A capacitor going weak
Capacitors quit more than any other part once heat arrives, and a spring meter reading is the only warning they give. A weak one is flagged before it strands the house.
A spring check, before the first long hot stretch
Air conditioning maintenance Denver, ready for summer
An air conditioner that has not been looked at since last summer is the one that quits in the first heat wave. Air conditioning maintenance is the standing check — coils, refrigerant charge, airflow and electrics — kept up through the year so no season is ever missed.

About this service
Air conditioning maintenance in Denver: what the check covers
Maintenance is the programme behind a single tune-up: the same thorough check of coils, charge, controls, airflow and drain, kept up on a standing schedule through the year. Visits are booked in advance, seasons are covered, and each visit leaves a written record the next one builds on.
The point of a programme is that the visits happen without anyone remembering to book them. Checks sit on a calendar matched to Denver's seasons — cooling in spring, ahead of the 90s — and the arrangement is set out on the HVAC maintenance plans page. Older central systems across Denver gain most from a record kept year over year.
- ✓Coils cleaned on every scheduled visit

What's included
What an air conditioning maintenance visit includes
Every scheduled visit covers the same ground, and the record between visits is what makes it a programme.
✓
Condenser coil cleaning
The outdoor coil is washed clean of dust and debris at each visit, so air moves through it as designed. In Denver's dusty summers a clean coil is the most useful thing a scheduled check does.
✓
Refrigerant charge check
Pressures and superheat are read against the maker's figures and noted down. A charge slipping slowly across two visits points to a leak long before the house feels it.
✓
Capacitor and controls tested
Capacitor and contactor get a meter test at every visit. Capacitors are the most common summer failure, and a weak reading shows up before it quits.
✓
Filter and blower check
Indoor coil inspected, filter checked and swapped when loaded, blower wheel looked at for the dust that chokes airflow.
✓
Condensate drain checked
Drain line checked for blockages, so condensation leaves the house instead of pooling in the pan and tripping the float switch.
✓
Full cooling cycle run
A full cooling cycle runs with the drop across the coil measured, and the numbers are written down so the next visit can be set against this one.
How it works
How an air conditioning maintenance visit works
01
Call and book the visit
Ring (720) 806-7634 and describe the system — age, last check, anything noticed. The year's visits are talked through and put on a calendar.
02
Outdoor unit first
Outside first: condenser coil cleaned, bent fins straightened, fan motor, capacitor and contactor meter-tested at the outdoor unit.
03
Indoor coil and airflow
Then the indoor side: coil looked over, filter swapped if it is loaded, and airflow taken through the system.
04
Readings and testing
Refrigerant pressures and temperatures are read and written down, the drop across the coil is measured, and a full cooling cycle runs.
05
Findings explained
Findings come back in plain words, and the readings stay behind as a written record for the following visit.
Tools & methods
Tools and methods we bring to a maintenance visit
A programme runs on readings taken the same way, visit after visit. These are the instruments.
Manifold gauge set
On the service ports at each visit, they show suction and discharge pressure, and the numbers go in the record so a slow drift shows across visits.
Multimeter and capacitor tester
A meter reads the capacitor's stored charge and looks at contactor and fan motor for wear — the component likeliest to quit in July.
Fin comb
Bent fins get combed straight again, so air can pass through the outdoor coil after a dusty spring.
Thermometers and temperature probes
Probes at return and supply show how far air cools across the indoor coil — the plainest check that the system is doing its job, visit after visit.
Static pressure gauges
Pressure readings across filter and blower show whether air moves freely or is being choked somewhere in its path.
Coil cleaner and brush
A soft brush and coil cleaner lift the season's dust from the outdoor coil without folding the fins over.
Common situations
AC checks we do across Denver
A system that has not been serviced in years
Situation
In Washington Park, a central AC has sat unopened since the day it was fitted. It still cools, yet the outdoor coil is caked in dust.
What we check
Coil cleaned, capacitor and controls tested, charge checked, full cooling cycle run with the drop measured — and the readings written down for next year.
Cooling that faded last summer
Situation
A system in Denver cooled less and less as last summer wore on, and the homeowner wants it sorted before this one.
What we check
Charge read, coil and filter checked, capacitor tested. A drifting charge or a dirty coil are the usual causes, and both show on a meter.
A new home, first summer in Denver
Situation
A family that moved to Denver recently has a central AC nobody has ever serviced, with no record of its age. They want to know its condition before summer.
What we check
The full check is worked through — coil, charge, controls, airflow, drain — findings explained in plain words, and the next visit put on the calendar.
Problems we solve
What AC maintenance catches early
Summer breakdowns usually warn in spring. A scheduled visit finds them, and the record shows whether they are worsening.
Ask a pro →↗
A dirty condenser coil
Dust on the outdoor coil stretches run times while cooling less. A spring wash gives the coil its airflow back.
A charge drifting low
Charge only ever falls because something leaks. A spring reading finds the leak while the house is still comfortable, and the record shows whether it is drifting year over year.
A blocked condensate drain
A drain clogged with algae and dust backs water into the pan and trips the float switch — or the ceiling below. Checking it belongs to every visit.
Proof you can check
Air conditioning maintenance proof you can check
Denver's cooling season is short — around 750 to 1,000 cooling degree days — but the summers run into the 90s, so a system that is checked on a schedule carries those weeks far better than one that is only looked at when it breaks.

JERRY SUNDBY — Google review
Spring, ahead of the cooling season. March through May is the usual window — Denver summers reach the 90s, so the check belongs before the system carries its heaviest load, and the year's visits sit on a calendar so none is left to memory.
Condenser coil cleaned, refrigerant charge checked, capacitor and controls tested, filter and blower looked at, drain inspected, full cooling cycle run — readings written down.
A system can cool fine while a part wears out. A capacitor going weak or a coil clogging with dust gives no warning until it fails; the visit finds those parts first, and the record shows whether they are wearing year over year.
Look at it monthly through summer and change it when light no longer passes through. A clogged filter is the most common cause of frozen coils Lion Tech Home Services sees, and it is changed on the visit when needed.
