HVAC Maintenance & Tune-Up in Pine, CO

For a standard 1-inch pleated filter in a typical Colorado home: every 60-90 days. For 4-5 inch media filters: every 6-12 months. For homes with pets, allergies, or heavy dust, cut those intervals in half.

By filter type

• 1-inch fiberglass (cheapest) — replace every 30 days. We don’t recommend these.
• 1-inch pleated (most common) — replace every 60-90 days
• 2-inch media — every 4-6 months
• 4-5 inch media (Honeywell, Aprilaire) — every 6-12 months
• Washable electrostatic — clean monthly, replace every 5+ years

Colorado factors that shorten filter life

• Dry air keeps dust airborne longer (replace more often)
• Cottonwood and grass season (April-May) clogs filters fast
• Wildfire smoke (late summer) — replace immediately after any smoky stretch
• Multiple pets — cut interval by 30-50%
• Construction nearby — accelerated loading

What dirty filters actually cost you

• 5-15% lower system efficiency (higher gas/electric bills)
• Increased blower motor wear
• Iced evaporator coils in summer
• Short-cycling and high-limit trips in winter
• Reduced equipment life

If you have an annual maintenance plan with us, we replace one filter per visit (two per year) included.

Schedule a professional furnace tune-up once per year — ideally in early fall (September or October), before the first hard freeze. Front Range winters put heavy load on heating equipment, and Colorado’s dry, dusty air clogs filters and burners faster than in milder climates.

What an annual tune-up actually covers

• Inspect and clean the burners, ignition system, and flame sensor
• Inspect the heat exchanger for cracks (safety-critical)
• Combustion analysis — verify proper gas/air mixture and CO output
• Measure gas pressure at the manifold
• Test high-limit, rollout, and pressure switches
• Inspect inducer motor, venting, and condensate drain (high-efficiency units)
• Check all electrical connections and capacitor health
• Replace the standard 1-inch filter and calibrate the thermostat

Skipping annual maintenance is the leading cause of mid-winter no-heat emergency calls along the Front Range. The tune-up itself is $129 single visit or $229 for the annual plan that covers both furnace and AC. The cost of one after-hours emergency repair often exceeds five years of maintenance.

If you have pets, a finished basement, or live in an older Wheat Ridge or Edgewater home with original ductwork, you may want a second mid-season filter check — Colorado dust is no joke.

For most Colorado homes, the cheapest approach is a programmable or smart thermostat with a moderate setback (5-7°F warmer) while you’re at work — not “leaving it off” and not “leaving it running at the same temp all day.”

The myth: “It uses more energy to cool a warm house than to maintain a cool one”

This is partly true and mostly wrong. Yes, your AC works harder to bring a 90°F house back to 75°F than to maintain 75°F. But the total energy used is still less than running the AC all day. The science here is straightforward: heat transfer rate is proportional to the temperature difference between indoors and outdoors. A warmer house gains heat slower, so cumulative energy use is lower with a setback strategy.

Recommended Colorado AC strategy

• Home: 74-76°F during occupied hours
• Away: 80-82°F during work hours
• Sleeping: 72-74°F (most people sleep better slightly cooler)
• Use a smart thermostat with geofencing — it brings the house back to setpoint as you approach home, no waiting

A modern smart thermostat with proper setbacks typically saves 8-15% on summer cooling costs compared to “set it and forget it” at one temperature. Many qualifying thermostats earn a $50-$100 instant Xcel rebate.

No — never fully cover your outdoor AC unit. A top-only cover or “AC top hat” is fine and can be helpful, but a full wrap-around cover causes more problems than it solves.

Why full covers are bad

• Traps moisture inside the unit — accelerates rust on the coil and electrical components
• Creates a habitat for rodents — mice love a dark, dry, enclosed space and chew through wiring
• Damages the compressor if someone forgets and runs the AC with the cover on in early spring
• Doesn’t protect against actual threats — the inside of the unit is designed to be exposed to weather

What’s actually OK

• Top-only cover or “AC top hat” — covers just the top of the unit, blocks falling debris and ice, allows air circulation. Best of both worlds.
• Plywood weighted with a brick — same idea, free.
• Nothing at all — also fine. Modern outdoor units are weatherproof by design.

Heat pump exception

If you have a heat pump (which is also your outdoor “AC unit”), the same rules apply — never fully cover it because it’s running year-round. You may want a snow stand to lift it off the ground 12-18 inches so the defrost cycle works properly during snowy periods.

Our maintenance plans include a fall and spring visit that handles all of this. Learn more →

For most Colorado homes, “auto” is the right setting — the fan only runs when the system is actively heating or cooling. But “on” has specific use cases where it makes sense.

When “auto” wins (most homes)

• Lower electric bill — the blower draws 400-700 watts on standard PSC motors
• Less filter wear and tear
• Quieter overall
• Default recommendation for most situations

When “on” makes sense

• Allergies or air quality concerns — continuous airflow through your filter catches more particulates (only worth it with MERV 11+ filters)
• Uneven temperatures between floors — continuous fan circulation evens things out
• You have an ECM (variable-speed) blower — these use 60-100 watts at low speed, making “on” much cheaper to run
• You’re running a whole-home humidifier in winter — better distribution
