Seasonal HVAC Maintenance Tips To Keep Your System Running Smoothly

Keeping your heating and cooling equipment in peak condition is not optional on the Wasatch Front—it is the only way to stay comfortable through our volatile spring thaws, scorching summers, crisp autumns, and frigid winters. At Salt City Plumbing, Heating & Air, we treat maintenance as a year-round strategy that prevents breakdowns, maximizes efficiency, and preserves the life of your equipment. Use the season-by-season guide below to tackle basic upkeep and know when our certified technicians should step in.

Why Seasonal Maintenance Matters

• Efficiency first. Clean coils, calibrated thermostats, and proper refrigerant levels can slash energy use by ten to fifteen percent or more.
• Fewer emergencies. Small issues caught early—loose electrical connections, worn belts, minor refrigerant leaks—never get the chance to become 2 a.m. no-heat calls.
• Longer service life. A well-maintained system routinely lasts three to five years longer than a neglected one.
• Health & safety. Clear condensate drains reduce mold risk; verified carbon-monoxide alarms safeguard your family.

Spring: Air-Conditioning Tune-Up Checklist

1. Replace the air filter (1-in. fiberglass every 30 days; 2-in. pleated every 60 – 90 days).
2. Rinse the outdoor condenser coil with a low-pressure hose—straighten flattened fins with a fin comb.
3. Tighten electrical terminals and inspect the contactor for pitting.
4. Lubricate blower-motor bearings if fittings are present; many newer motors are permanently sealed.
5. Test capacitor microfarads against nameplate values; replace anything more than 6 percent off-spec.
6. Verify thermostat accuracy with a calibrated digital thermometer; recalibrate or upgrade to a smart stat if the deviation exceeds 2 °F.

Call us if you measure low refrigerant superheat/subcool or see oil staining on line-set insulation—leak indicators requiring an EPA-licensed technician.

Summer: Keep Cooling Costs in Check

• Shade the condenser. A pergola or tall shrub placed 2 – 3 ft away can lower condensing temperature by up to 5 °F without restricting airflow.
• Program temperature setbacks. Set 78 °F while home, 85 °F away. Each degree above 72 °F saves roughly 3 percent in cooling costs.
• Clear debris weekly. Grass clippings and cottonwood fluff clog coil fins fast—five minutes with a soft-bristle brush prevents a mid-July compressor burnout.
• Inspect duct insulation in attics or crawlspaces; repair gaps with foil-backed mastic tape, not cloth duct tape.

Fall: Furnaces Ready for the First Freeze

1. Change the filter before the first heating cycle.
2. Vacuum burner compartments and clean flame sensors with 220-grit emery cloth.
3. Check heat-exchanger integrity—look for rust flakes or hairline cracks with a bright flashlight and mirror.
4. Test igniter resistance (typical hot-surface igniters read 40 – 90 Ω).
5. Confirm gas pressure (usually 3.5 in. wc for natural gas) and adjust the regulator if necessary.

Call us immediately if you smell gas, see a wavering yellow flame, or observe elevated CO readings above 9 ppm on a consumer monitor.

Winter: Heating System Care & Safety

• Replace the filter every 30 days—dry winter air carries extra dust.
• Inspect vent piping for ice blockage and ensure the slope rises ¼ in. per foot away from the furnace.
• Verify carbon-monoxide and smoke detectors—press the test button monthly, replace batteries every six months, and swap units after seven to ten years.
• Listen for rumbling or booming on startup. Our techs should correct delayed ignition signals, burner, or gas-valve issues before heat-exchanger damage occurs.

Keep exhaust and intake clear. Shovel snow away from sidewall terminations; a blocked pipe can trip pressure switches and shut down the furnace.

Year-Round Best Practices

Task	DIY Frequency	Professional Frequency
Air-filter replacement	1 – 3 months	—
Thermostat calibration	Check each season	At annual tune-up
Refrigerant level & leak check	—	Every spring
Duct-seal inspection	Visual each season	Pressure test every 2 years
Full system tune-up	—	Twice a year (spring & fall)

DIY vs. Professional Service—Know the Line

• DIY-Friendly: Filter swaps, outdoor-unit rinsing, thermostat programming, basic visual inspections.
• Professional-Only: Refrigerant charging, electrical megger testing, combustion analysis, duct blast or blower-door testing, gas-valve calibration, and any repair that interacts with sealed refrigerant circuits or gas trains.

When performance drops, strange noises start, or any safety readings fall out of spec, call Salt City Plumbing, Heating & Air. Our NATE-certified technicians bring precision instruments, factory-authorized parts, and a truck stocked for 90 percent first-visit repair completion.

The Bottom Line

Consistent, season-specific maintenance is the surest path to year-round comfort, lower energy bills, and longer equipment life. Handle the quick-hit tasks on this checklist yourself, and rely on our team for the technical work that demands professional expertise. Together, we will keep your HVAC system running smoothly—no matter what Utah’s weather decides to throw our way.
