HVAC Maintenance & Tune-Ups for Colorado Homes
Annual maintenance is the single best investment you can make in your HVAC equipment. Right Way Mechanical’s tune-ups catch the small issues — a weak capacitor, a marginal flame sensor, a clogged condensate drain — before they leave you without heat in January or without AC in July.
Most no-heat emergency calls Shane runs in the dead of winter are systems that hadn’t been serviced in 3+ years. Don’t be that house.
What’s Included in Every Tune-Up
This isn’t a 15-minute filter check. A proper maintenance visit takes 60-90 minutes and goes through every safety, performance, and reliability check the equipment manufacturer specifies — plus a few more we’ve learned matter at Colorado altitude.
Furnace Tune-Up (Fall)
- Inspect and clean burners, ignition system, and flame sensor
- Inspect heat exchanger for cracks (safety-critical)
- Combustion analysis — verify proper gas/air mixture
- Measure gas pressure at the manifold
- Test safety controls — high limit, rollout, pressure switch
- Inspect inducer motor and venting
- Check all electrical connections and capacitor health
- Test blower motor amperage and RPM
- Replace standard 1″ filter (or check thicker filter)
- Calibrate thermostat
- Verify CO levels in flue gas
- Full written report on system condition
AC Tune-Up (Spring)
- Clean outdoor condenser coil (huge efficiency impact)
- Clean indoor evaporator coil
- Check refrigerant charge — measure superheat/subcool
- Test capacitor and contactor
- Inspect refrigerant lines and connections
- Check condensate drain — flush if needed
- Test all electrical components
- Lubricate bearings (older units)
- Verify proper temperature drop (15-22°F across coil)
- Test thermostat calibration
- Inspect outdoor disconnect and wiring
- Full written report on system condition

The Annual Maintenance ROI
The Math Most People Don’t Do
A typical Colorado furnace + AC system costs $9,000-$15,000 to replace. An annual tune-up costs $129-$229. The maintenance plan extends equipment life 3-5 years on average. That’s $2,500-$5,000 in deferred replacement cost for $1,145-$1,145 spent over 5 years. Plus you avoid the $400+ after-hours emergency call when it dies on a Saturday in January.
When to Schedule
Furnace Tune-Up
Best window: September – October
Schedule before the first hard freeze. Heating equipment that sits idle all summer often has issues that only show up under load — better to catch them in October than discover them at 2 AM in January.
AC Tune-Up
Best window: April – May
Before the first 90°F day. AC condensers accumulate dust, cottonwood, and Colorado wind debris all winter. Cleaning the coil before peak season recovers 10-15% of cooling efficiency.

Frequently Asked Questions
How often should I change my furnace filter?
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
How to Tell If a Filter Needs Changing
Pull the filter out. Hold it up to a bright light or window. If you cannot see light through it, replace immediately. If you can see light but the surface is gray, schedule a replacement in the next 1-2 weeks. If it looks clean, you have time.
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.
How often should I service my furnace in Colorado?
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.
Best Booking Window
Mid-September through mid-October. Earlier is fine. Wait until November and you’re competing with everyone else for service slots after the first cold snap.
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.
Is it cheaper to leave the AC on all day or turn it off?
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
Colorado Diurnal Swing Bonus
Colorado’s dry air means temperatures drop significantly overnight even after hot afternoons. Open windows when the outdoor temp drops below your indoor temp (usually by 9-10 PM) and let nature do the cooling. Close the house up in the morning before it heats back up. This trick alone can cut summer AC use 20-30%.
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.
Should I cover my outdoor AC condenser in winter?
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.
The Real Winter Maintenance Tasks
What actually matters in Colorado winters is keeping the unit clear of heavy snow accumulation (especially if it’s blocking the top), making sure no tree branches fall on it, and clearing pine needles or leaves from the coil fins. A spring tune-up addresses anything that did get inside over winter.
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.
