Three fields, and we call you back.

What do you need?

If your air conditioner is blowing warm air, making unusual noises, or struggling to keep up, Bull Mountain Heating & Cooling will find out why and fix it. Most repairs cost $150 to $650, diagnosis included. The most common fixes, a failed capacitor, a refrigerant leak or a worn-out fan motor, fall in that range.

We have looked after homes in Tigard and the surrounding towns since 2003. Office hours are Monday to Friday, 8:00 a.m. to 4:30 p.m., and we offer emergency service and repair when the AC quits.

We repair and maintain home air conditioning systems in Tigard, Portland and nearby towns. Furnace repair, heat pump repair, new air conditioner and heat pump installation, ductless mini-splits and commercial HVAC each have their own page.

Signs your air conditioner needs repair

Call when your AC starts acting differently. Getting it looked at early helps you avoid a costly breakdown during the peak summer months.

  • Blowing warm air. The system runs, but the air from the vents is not cool. Low refrigerant from a leak is a common cause.
  • Unusual noises. Humming, buzzing or grinding from the outdoor unit often points to a failing capacitor or fan motor.
  • Struggling to keep up. The house never reaches the temperature on the thermostat, or the system runs far longer than it used to.

The AC repairs we make most

These are our most common AC repairs, and all three fall within the $150 to $650 range, diagnosis included.

  • Capacitor. This part gives the compressor and fan the jolt they need to start. When it fails, the outdoor unit often hums but will not start.
  • Refrigerant leak. A leak lets refrigerant escape, so the system runs without cooling the house. We find the leak and repair it.
  • Fan motor. If the fan on the outdoor unit is not spinning, the system cannot get rid of heat. A new motor gets it cooling again.

Maintenance that heads off summer breakdowns

Regular maintenance is how you keep your air conditioner from giving out on the hottest days of the year, when everyone else needs a technician too.

  • Service Club Maintenance Plan. Our maintenance plan for homeowners who want their system looked after regularly. Ask about it when you book a repair or tune-up.

  3. 03

    Repair.

What AC repair costs

What moves the number most:

  • Which part failed. A capacitor, a refrigerant leak and a fan motor each cost a different amount to fix.
  • Less common repairs. Repairs outside the most common fixes can fall outside this range.

The $150 to $650 range covers the diagnosis and the repair together for the most common fixes. Our work comes with comprehensive warranties and satisfaction guarantees.

Air Conditioning Repair & Maintenance questions we get asked

How much does AC repair cost?

Most air conditioning repairs cost $150 to $650. That includes the diagnosis and the repair. The most common fixes, a capacitor, a refrigerant leak or a fan motor, fall in that range. Less common repairs can cost more or less.

What is included in the $150 to $650 price?

Both the diagnosis and the repair. You are not paying one price to find the problem and a separate one to fix it when the repair is one of the common ones.

Do you offer emergency AC repair?

We offer emergency service and repair. Our office hours are Monday to Friday, 8:00 a.m. to 4:30 p.m.; outside them, send the form or a text and we get back to you.

Should I repair or replace my air conditioner?

It depends on your system and what failed. Many problems are a single part and fall in the $150 to $650 range. If replacement makes more sense, we also install air conditioners and heat pumps, including Rheem equipment as a Rheem Pro Partner.
