Furnace Repair in Tacoma & Seattle
Furnace blowing cold air or refusing to start? The HVAC Rat diagnoses the real problem, quotes the repair upfront, and gets your heat back on — repair, replacement, or maintenance.
Furnace Services
Furnace Installation
Replacing a worn-out furnace with a properly sized high-efficiency model. Correct sizing, clean duct connections, and code-compliant venting on every install.
Furnace Maintenance
Annual tune-ups that clean the burners and flame sensor, check the heat exchanger, test safeties, and keep your system running efficiently all winter.
Signs Your Furnace Needs a Repair
Most furnace failures give you warning first. If you notice any of these, call before it turns into a no-heat night.
Blowing Cold Air
The blower runs but the air never warms up — often a failed igniter, flame sensor, or gas valve issue.
Short Cycling
The furnace turns on and off every few minutes. Usually a clogged filter, airflow restriction, or overheating limit switch.
Weak Airflow
Some rooms never get warm. We check the blower motor, duct restrictions, and static pressure to find the real cause.
Won't Ignite
No flame, repeated lockouts, or a blinking status light. We read the fault codes instead of guessing at parts.
Strange Noises
Banging, screeching, or rattling points to bearings, belts, or a delayed ignition that needs attention right away.
Rising Gas Bills
A furnace that's losing efficiency costs you every month. We measure performance and tell you honestly whether to repair or replace.
Repair or Replace?
A good furnace repair is almost always cheaper than a new system, and most furnaces have plenty of life left in them. We fix what can be fixed and tell you straight when it isn't worth it.
Replacement usually makes sense when the furnace is past 15–20 years old, the heat exchanger is cracked, or the repair cost is climbing toward the price of a new high-efficiency unit. In those cases we'll walk you through both options — including whether a heat pump or dual-fuel system would cost you less to run.
