A humming outdoor unit with a fan that will not turn is the call we get most in July in Broomfield, CO, and the cause is usually a failed run capacitor. That inexpensive component starts the compressor and fan, fades for years without complaint, and then quits under peak load. It is far from the only suspect, though. Contactors pit and stop passing clean power, condenser fan bearings dry out, small refrigerant leaks drain away cooling capacity, and evaporator coils ice over when a clogged filter strangles airflow.
At Broomfield HVAC, each cooling call starts with measurement. Capacitors are metered against the rating on the label. Amp draws on the compressor and fan motor are compared to the data plate. Refrigerant charge is judged by superheat and subcooling, not by pressure readings alone, and any icing prompts a look at the evaporator coil, blower wheel, and filter. This matters because one warm-air complaint can hide four different faults at four very different prices, and a refrigerant top-off that ignores the leak is just a short-term rental on cold air.
Central air, heat pumps running in cooling mode, and ductless mini splits from every major brand are all in our wheelhouse. Because our trucks carry capacitors, contactors, fan motors, hard-start kits, and condensate pumps, most AC repairs are completed the same visit. If the compressor has failed on an older system, we tell you so directly and show you the numbers on repairing versus replacing. Call (970) 602-4976 for fast AC repair in Broomfield.

How Much Does AC Repair Cost in Broomfield?
The typical AC repair in Broomfield costs $150 to $650. Small electrical parts like capacitors and contactors sit at the low end, while refrigerant leaks, coils, and compressors cost more. Broomfield HVAC diagnoses the problem first and gives you a written price before any work starts.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Capacitor replacementThe most common AC failure; outdoor unit hums but won't start | $150–$400 | Most common repair, usually same visit |
| Contactor replacementWorn relay that stops the condenser from starting | $150–$350 | Burned or pitted switch that powers the outdoor unit |
| Condenser fan motorOutdoor fan stops, compressor trips on high heat | $300–$700 | Outdoor fan stops, compressor trips on high heat |
| Refrigerant leak repair + rechargeVaries with where the leak is and how much charge is lost | $300–$1,500 | Depends on leak location and refrigerant type |
| Evaporator coil replacementCorroded or leaking indoor coil | $1,000–$2,500 | Corroded or leaking indoor coil |
| Compressor replacementLargest single repair; often weighed against a new system | $1,500–$3,000 | Largest single repair; often weighed against a new system |
Ranges are typical for these repairs; you get an exact quote before any work starts.
Factors That Change the Price
- The age of the system and whether parts are still readily available
- Refrigerant type, because R-22 recharges are much more expensive
- Timing, such as same-day or after-hours service versus a scheduled visit
- Access to the equipment, like rooftop units or tight attic air handlers
When a quote climbs toward the cost of replacement on an older unit, we'll lay out repair and replacement prices together, with no pressure either way. Call (970) 602-4976 for a quote.
When to Call for AC Repair in Broomfield
The sooner you notice these red flags, the easier and cheaper the problem is to resolve. Here are the most common indicators that it's time to call a professional:
- Puddles near the air handler or water stains on the ceiling beneath it
- Vents blowing air that is barely cooler than the room
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Clicking or humming outside with no fan movement
- Cooling bills climbing while the house stays sticky and warm
- An iced-over evaporator coil or frozen refrigerant lines
- The system short-cycling every few minutes without cooling the house
- A burning smell or repeated breaker trips when the AC starts
Early Action Saves Money
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Don't wait, get Broomfield HVAC on the phone at (970) 602-4976 and we'll take a look right away.

The Benefits of Professional AC Repair
Consider the refrigerant first. It lives in a sealed, pressurized loop, venting it is prohibited under federal rules, and correct service requires gauges, a vacuum pump, and a recovery machine rather than a store-bought recharge kit. Add capacitors that hold a dangerous charge with the power off and a condensing unit fed by 240 volts, and the risks add up quickly. Then there are the diagnostic traps: an iced coil often points to poor airflow rather than low charge, and topping off a system with an unrepaired leak lets moisture and acid slowly damage the compressor while your money leaks out with the refrigerant.
What you get from a pro is a repair that holds. Our experienced technicians find leaks with dye and electronic detectors, base every charge decision on superheat and subcooling, test electrical parts with a meter before condemning them, and measure static pressure and inspect the blower and filter whenever airflow is in question. Parts-cannon fixes tend to bring you back in a few weeks. Ours are built to last through the heat. And if the numbers say replacement is the better call, we show you those numbers honestly, without pressure.
What to Expect From Our AC Repair
We work through a clear, repeatable process so nothing gets overlooked on your property. Here's what you can expect when you choose Broomfield HVAC:
System Diagnosis
We test capacitors, contactor, motors, and amp draws, evaluate the refrigerant charge by superheat and subcooling, and inspect the coil, filter, and condensate drain to find the true fault.
Clear Explanation & Price
Nothing happens without your approval. We explain what broke and why, quote a firm price, and, if the compressor or coil has failed, walk you through repair versus replacement honestly.
On-the-Spot Fix
Since the common summer failures, like capacitors, contactors, and fan motors, are already on board, most AC repairs are wrapped up during the first visit.
Cooling Performance Check
We confirm a healthy temperature split across the coil, verify amp draws and charge, clear the condensate line, and watch a full cooling cycle before we leave.

Smart maintenance is almost always cheaper and easier than an early replacement. Start with these practical measures our team relies on:
- Flush the condensate drain line with the season's first use to head off clogs
- Swap filters monthly while the AC is running hard to keep the evaporator coil from icing
- Have the AC serviced every spring, ahead of the first real heat
- Keep supply and return vents open; closing rooms raises static pressure on the blower
- A new buzz or click at startup often means a weak capacitor, so call before it fails
- Shade helps, but never enclose the outdoor unit; it needs free airflow on all sides
- Keep shrubs two feet from the outdoor unit and gently rinse its coil each spring
DIY vs. Professional AC Repair
Online tutorials may help in a pinch, yet lasting repairs and code-compliant installations usually depend on professional methods and trained technicians. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Refrigerant | Top-offs without finding the leak | Leak found and fixed, then charge weighed in |
| Electrical Safety | Live 240V wiring and a charged capacitor | Circuits tested dead before any work |
| Frozen Coils | Same ice, again and again | Airflow or charge problem identified and fixed |
| Diagnosis | Picking a likely part and hoping | Meters, gauges, and temperature clamps |
| Parts | Parts that are almost the right rating | Ratings matched to the data plate |
| Outcome | Short-lived relief | Tested and confirmed under load |
