Overview
AC Repair done right
Westside Comfort Solutions is a licensed HVAC contractor serving Renton, WA that diagnoses and repairs central air conditioners and heat pumps the same day where we can.
When the AC quits in a heat wave, you want an honest diagnosis, not a sales pitch for a new system. We test the actual unit and tell you what failed and what it costs to fix.
- No-cool and weak-airflow diagnostics
- Capacitor, contactor, and compressor faults
- Refrigerant leak detection and recharge
- Frozen coil and drainage troubleshooting
- Thermostat and control repair
Why it matters
Why ac repair is worth doing right
Most no-cool calls trace back to one component, not a dead system. A failed run capacitor, a tripped float switch, a refrigerant leak, or a frozen coil will each leave you with warm air, and each has a different fix. We test the actual unit before we quote so you pay to solve the real problem.
If your system runs on R-410A, it is still fully serviceable, but the industry is moving to R-454B on new equipment and R-410A supply is tightening, which is pushing repair costs on older systems up. The two refrigerants are not interchangeable, so when a repair involves a major refrigerant or compressor failure it becomes a repair-or-replace decision. We lay out that math honestly rather than sinking money into a system near the end of its life.
Warning signs
Signs your AC needs repair
An air conditioner usually shows symptoms before it quits completely. Call when you notice:
- Warm or weak air from the vents while the system is running
- Short cycling, turning on and off without finishing a cooling cycle
- A frozen evaporator coil or ice on the refrigerant lines
- A sudden 30 to 40 percent jump in your cooling bill with no change in use
- Hard starting, buzzing, or humming at the outdoor unit
- Water pooling around the indoor unit or a clogged condensate drain
- Uneven cooling from room to room
- A burning or electrical smell from the vents (shut it off and call right away)
How it works
What to expect with ac repair
- 01
Diagnostic visit
We test the actual system, refrigerant pressures, the capacitor, the contactor, and airflow, to find the root cause instead of guessing at the symptom.
- 02
Find the root cause
We identify what failed and why, so the same fault doesn't come back a month later.
- 03
Quote before work
You get a clear price to fix it before we start, plus an honest read on whether repair or replacement is the better value.
- 04
Repair and test
We make the repair with code-correct parts, then run a full cooling cycle to confirm the system holds temperature and pressure.
Fair, upfront pricing
What affects the cost
We quote the repair after we diagnose it. What moves the price:
- The failed part (a capacitor is minor; a compressor is major)
- Whether the system needs refrigerant, and which type it uses
- How accessible the indoor and outdoor units are
- The age and condition of the rest of the system
- Whether a repair is worth it versus replacement
Every job is different, so you get a clear quote before any work starts, with no surprises. Financing is available, so the right fix doesn't have to wait. We're licensed (WESTSCS752MT) and insured, and we back our work with a 1-year workmanship guarantee.
We treat every ac repair job like it's in our own home: diagnose it right, quote it fair, and stand behind the work.

Questions
Common questions about ac repair
Can you repair my AC instead of replacing it?
Usually, yes. Most no-cool calls come down to one part, not the whole system. We diagnose the real fault first and only recommend replacement when a repair genuinely isn't worth it.
How fast can you come out for an AC repair?
We prioritize no-cool calls and reach much of the Renton area same-day. Call us and we'll confirm timing, and we answer 24/7 for emergencies.
Why is my AC running but not cooling?
Common causes are low refrigerant from a leak, a failed capacitor or compressor, a frozen coil, or a dirty condenser. We test for the actual cause instead of guessing.
What does the R-454B refrigerant change mean for my AC?
Newer systems use R-454B while older ones use R-410A, and the two are not interchangeable. Your R-410A system is still serviceable, but R-410A is getting more expensive as supply tightens. If your AC needs major refrigerant work, we'll tell you honestly whether repairing or replacing makes more sense.
Why does my AC keep freezing up?
A frozen coil usually means low airflow or low refrigerant, from a dirty filter, a failing blower, or a leak. Running a frozen system can damage the compressor, so we find the cause rather than just thawing it.
