What’s Included in a Stan’s AC Tune-Up in Ontario

A professional AC tune-up from Stan’s Heating, Inc is more than a quick filter swap. Our technicians perform a comprehensive inspection and cleaning of your entire cooling system to catch problems early and keep your equipment running at peak efficiency through Ontario’s hot summers.

During every AC maintenance visit, we:

Inspect and replace air filters
Clean evaporator and condenser coils
Check and top off refrigerant levels
Lubricate motors and moving parts
Test thermostat calibration and controls
Inspect electrical connections and components
Clear condensate drain lines
Check airflow and duct connections

Skipping annual maintenance is one of the most common reasons AC systems fail prematurely. Dust and debris on coils reduce energy transfer efficiency, dirty filters restrict airflow and strain the motor, and small electrical issues can go unnoticed until they cause a breakdown. Scheduling a tune-up every spring in Ontario keeps your system running right and helps avoid costly emergency repairs mid-summer.

HVAC Maintenance FAQs — Ontario, OR

How often should I schedule HVAC maintenance in Ontario, OR?

We recommend scheduling AC maintenance once a year in the spring before cooling season, and furnace maintenance once a year in the fall before heating season. If you have a heat pump, one annual tune-up covering both modes is typically sufficient.

What does an HVAC tune-up include?

A Stan’s HVAC tune-up includes a full system inspection, coil cleaning, filter replacement, refrigerant check, lubrication of moving parts, thermostat calibration, electrical connection inspection, and condensate drain clearing. We check everything that affects performance, efficiency, and safety.

What’s the difference between AC maintenance and AC repair?

AC maintenance is preventative — it’s scheduled service designed to keep a working system running efficiently and catch small issues before they become failures. AC repair is corrective — it addresses a specific problem or breakdown that has already occurred. Regular maintenance is the best way to reduce the need for repairs.

Does Stan’s offer a maintenance plan or service contract in Ontario?

Yes. Stan’s Heating & Cooling offers a comprehensive maintenance agreement that includes priority scheduling, service reminders, and discounts on all our HVAC services. Contact us to learn more about enrollment for your Ontario, OR home.
