What’s included in a tune-up
We clean coils, check refrigerant and electrical components, inspect safety controls, and verify the system is performing the way it should — then share simple recommendations to protect your investment.
Why coil cleaning matters in NC humidity
Dirty outdoor coils choke airflow and efficiency. Our foaming coil cleaning restores heat transfer so your AC or heat pump doesn’t have to work overtime in humid Johnston County summers.

Frequently Asked Questions
How often should I get HVAC maintenance?
Most homes benefit from at least one thorough tune-up per year — ideally before peak cooling or heating season. Twice a year is even better for older systems.
Does maintenance really prevent breakdowns?
It can’t prevent every failure, but cleaning coils, checking electrical parts, and catching wear early dramatically reduces emergency calls.
Do you clean outdoor AC coils?
Yes. Foaming coil cleaning is one of our most requested maintenance services for Johnston County systems.
Which towns do you serve for maintenance?
Smithfield, Clayton, Garner, Fuquay-Varina, Dunn, Knightdale, Wendell, and surrounding Johnston, Harnett & eastern Wake communities.
