AC just quit on a 95 degree afternoon? Breathe. This fast emergency checklist will help you stay safe, try a few smart fixes, and know when to call for emergency AC repair Denver homeowners trust. If you smell gas, see smoke, or hear sparking, leave the area and call 911 first. For everything else, follow the steps below to rule out simple issues and protect your system while you get help on the way.
Safety First: Quick Rules Before You Touch Anything
Denver heat can spike quickly and indoor temps follow fast. Start with safety.
- If you smell gas, see smoke, or notice sparks, evacuate and call 911.
- Turn off the HVAC at the thermostat and at the breaker if you see smoke, sparking, or scorched wires.
- Keep kids and pets away from the condenser and electrical panel.
- If water is pooling around the indoor unit, switch the system off to prevent further damage.
Golden West provides 24/7 live answering and emergency AC repair. If you are unsure, call 720-613-8880 and we will guide you.
Step 1: Confirm Power to the System
A surprising number of dead AC calls are power related. Check these in order.
- Breaker panel
- Find the breakers labeled AC, Air Handler, or Furnace. If tripped, switch fully off, then on once.
- If a breaker trips again, stop. You may have a short, failed motor, or capacitor.
- Service switch by the indoor unit
- Many air handlers have a wall switch that looks like a light switch. Make sure it is on.
- Outdoor disconnect
- The condenser often has a pullout or breaker under a small cover. Only reinsert the pullout if you are comfortable and it is safe. Do not force anything.
If restoring power does not bring the system back, move to the next checks.
Step 2: Set Your Thermostat to Succeed
Thermostats get bumped or batteries die.
- Set the mode to Cool and fan to Auto.
- Lower the temperature setpoint at least 3 degrees below room temp.
- Replace batteries on battery powered thermostats.
- For smart thermostats, confirm Wi‑Fi and app schedules are not holding the system off.
- Check any safety lockouts or vacation modes.
If the thermostat calls for cooling and nothing starts, you may have a float switch lockout from a clog, a failed control board, or low voltage problem.
Step 3: Improve Airflow Fast
Insufficient airflow will trigger freeze ups and shutdowns. Denver’s late spring cottonwood fluff can clog filters and coils quickly.
- Air filter
- Replace if dirty or older than 60 days in summer. Heavy smoke or cottonwood may require monthly changes.
- Vents and returns
- Open at least 80 percent of supply vents. Keep large furniture clear of returns.
- Ice on copper lines or the indoor coil
- Turn system Off and fan to On for 60 to 90 minutes to thaw. Do not chip ice.
If the system runs after thawing but freezes again, you likely have a dirty coil, blower issue, or low refrigerant. That calls for a pro.
Step 4: Check the Outdoor Unit
The condenser does the heavy lifting. A quick look can reveal simple problems.
- Is the fan spinning?
- If you hear a hum but the fan does not spin, a failed capacitor is common.
- Never stick objects into the fan. This is dangerous.
- Coil cleanliness
- Gently hose from inside out to remove dirt and cottonwood. Turn power off first.
- Physical damage
- Hail is common along the Front Range. Flattened fins restrict airflow and can overheat the compressor.
If the outdoor unit is silent with the thermostat calling, you may have a contactor, capacitor, control, or high pressure switch issue.
Step 5: Clear the Condensate Drain
In many Denver homes, a clogged drain pan trips a float switch that kills cooling to prevent water damage.
- Look for water in the pan or floor around the indoor unit.
- If you have a condensate safety switch, reset it only after clearing water.
- Use a wet dry vac at the drain line outside to pull the clog. A cup of white vinegar monthly helps prevent algae.
If the clog returns quickly, the trap may be misconfigured or the drain line damaged.
Step 6: Try a Safe System Reset
Once you have completed power, thermostat, airflow, outdoor, and drain checks:
- Turn the thermostat Off.
- Turn the AC and air handler breakers Off for 2 minutes.
- Turn breakers On, wait 1 minute, then set the thermostat to Cool.
If the system starts then trips again, call a professional. Repeated restarts can damage the compressor.
When It Is an Emergency and You Should Call Now
Certain conditions signal a real risk to people or equipment.
- Strong odor of gas
- Sparks or smoke from the unit or panel
- Loud or unusual noises like grinding or screeching
- Leaking refrigerant or oily residue at fittings
- AC blowing warm air in cooling mode during a heat wave
- Breaker that trips repeatedly
Golden West responds 24/7 and stocks trucks with common parts so many repairs finish in one visit. We never begin work without your approval.
Special Notes by System Type
Different systems fail in different ways. Here is what to check.
Central AC
- Common failures include capacitors, contactors, fan motors, blower motors, and clogged coils.
- If freezing occurs, leave the fan on to thaw and call for service. Frozen coils can flood floors when they release.
Heat Pumps
- In cooling season, treat like central AC.
- In shoulder seasons along the Front Range, wide temperature swings can expose defrost control issues. If the outdoor unit cycles oddly or ices over, call.
Ductless Mini Splits
- Clean the indoor unit’s washable filter monthly in cottonwood season.
- If a wall head flashes error codes, note them for the technician.
Evaporative Coolers
- If the pump runs but air is warm, check the water supply valve and pads.
- Leaks or electrical smells mean power off and a service call.
Denver Homeowner Edge: Local Factors That Matter
- Altitude and dry air mean strong daytime cooling loads and quick dehydration. Keep water handy when troubleshooting.
- Cottonwood fluff peaks in late spring and can blanket coils in days. Rinse condensers more often.
- Afternoon hail and wind are tough on fan blades and coil fins. Inspect after storms.
- Smoke and dust from wildfires or construction clog filters faster. Shorten filter change intervals.
Local context helps you prevent breakdowns and describe issues clearly when you call.

What Homeowners Are Saying
"Chris, at Golden West, is amazing. He is always happy, friendly and very knowledgeable. When I call with an emergency, someone always shows up to your home the same day. I called several companies and they could not put me on their schedule for 48 hours. That doesn't work when you don't have heat on one of the coldest days of the year. Thank you Golden West!"

Lou, Edgar, and everyone at Golden West Plumbing are very professional and exceeds expectations. I appreciate their knowledge, transparency, honesty, and integrity.

–Paige M., Emergency HVAC
"We needed someone ASAP. ... there was a May heat-wave and our Central A/C unit had died. We needed someone ASAP. When I 1st called in the woman was great, very friendly and understanding. She told me very quickly they were booked solid that day, understandably, it was late Friday morning with all that hot sun happening. As she continued to get my info, I assume she was messaging someone on the other side and advised me they could get someone out that afternoon."
–Sarah O., Emergency HVAC
"Alec came out to our house within an hour of being called on Easter Sunday after water had flooded our basement. He quickly found the problem was a supply line and called out another member of the team. They came up with a plan, gave us a quote and showed up on Monday morning. They dug down and replaced the line and we had water back just over 24 hours from losing it. They were friendly, professional and really took care of us from start to finish. Can’t recommend them enough!"
–Jacob C., Emergency Service
