furnace Problems When They Do

Because Murrieta’s winters are relatively mild, most furnaces sit dormant from late spring through early fall. When a unit fires up for the first time in October or November, months of inactivity can reveal problems that weren’t obvious in spring: cracked heat exchangers that expanded and contracted through summer heat, dirty flame sensors coated with dust from a dry Inland Southern California summer, or ignitors that have simply reached the end of their service life. Homes built during Murrieta’s rapid growth period in the late 1990s and 2000s are now old enough that original HVAC equipment is approaching or past its expected lifespan, 15 to 20 years for most forced-air furnaces. That combination of age and seasonal dormancy is a reliable recipe for a no-heat call.

Local air quality also plays a role. The Santa Ana winds that push through the Temecula Valley corridor carry fine particulate matter that loads air filters faster than homeowners expect. A clogged filter starves a furnace of airflow, triggering high-limit shutoffs and leaving the blower running while the burners stay off, which is exactly what a furnace blowing cold air feels like from the register.

Our Furnace Repair Process in Murrieta

When we arrive, the diagnostic starts before a single panel comes off. We note what the thermostat is doing, whether the blower is running, and what error codes, if any, the control board is displaying. Modern furnaces log fault sequences, and reading that history tells us whether the unit is tripping on high temperature, a pressure switch, or a failed ignition sequence.

From there, the process moves through a logical sequence:

• Combustion and airflow check, filter condition, return air clearances, and static pressure across the system.
• Ignition system inspection, hot surface ignitor resistance, flame sensor microamp reading, and gas valve operation.
• Heat exchanger visual inspection, cracks or corrosion here affect both efficiency and safety; we note findings and walk you through what we see.
• Flue and venting check, particularly relevant in Murrieta homes where attic-mounted furnaces vent through the roofline; bird nesting and debris blockage are more common than most homeowners realize.
• Repair and test cycle, once the repair is made, we run the unit through a full heat cycle and verify supply air temperature at the register before we leave.

Reaching Murrieta from Corona

RT Olson’s home base in Corona puts us on the I-15 corridor, the same freeway that connects Corona directly to Murrieta. Because we operate 24/7, we can dispatch outside of peak traffic windows when that drive moves quickly. For calls that come in during daytime hours, our team coordinates routing to minimize delay. Whether you’re in a newer tract development on Murrieta’s western edge or a home closer to the city’s older core near Old Town, we’re on the same freeway spine that makes this part of Southwest Riverside County accessible.

Local Note

Murrieta’s building boom of the late 1990s through mid-2000s produced a large number of two-story homes with attic-mounted or closet-mounted furnaces, configurations that are common in Southern California but that require a different service approach than basement installs. Attic units in particular accumulate heat during summer and can develop refrigerant line and flue connection issues from thermal cycling that ground-level units don’t experience at the same rate. If your furnace is mounted in the attic and hasn’t been serviced since it was installed, that’s the first place we look when a no-heat call comes in.
