HVAC reviews in Tigard, Oregon

I highly recommend Bull Mountain Heating and Cooling to service all your HVAC needs. Eddie was early to the appointment and very professional. He troubleshoot the issues and came to a conclusion that a contactor was defective. He replaced it and it's cooling again! 😎

Matthew was excellent. Very professional, friendly, explained everything very well. Keep him around.

Brock was very responsive in addressing our problem. He diagnosed and corrected the problem within 30 minutes. It was a relief to have heat back.

We easily made our repair appointment online and Bull Mountain did their best to keep the appointment during a busy season. A quick fix and we were back in action.

Rico was amazing through the whole process of replacing our AC and installing a thermostat! Bull Mountain has earned our trust and loyalty!

Bull Mountain installed an AC unit at our house yesterday. Everything was smooth from start to finish. I know Brian and he’s one of the nice guys you’ll ever meet. They scheduled the work 3 weeks later (yesterday). The guys working here were respectful and worked quietly. I’m very happy with everything and I will refer Bull Mountain to my family and friends.

Outstanding work on a very high-end residential install.

I am a principal engineer. My interview process was extensive and I know enough about this field to differentiate the great from the good and bad contractors. I specified a lot of high-end and some special-order parts (coated coils) that most contractors are not using on residential jobs and Bull Mountain installed them with skill and pride. While I have top-of-the-line parts, I firmly believe the installation quality is 90% of the job. Without getting into too much detail: I have very high standards of work and Bull Mountain exceeded my expectations. My standards of work apply to the ducting hanging and installation techniques, duct mastic sealing techniques, gas line installation and routing, duct insulation install and tape, the lineset install, the condensate lineset, slope, and temp. management, the wiring, the venting, control systems install and positioning, register engineering and install technique, equipment support and equipment maintenance capability. I worked with Brian on the engineering of the manual-D and manual-J - his software (Elite) is as good as the best available packages that I have used (cool-calc, etc). Many contractors will run away from a job like this, Brian and team embraced it…I’m quite confident that Bull Mountain is the top HVAC contractor in the Portland/PDX area based on my extensive research and interview process. Companies like Bull Mountain deserve to be commended for the pride they take in their work and the quality of the end result. Bottom line: if you want the best, hire Bull Mountain.

It is critically important that you have your system properly engineered with manual-D/J/S and receive an AHRI cert.

Communication was horrible. Didn’t send a message that they were coming until 20 plus minutes after appointment window. Showed up 45 minutes after the appointment window when I was already gone .Took off work to be then the service wasn’t done because they were so late. I get that things run behind but would have been professional to communicate that. Never returned my calls that day or since then.

Nolan did a great job! Showed up on time (even a little early!) and extremely easy to work with. This is my 2nd time using Bull Mountain Heating and Cooling and both times were on time, efficient and very professional.

UPDATE 3/28/2025
Roberto Cervantes from Bull Mountain Heating & Cooling provided us with outstanding service and support. His work and communications with me during his service visit was high quality professional effort. He carefully share me the steps he was going to take, was respectful of our home and provided me with clear explanation of our home AC system function and his findings. Our AC system is in good order!

Roberto provided timely and professional service that reconfirms the high quality of customer service & support that is Bull Mountain hallmark for new and established customers.

For any PDX metro area homeowners seeking to update or install new heating and cooling units for their home, I recommend you plan and schedule now for any AC installation work and avoid the hot summer rush. Bull Mountain has a highly professional sales and service team to meet your home cooling or heating needs!
——————————
From the initial site visit, coordination with office for payment paperwork, a on-site follow-up review before installation and throughout the day for installation of two ductless heater/ AC units, the Bill Mountain heating and cooling team provided our family home with a high caliber of professional sales and service. The installation crew was professional and polite, and on-time! The best!!

The quality of Bull Mountain’s installation work was excellent. Respect for our home was demonstrated with the installation team’s attention to cleaning-up after the installation was complete. We sincerely appreciate Bull Mountain staff’s professional teamwork sales and installation technical support. Bull Mountain Heating and Cooling is the best!!

Bull Mountain sent Matt up right away when my furnace died. He was extremely thorough and explained everything he was be that needs to be done.

Bull Mountain has been great. They replaced furnace in Jan, great, clean, neat work. Air conditioning (separate system) stopped blowing cooled air and tech evaluating system was able to fix on the spot. Highly recommend company. I'm told company treats employees well and that definitely translates into great service for customers.

Prompt scheduling. Techs arrived right on time. Friendly and competent. No BS, just cheerfully sorted me out in minutes. Would call again, no question.

Was given a clear service window, got a text when they were on there way along with a link to track their progress.
Rico quickly assessed the issue and fixed the issue and then reset the system for better efficiency

Very pleased with my new quiet Trane furnace and the excellent service I received from Bull Mountain. I can already tell the home is heated more evenly. Everyone I dealt with was friendly, competent, professional, thorough and on time. Baltazar and his team are efficient installers and cleaned up after themselves. A positive experience! Highly recommend!

Excellent HVAC system installation. Over and beyond expectations. The crew even tried to patch up the trim around the access point although we were told that it’s not what they normally do and it’s not their area of expertise. So far so good. It’s only the first day.

Very personable young man. He explained everything he was doing and made recommendations for what he recommended. Did a great job! Billing has changed to monthly which he explained.

I had a furnace repair appointment scheduled for between 8:00 a.m. and noon. When no one arrived by 1:00 p.m., I called the company. They then canceled the appointment and offered to reschedule for a later date.

This resulted in my entire morning being wasted, plus an additional hour in the afternoon, after I had rearranged my schedule and canceled meetings to accommodate them. I received no updates or communication during the window, and no regard was shown for the inconvenience caused.

Great service once again from Bill Mtn. Patrick arrived on time, was very pleasant and professional. He gave us a candid update on our system and clearly explained his recommendations. Will continue to call on Bull Mtn. for HVAC needs.

Tech came out at late on a Sunday and tried numerous troubleshooting methods for my furnace, but was unable to fix the problem. At that point we had to escalate to installing a new furnace. Quotes came in quick and install took less than 3hrs to get done.

Great people in the office setting up the appointment, very reasonable time frame coming to my how and Rico, the tech, was a great guy. Good communication and quick service I would highly recommend Bull Mountain Heating and Cooling
