When to Call

Cooling problems we solve every day

Catching small problems before they become emergencies is the easiest money you can save on cooling costs.

  • Warm air from the vents

    Could be low refrigerant, a frozen coil, or a failing compressor — all worth a same-day check.

  • Weak or uneven airflow

    Some rooms cool, others don't — usually airflow, ductwork, or a failing blower motor.

  • Loud or unusual noises

    Banging, grinding, or hissing usually points to a loose part, motor wear, or a refrigerant leak.

  • Water around the unit

    A clogged condensate drain can cause indoor leaks and water damage to ceilings and floors.

  • Short cycling

    System turning on and off repeatedly wastes energy and shortens equipment life.

  • System over 10 years old

    Older systems lose efficiency every year — replacement often pays back faster than another big repair.

Ricky Saldana the technician that came out was fantastic. He was so knowledgeable about my plumbing issues and his recommendations were spot on. He was on time and very pleasant to work with. I would highly recommend him for any plumbing work that needs to be done. Thanks Ricky for all of your input.

Cooling — Frequently Asked Questions

How fast can someone get to my house when the AC is out?

For most service requests in Spokane, Coeur d’Alene, and surrounding areas, we offer same-day appointments. Emergency calls (no cooling, water leaking, electrical concerns) get priority dispatch 24/7 — including weekends and holidays — at no after-hours surcharge.

Do you service my brand?

Yes. We repair every major residential brand including Carrier, Trane, Lennox, Rheem, Goodman, York, American Standard, Bryant, Amana, Daikin, and Mitsubishi — plus most heat pumps and ductless mini-splits installed in the Inland Northwest.

Should I repair or replace?

If your system is more than 10–12 years old and you’re facing a major repair, replacement often pays back faster in efficiency savings and reliability. We’ll give you the honest tradeoffs — including a free second opinion if another company has quoted you a replacement.

Are repairs and installs warrantied?

Every repair includes a 1-year Mainstream labor warranty plus the full manufacturer parts warranty. New installations get a 10-year parts warranty and a 2-year labor warranty when you join our Care Club.

Do you offer financing?

Yes. We offer flexible financing — including no-interest plans for qualified customers — so a cooling emergency or planned upgrade doesn’t have to wait. Our team walks you through the options during the visit.

*Offers cannot be combined with other promotions or applied to dispatch fees. No cash value. Must present offer at time of service. Call for details.
