Is Your AC Trying to Tell You Something?

Don't wait until it quits completely. These are signs your system needs attention.

Warm or uneven airflow throughout the home

System running constantly but not reaching the set temperature

Unusual sounds — grinding, banging, or high-pitched squealing

Ice forming on the unit or refrigerant lines

Water pooling around the indoor air handler

Noticeably higher electric bills with no change in usage

System is 12+ years old and requiring frequent repairs

Not Sure Whether to Repair or Replace?

We'll always give you the honest answer — even if it's not the most profitable one for us.

Repair makes sense when…

  • System is under 10 years old
  • Repair cost is less than 50% of replacement cost
  • No history of recurring issues
  • Efficiency is still reasonable

Replacement makes sense when…

  • System is 12–15+ years old
  • Repair costs keep adding up
  • Efficiency rating is low — you're paying for it monthly
  • R-22 refrigerant system (being phased out, expensive to service)

Had NW Summit change out my furnace and AC. Will definitely recommend them to any of my friends or family needing any HVAC work. Mario came out and was able to give a quote that same day. Answered any questions I had and overall had a great experience. Well done.

Mario went above and beyond to help us out when our furnace went out. He came on a Sunday to diagnose the problem and was able to get the furnace running. Then came back to replace a part. I heartily recommend NW Summit Heating and Cooling for all your heating and cooling needs. Very reasonably priced.

I reached out to this company for an AC repair. They were able to schedule me in right away. Same day that I reached out they were able to come out and check it out and do the repair the same day.

I had a great experience with NW Summit! The team was professional, punctual, and clearly knowledgeable. They quickly diagnosed the issue with my AC and had it up and running in no time. They explained everything in a way I could understand and didn't try to upsell anything unnecessary. Honest pricing, great service, and friendly technicians — highly recommend to anyone needing HVAC work done right!
