Breakdowns in the worst week
Systems fail when they work hardest, the first cold snap, the first heat wave. A visit before the season finds the wear that would have failed then.
Seasonal visits that catch wear before it becomes a breakdown
HVAC Maintenance Denver: Preventive Care
The preventive approach to HVAC maintenance in Denver is a visit before the season, not a repair after the failure. Furnaces are checked in fall, AC in spring, and heat pumps twice a year, because a heat pump works both seasons. Call (720) 806-7634 to book a visit.

Preventive HVAC Maintenance in Denver: What a Visit Covers
Preventive maintenance is a scheduled check of heating and cooling equipment before the season it will work hardest: cleaning, testing, and measuring, so wear is found while it is still small and the system is ready when the weather turns.
Denver seasons are the test. A furnace that has not been checked faces its first cold snap untested; an AC that has not been cleaned faces July with clogged coils. A maintenance visit is where the worn capacitor, the dirty coil, the slow leak, and the clogged filter are found, in spring or fall, when there is time to fix them, instead of in January or July, when there is not.
- ✓ Furnace checked in fall
- ✓ AC checked in spring
- ✓ Heat pumps checked twice a year
- ✓ Wear found while it is small
What's included
What Our Preventive Maintenance Includes
A preventive visit covers the system that is about to work hardest, season by season.
✓
Furnace check
The furnace is cleaned and tested before winter: burners, ignition, safety controls, airflow, and the filter. The system is tested in heating mode before the first cold snap.
✓
AC check
Coils are cleaned, refrigerant charge is checked, and capacitors and airflow are tested before summer, so the system is ready for the first heat wave.
✓
Heat pump check
The heat pump is checked in spring and again in fall, coils, airflow, refrigerant, and the defrost cycle, because it works all year.
✓
Boiler check
The boiler is cleaned and tested before winter: controls, pressure, and the parts that wear first, with radiators bled where needed.
✓
Filter and airflow
The filter is checked and airflow is measured, because a clogged filter is the most common cause of the breakdowns seen on these visits.
✓
Written note
A note is left of what was checked, what is wearing, and what, if anything, needs attention before the season.
How it works
Our Preventive Maintenance Process
01
Book the season
Call and say what systems the home has. Furnace and boiler visits are booked for fall, AC visits for spring, and heat pump visits for both.
02
Inspect the system
The equipment, coils, filters, and duct connections are looked over, and anything worn or dirty is noted.
03
Clean and test
What needs cleaning is cleaned and the system is tested in the mode for the coming season, heating in fall, cooling in spring.
04
Measure and record
Airflow, temperatures, and pressures are measured and recorded so the next visit can compare against them.
05
Report what we found
A note is left of what was checked and anything that needs attention, so the decision is made with the facts in front of the homeowner.
Tools & methods
Tools and Methods We Use
The same instruments used for repairs, applied as a preventive check-up before anything breaks.
Manifold gauge set
Reads refrigerant pressures against the manufacturer's range to spot a slow leak early.
Multimeter
Tests capacitors, contactors, and motors for wear before they fail.
Thermometer and airflow checks
Supply and return readings show whether the system is moving heat properly.
Combustion check
Tests burner operation and venting on gas furnace and boiler visits.
Coil cleaning tools
Brushes and coil cleaner clear dust and cottonwood without bending the fins.
Inspection mirror and light
Sees coils, drains, and wiring in tight spaces.
Typical jobs
Before and After
A furnace never checked
Before
A furnace had run for years without a visit. The filter was overdue, the burners were dirty, and the system strained through every cold week.
After
After cleaning, a filter change, and a safety check, the furnace ran steadily and the house held temperature through the winter.
An AC that failed every July
Before
An AC broke down in July two years running, each time on the hottest weekend. The coil was clogged and a capacitor was weak.
After
A spring visit now catches the coil and the capacitor before summer, and the July breakdowns have stopped.
A heat pump checked twice a year
Before
A heat pump that works all year had only ever been checked when it broke. Each repair came in the worst week of the season.
After
Spring and fall visits now catch wear in both directions, and the system has run through two full years without a breakdown call.
Problems we solve
Problems Preventive Maintenance Prevents
Most breakdowns give warning first. A preventive maintenance visit is where those warnings are found.
Ask a pro →↗
Dirty coils and clogged filters
Dust and cottonwood clog coils and filters every Denver summer. Cleaning them in spring restores airflow before the heat arrives.
Worn electrical parts
Capacitors and contactors wear with every start. Testing them during a visit finds the weak ones before they strand the system.
Slow refrigerant leaks
A slow leak shows up as gradually weaker heating and cooling. Pressure checks during maintenance spot the trend early.

✓ VerifiedFurnaces and boilers in fall, before the heating season; AC in spring, before the cooling season; heat pumps in both spring and fall, because they work all year.
Cleaning, testing, and measuring: coils, filters, airflow, refrigerant pressures, electrical parts, and safety controls. A note is left of what was checked and anything that is wearing.
Older systems benefit most, since they have the most wear to find. A visit shows honestly what is wearing and whether repair or replacement makes more sense, before the system fails in the worst week.
Maintenance is a scheduled check before the season; a repair fixes something that has already failed. Maintenance finds the wear that would become the repair.
