Coil cleaning, inside and out
The outdoor coil collects dust, pollen and tree debris; the indoor coil collects whatever the filter missed. Clean coils restore heat transfer and cut the runtime needed to hold setpoint on a hot afternoon.
The spring tune-up, done before the cooling season
AC Tune-Up in Fort Collins, CO
This is the canonical how often to schedule AC tune-ups page for DNA Refrigeration Heating & Cooling. One page, one seasonal visit, no duplicates: a how to clean and maintain your AC before summer AC tune-up is an inspection, cleaning and testing visit that finds the small faults — a weakening capacitor, a dirty coil, a low charge, a clogged drain — while they are still small. Fort Collins gives you a clear window for it: March to April, after the heating season and before the first 90-degree day. Book it then, and the system that has sat idle all winter gets checked before it is asked to run flat out all summer. Call (970) 932-2324 any time.
About this service
What an AC tune-up in Fort Collins really involves
A tune-up is a 21-point style inspection and cleaning: coils cleaned, refrigerant charge checked, capacitors and contactors tested, condensate drain cleared, airflow measured, thermostat verified, and every reading recorded. It is the same thorough visit as annual AC maintenance — this page is where tune-up intent lives, so there is one place to find it.
The timing matters more than the name. Fort Collins averages only 624 cooling degree days against 5,797 heating degree days — a heating-dominant city where the cooling system works a short, intense season. A capacitor that survived last July may not survive the first hot afternoon of this one, and a coil that loaded up with dust and wildfire smoke last preparing your AC for Fort Collins summer heat will not clean itself over winter. At 5,003 feet the system already gives up roughly 10–20% of its sea-level capacity, so there is no spare margin for a dirty coil or a low charge. A March or April tune-up also means parts, if anything is found wearing out, can be ordered without a heat wave pressing on the schedule — and it means the first hot weekend of June is not the first time the system has run since September.

What's included
What our AC tune-up includes
Every tune-up follows the same checklist, and you get a written record of the readings. Here is what is on it.
Refrigerant charge verification
Charge is checked against the manufacturer's specification. Low charge means a leak, and a tune-up is the visit that finds it in spring rather than in July, when it becomes a no-cool call.
Capacitor and contactor testing
Capacitors weaken gradually, then fail on the hottest day of the year. Testing under load in spring catches the ones that will not survive the season.
Condensate drain service
The drain is cleared, the trap and pitch are checked, and the float switch is verified. A clogged drain is the quiet failure that becomes a ceiling stain, and spring is the cheap time to find it.
Airflow and filter check
Airflow is measured and the filter inspected. Undersized returns and long-overdue filters are a common cause of frozen coils in older Fort Collins homes, and both are cheap to fix in April.
Thermostat and safety controls
The thermostat's call for cooling, its wiring — including the common wire smart thermostats need — and the system's safety controls are all verified before the season starts.
How it works
How our ac tune-up process works
Call (970) 932-2324 any time. March to April is the ideal window; the visit is useful any time before the cooling season peaks, but the earlier it happens, the more time there is to act on anything found.
We work through the checklist — coils, charge, electrics, drain, airflow and controls — cleaning as we go and recording readings rather than guessing.
You get a written record of what was found, what was cleaned or adjusted, and anything wearing out, with the condition explained in plain terms.
Anything beyond the tune-up is quoted separately. Nothing is replaced without your approval.
The system is run and tested before we leave, so the first hot day of the year is not its first test run since September.

Tools & methods
Tools and methods we use on every job
Coil cleaning equipment
Purpose-built coil cleaner and rinse for indoor and outdoor coils, restoring heat transfer without damaging fins.
Manifold gauges
Refrigerant pressures checked against specification to confirm charge and compressor health.
Multimeter and capacitor tester
Electrical components tested under load, so a weakening capacitor is caught before it fails.
Airflow measurement
Supply and return airflow checked against the equipment's rated range.
Drain clearing tools
Condensate lines cleared and flushed, with trap and float switch verified.
Thermal imaging camera
Temperature differences across coils and ductwork that reveal restricted airflow and hot spots.

April tune-up on a Campus West rental
Student rentals around Campus West see heavy summer use and long gaps between filter changes, and turnover season means a system can sit unchecked for a year. A spring tune-up before the summer tenants arrive catches the filter, the drain and the capacitor before they become a no-cool call in July.
What good work addresses: a full checklist visit in March or April, with the filter schedule and drain condition noted for the landlord so the next turnover starts from a known baseline.

Tune-up after a smoke summer in Midtown
After a wildfire smoke season, filters are loaded and coils have been pulling fine particulate for weeks. Midtown's 1950s–1970s homes, many with cooling added years after construction, are the ones where a loaded filter most quickly becomes a frozen coil.
What good work addresses: filter replacement, coil cleaning and an airflow check in spring, so the system enters the new season clean instead of carrying last summer's load into it.

First tune-up on a new Rigden Farm system
Rigden Farm's 2000–2011 homes are hitting their first replacement wave, and many of the systems still running have never had a recorded tune-up. A first visit establishes the baseline — charge, airflow, drain and controls — so every later visit can be compared against it.
What good work addresses: recording the readings while the system is still in good shape, and flagging the first signs of wear on a capacitor or contactor before they become a breakdown.

AC tune-up questions we answer every week
The tune-up is a small spring job with an outsized effect on summer reliability. These are the questions we hear most.
Ask a pro →How often should I schedule an AC tune-up?
Once a year, in spring — March to April. Fort Collins has a short, hard cooling season and a long idle winter, so a spring visit catches winter deterioration before the heat arrives. Heat pumps, which run year-round, need a twice-yearly visit.
What does a tune-up actually include?
Inspection, cleaning and testing: coils cleaned, charge checked, capacitors and contactors tested, drain cleared, airflow measured and thermostat verified, with readings recorded. It is the same thorough visit as annual AC maintenance — this page is the one place tune-up intent lives on this site.
How much does an AC tune-up cost in Fort Collins?
Contractor-published Fort Collins tune-up prices ran $80–$150 in 2026 (Cool Ducts, Allen Service), and $80–$200 across Northern Colorado (Compass). Those are contractor-published figures from November 2026 research, not a quote — your price depends on the system and what the visit finds.
My AC worked fine last summer — do I still need one?
Yes, and that is exactly the point. Capacitors weaken silently, coils load up gradually, and charge leaks slowly. A tune-up finds all three while they are still small jobs; skipping it is how a system that worked fine last August fails on the first hot afternoon of June.

Once a year, in spring — March to April is the shoulder-season window the research points to. The cooling season runs June to September and peaks in July, so a spring tune-up catches winter deterioration and summer wear before the system is asked to run flat out.
In Fort Collins they are the same job: a spring inspection, cleaning and testing visit. This site keeps tune-up intent on this one page and maintenance on the AC maintenance page, so you will not find two different versions of the same service. Book either name and you get the same thorough visit.
15–20 years (Balance Point, November 2026 research). A yearly tune-up is the main factor that pushes a system toward the top of that range: clean coils, correct charge and tested electrics reduce the cycling stress that altitude and hot afternoons already add.
