Trusted Air Conditioning Experts Serving Greater Everett, WA
Why is an AC Tune-Up Necessary?
An air conditioning system is made of many parts. Over time, those parts can wear out, while movements inside the system can cause some parts to rattle loose. These small changes might not immediately affect the function of your HVAC system, but without regular maintenance, they will eventually cause problems.
The Value of AC Maintenance

Is It Time to Replace My Air Conditioner or Can It Be Repaired?
To replace or repair, that is often the question. HVAC systems are expensive, and no one is excited about the possibility of spending thousands of dollars on a new one. The best way to answer this question is to have a trustworthy professional inspect your AC unit to determine its condition.
Our inspection check list is designed to be transparent so that homeowners can know that they are making the right decision—even if they don't understand the first thing about AC maintenance.
If your air conditioner is exhibiting any of the following problems, it's probably time to consider a replacement:
- Thermostat no longer works correctly
- Inconsistent temperature in the home
- Unpleasant odors coming from the AC unit
- Unusual sounds coming from the AC unit
- An unexplained increase in energy bills
- Signs of leakage around the air conditioner, especially coolant leaks
If the unit is approaching the end of its expected lifespan, repairs may cost more than the air conditioner is worth. If you decide that it's time for an upgrade, one of our CM Heating professionals can show you options that will fit your budget and the needs of your household.
