Why AC Maintenance Matters in Utah County
As a homeowner in Utah County, you know how hot our summers can get. In the summer of 2022, I remember coming home from a trip to Texas thinking I had escaped the Texas heat only to realize that it was hotter here in Utah. There is something about the dry heat we get here that makes it a killer.
And in these conditions, a well-maintained air conditioner isn’t just a luxury—it’s a necessity for comfort, safety, and energy savings. In my experience, the difference between a system that works for years and one that breaks down at the worst possible moment comes down to a little routine care.
Regular AC maintenance helps you:
- Avoid unexpected breakdowns during heatwaves
- Lower your monthly utility bills
- Extend the life of your AC unit (saving thousands in early replacements)
- Improve indoor air quality—crucial during Utah’s allergy and wildfire seasons
Whether you’re in Provo, Orem, Lehi, or anywhere else in Utah County, following an annual AC maintenance plan is one of the smartest things you can do for your home and your wallet.
The Complete AC Maintenance Checklist
In this article, I’m going to walk through a DIY modified version of our 14 step checklist that we use at Provo HVAC Repair when we perform our AC inspections giving you an inside look at how the pros do it.
While you don’t need to be a pro to perform this checklist, If while doing your maintenance you find that you want a pair of professional eyes on things or you run into some issues, and you need AC repair in Provo, Utah, call or text us today to schedule your free inspection.
1. Turn Off the Power
Safety first! Before you start any work, switch off the power to your AC at the main electrical panel and at the outdoor disconnect box. This protects you and any equipment you might use.
2. Change or Clean Your Air Filter
- Why: A clogged filter is the #1 cause of AC problems in Utah County. It restricts airflow, reduces efficiency, and can cause the system to freeze up.
- How: Find the filter slot (usually near the return duct or blower compartment). Slide out the old filter, note the size, and replace it with a new one (arrows point toward the blower). If it’s a reusable filter, rinse and let it dry completely before reinstalling.
- How often: Every 1–3 months during cooling season, or more often if you have pets or allergies.
3. Inspect the Thermostat
- DIY tip: Make sure your thermostat is set to “cool” and matches your family’s schedule. If you use batteries, replace them each spring.
- Upgrade: Consider a programmable or smart thermostat for even better comfort and savings.
4. Clean and Unblock Indoor Vents
- Walk through your home and make sure all supply and return vents are open and unblocked by furniture, rugs, or curtains. If you do have furniture in front of a vent, you want to have at least 1 foot of separate between the piece of furniture and vent for proper ventilation.
- Vacuum any visible dust or pet hair from the vent grilles for better airflow and cleaner air.
5. Check the Condensate Drain Line
- What you’ll want to do: Locate the PVC drain line coming from your indoor AC unit. This line removes condensation. Over time, algae or dirt can cause clogs.
- DIY maintenance:
- Detach the end of the line (usually near the indoor unit or outside the home).
- Use a wet/dry vacuum to suction out debris from the outdoor end.
- Pour a cup of distilled vinegar into the line to help prevent future mold and algae growth.
- Pro tip: If you notice water pooling near your indoor unit, address it right away—standing water can cause mold and water damage.
6. Clean or Replace Return Air Grilles
- Remove grilles if possible, and wipe them down with a damp cloth.
- This is a simple AC maintenance tip that keeps dust from recirculating and keeps your system running efficiently.
7. Inspect and Clean the Outdoor Condenser Unit
- Clear debris: Remove leaves, grass clippings, and any debris from around the outdoor unit. Maintain at least 2 feet of clear space for optimal airflow.
- Clean the fins: Gently spray the outside with a garden hose (never a pressure washer). Use a soft brush or fin comb to straighten bent fins if needed.
- Check the fan: Make sure the outdoor fan blades spin freely and are free of obstructions.
- In my experience: Keeping the outdoor unit clean makes a huge difference in cooling power and system life.
8. Check the Refrigerant Lines for Insulation
- Find the two copper pipes running from the outdoor unit into your home.
- The larger, insulated pipe should feel cold when the system is running. If the insulation is damaged or missing, replace it with foam AC line insulation (available at hardware stores).
9. Test System Startup
- After all cleaning, restore power and set the thermostat to cool. Let the system run for at least 15 minutes.
- Walk through your home:
- Are all rooms cooling evenly?
- Are there any strange noises or odors?
- Check the outdoor unit—is it running smoothly with no loud rattles or vibrations?
10. Listen for Unusual Sounds
- Grinding, buzzing, or banging noises can signal a failing motor or loose parts.
- If you hear anything out of the ordinary, it’s best to call Provo HVAC Repair before a small issue turns into a big one.
11. Look for Signs of Leaks
- Check around your indoor unit for any water leaks.
- Inspect refrigerant lines (look for oily residue), as this can indicate a refrigerant leak—a job for a pro.
12. Check System Airflow
- Hold your hand up to each supply vent. Is airflow strong and consistent?
- Weak airflow in just one room may mean a duct issue. Weak airflow throughout the house often means a dirty filter or larger system problem.
13. Review Your AC Maintenance Plan
- Mark your calendar for regular filter changes and a spring cleaning session.
- Save Provo HVAC Repair’s number in your phone for quick help in an emergency.
- Consider signing up for a professional AC maintenance plan—especially if you don’t want to worry about annual tune-ups.
14. Schedule Annual Professional Maintenance
- Even with the best DIY approach, there are things only a certified tech should handle: checking refrigerant levels, deep cleaning coils, and inspecting electrical components.
- Every spring, I recommend booking a professional tune-up—you’ll have peace of mind all summer.
Seasonal AC Maintenance Tips for Utah County
Utah County has unique challenges—dust storms, spring pollen, wildfire smoke, and the occasional hard water that can clog condensate lines. Here’s what you’ll want to know:
- Spring pollen and dust: Replace filters more often in April–June, and check your outdoor unit for debris after windy days.
- Wildfire season: Use high-quality filters during wildfire events and run your system on “recirculate” to avoid drawing in smoky air.
- Hard water: If you notice mineral buildup in your condensate drain or humidifier, clean these areas regularly with vinegar or a gentle descaling solution.
- After storms: Always check for debris on or around the outdoor unit after wind or rainstorms—Utah weather can change fast!
