Same-Day Service
Most service calls handled same-day across Spokane and Coeur d'Alene.
AC Maintenance
The cheapest AC repair is the one that never happens.
An annual tune-up catches small problems before they become emergency repairs, restores up to 5% in efficiency loss, and keeps your manufacturer warranty valid. Most importantly, it heads off the no-cooling emergency call on the hottest day of the year.
Care Club members get two annual visits, priority dispatch, and 15% off any repair work — all for less than the cost of a single emergency call.
- Efficiency restored Cleaning and calibration recover up to 5% in lost efficiency every year.
- Warranty preserved Most manufacturer warranties require documented annual maintenance.
- Failures caught early Weak capacitors, low refrigerant, and worn motors flagged before they fail.
- Safety check Electrical, refrigerant, and condensate-drain integrity tested every visit.

AC Maintenance — Frequently Asked Questions
How often should I tune up my AC?
Once a year — ideally in early spring before peak demand. If you have a heat pump that runs year-round, schedule both a spring and fall maintenance. Care Club members get the visits handled automatically.
Will a tune-up actually save me money?
Yes — and the math is straightforward. AC efficiency drops 1–3% a year without service. Over a hot summer, restoring that lost efficiency typically pays back the visit cost. Plus tune-ups catch problems before they become $1,000+ emergency repairs in 100°F weather.
Do I need a tune-up if my AC seems fine?
Yes. AC systems that ‘seem fine’ are exactly when problems are easiest (and cheapest) to fix. A weak capacitor that fails in May is a 30-minute fix; the same capacitor failing on a 100°F afternoon means an emergency call and an overheated house.
What should I do between tune-ups?
Change your filter every 1–3 months. Keep at least 2 feet of clearance around the outdoor condenser. Don’t close more than 20% of the supply registers — closed vents starve airflow and freeze the indoor coil.
What's the Care Club?
Our annual maintenance membership: two visits a year (heating + cooling), priority dispatch, no overtime fees, $0 diagnostics, and 15% off all repairs. Most members save more on the discounts than the membership costs — and you don’t have to remember to schedule anything.
*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.
