Frozen coils in summer
Low airflow from a clogged filter or dirty coil freezes the indoor coil. A visit catches the airflow problem before the coil ices.
Seasonal checks that keep one system heating and cooling all year
Heat Pump Maintenance Denver, Year-Round
A heat pump in Denver earns a twice-a-year habit: one check before the heating season and one before cooling. It runs all year, so it wears in both directions, and a visit in each season catches what the other would miss. Call (720) 806-7634 to book a visit.

Heat Pump Maintenance in Denver: What a Visit Covers
A heat pump maintenance visit is a full check of the system that heats and cools a home: coils cleaned, airflow measured, refrigerant pressures checked, electrical parts tested, and the defrost cycle confirmed. The point is to catch wear while it is still small.
Denver seasons are hard on heat pumps. Summer dust and cottonwood clog outdoor coils, winter ice tests the defrost cycle, and the system runs through both. A spring visit gets the cooling side ready; a fall visit gets the heating side ready. Skipping both means the first cold snap or heat wave becomes the test, and that is when breakdowns appear.
- ✓ Coils cleaned and checked
- ✓ Airflow and refrigerant tested
- ✓ Defrost cycle confirmed
- ✓ Controls and safety checks
What's included
What Our Heat Pump Maintenance Includes
A maintenance visit covers the whole system, indoors and out.
✓
Coil cleaning
The outdoor coil is cleaned and the indoor coil is checked, so airflow and heat transfer are not choked by dust, pollen, and cottonwood.
✓
Airflow and filter check
Airflow is measured and the filter is checked. A clogged filter is the most common cause of frozen coils and weak heating seen on these visits.
✓
Refrigerant check
Pressures are read and compared with the manufacturer's range. Low refrigerant points to a leak, which is flagged rather than ignored.
✓
Electrical testing
Capacitors, contactors, and motors are tested for wear. Electrical parts usually give warning signs before they fail outright.
✓
Defrost test
The defrost cycle, sensors, and outdoor fan are confirmed working, so winter icing does not catch the system out.
✓
Thermostat and controls
Thermostat settings and control wiring are checked, including auxiliary heat staging on dual-fuel systems.
How it works
Our Heat Pump Maintenance Process
01
Book the visit
Call and give the age and model of the system if known. A spring visit is booked for cooling and a fall visit for heating.
02
Inspect outdoors
The outdoor unit, coil, fan, refrigerant lines, and pad are checked, and leaves and debris are cleared from around the unit.
03
Inspect indoors
The indoor coil, filter, drain, and controls are checked, and airflow is measured at the registers.
04
Test the system
The system is run in the mode for the coming season, with temperatures, pressures, and defrost operation checked.
05
Report what we found
A note is left of what was checked, what is wearing, and what, if anything, needs attention before the season.
Tools & methods
Tools and Methods We Use
The same instruments used for repairs, applied as a 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.
Coil cleaning tools
Brushes and coil cleaner clear dust and cottonwood without bending the fins.
Inspection mirror and light
Sees the indoor coil, drain, and wiring in tight spaces.
Level and pad check
Confirms the outdoor unit sits level and drains properly, so water does not pool under it.
Typical jobs
Before and After
A system that had never been checked
Before
A heat pump had run for years without a maintenance visit. The outdoor coil was clogged, the filter was overdue, and the system strained through every hot afternoon.
After
After cleaning, a filter change, and a refrigerant check, the system ran in longer, steadier cycles and the air from the registers ran cooler.
Winter icing caught in fall
Before
A fall visit found a defrost sensor reading wrong, weeks before the first hard freeze. Left alone, the outdoor unit would have iced over in January.
After
The sensor was replaced during the visit, and the system defrosted on schedule all winter.
Weak airflow in one zone
Before
A maintenance check found a crushed duct run feeding one bedroom, which explained why that room always lagged behind the rest of the house.
After
The duct was repaired and the register balanced, and the bedroom now holds temperature with the rest of the home.
Problems we solve
Problems Heat Pump Maintenance Prevents
Most heat pump breakdowns give warning first. A maintenance visit is where those warnings are found.
Ask a pro →↗
Icing that never clears in winter
A faulty defrost sensor or control lets ice build on the outdoor unit. Testing the defrost cycle in fall finds it before January.
Capacitors and contactors wearing out
Electrical parts wear with every start. Testing them during a visit finds the weak ones before they strand the system.
Refrigerant slowly leaking away
A slow leak shows up as gradually weaker heating and cooling. Pressure checks during maintenance spot the trend early.

✓ VerifiedTwice a year is the usual rhythm: a spring visit for the cooling season and a fall visit for the heating season. A heat pump runs all year, so one visit a year leaves half the system unchecked.
Coil cleaning, airflow and filter checks, refrigerant pressure readings, electrical testing, a defrost check, and a thermostat review. A note is left of what was checked and anything that is wearing.
Spring, before the cooling season, and fall, before the heating season. Booking ahead of the season means the system is checked before it is needed most.
Regular checks catch the small problems, dirty coils, weak airflow, worn electrical parts, slow leaks, before they turn into breakdowns. That is the practical value of a visit: fewer surprises, and a system that runs steadily.
