Signs You Need AC Repair or Replacement
Our expert technicians can quickly diagnose whether you need repair or replacement. Here are the most common warning signs — if any sound familiar, call us today for fast service.
AC Won't Turn On
Possible Causes: Tripped breaker, failed capacitor, bad capacitor, or thermostat issues.
What to Do: Check your breaker panel for a tripped circuit and reset it once if needed. Confirm the thermostat is set to cool and below the current room temperature. If the unit still won't start — or the breaker trips again — call us right away rather than resetting repeatedly, which can cause further electrical damage.
AC Won't Turn Off
Possible Causes: Stuck relay switch, faulty thermostat, dirty air filter causing the system to overwork, or an undersized unit struggling to reach the set temperature.
What to Do: Check that the thermostat is set above the current room temperature and replace the filter if it's overdue. If the system keeps running regardless, there's likely an electrical or thermostat issue — contact us to prevent unnecessary wear and high energy bills.
AC Thermostat Not Working
Possible Causes: Dead batteries, faulty wiring, miscalibration, or a failing thermostat control board.
What to Do: Replace the batteries first and confirm the display is on. If the unit still won't respond or holds the wrong temperature, the thermostat itself may need to be recalibrated or replaced — call us for assistance.
AC Short Cycling
Possible Causes: Low refrigerant, dirty air filter, malfunctioning thermostat, electrical issues, or an oversized unit.
What to Do: Check that vents are open and unobstructed and that the filter is clean. If the system continues to turn on and off in short bursts, schedule a diagnostic with our team right away to prevent further wear to the system.
AC Running But Not Cooling
Possible Causes: Low refrigerant, dirty evaporator coils, failing compressor, or incorrect thermostat settings.
What to Do: Confirm thermostat is set to cool and unit has been cycling for at least 15 minutes. If AC continues blowing warm air, it's likely mechanical — don't delay contacting us.
AC Fan Not Working
Possible Causes: Faulty capacitor, burnt-out fan motor, broken fan belt, or a tripped breaker isolating the fan circuit.
What to Do: Check that the breaker hasn't tripped and that the thermostat is set correctly. If the outdoor or indoor fan still won't spin, call us right away to prevent the compressor from overheating.
AC Line Frozen
Possible Causes: Restricted airflow from a dirty filter, low refrigerant levels, blocked return vents, or a malfunctioning blower fan.
What to Do: Turn the system off and switch the fan to "on" mode to let the ice thaw — this can take several hours. While you wait, replace your air filter and watch for leaks around the unit. Once thawed, if the line freezes again, call us immediately as refrigerant or airflow issues require a professional fix.
AC Leaking Water or Pooling By Unit
Possible Causes: Clogged condensate drain line, dirty air filter, frozen evaporator coil, or cracked drain pan.
What to Do: Turn the system off immediately to prevent water damage and electrical hazards — then check whether your air filter is overdue for a change, as a clogged air filter is a common culprit. Otherwise, keep the system off and call us right away.
AC Making Loud, Buzzing, or Rattling Sounds
Possible Causes: Loose fan blades, debris inside the unit, failing motor mount, or compressor issues.
What to Do: Turn the system off and call us right away — different sounds can point to very different problems, and continuing to run the unit risks turning a minor repair into a major one.
AC Smells Bad
Possible Causes: Musty odors indicate the presence of mold or mildew, while burning smells suggest electrical issues or a failing motor. A rotten egg smell may point to a refrigerant leak or pest intrusion near the unit.
What to Do: A musty smell can sometimes be improved by replacing a dirty filter, but persistent or unusual odors — especially burning or chemical smells — mean you should turn the system off immediately and call us. Don't run the unit until it's been inspected.

What Your Neighbors Are Saying
AC compressor went out, needed to replace the unit. Quote came in under competitors and installation was done within 48 hours. Excellent service all around, and I'm very impressed with the quality of work. I can literally tell a difference in how the piping is insulated properly and the ductwork above the furnace lines up cleanly and has no leakage. I will be using these guys in the future.
- Michael J.
We called a different company and they never showed. Called Advanced the next morning and they were there that day. AC fixed in less than an hour. Asked if we could get a quote for new furnace and AC unit. Had the quote within a few days. Once we accepted it, we thought it would be a few weeks before installation. It was 2 days. All 3 guys that came were all great. Will definitely recommend them to others and use them in the future.
- Jill K.
Had a great experience with Jeff at Advanced Heating. I will be using this company from now on. Very knowledgeable and this company doesn't take advantage of you. Can't say enough good things about the company and its service. Thank you!
- Patti J.
I called Advanced when our air conditioner stopped working. Jeremy came out that night and worked to get us back up and running. I highly recommend them!! Will be calling them for all our heating and air needs!! Great service.

Frequently Asked Questions
Do you offer same-day AC service?
We are often able to offer same-day AC service, as well as providing 24/7 emergency services for air conditioning repair and other HVAC services.
What are the most common AC failures and repairs?
The most frequent AC issues we see are faulty electrical components, refrigerant leaks, frozen coils, damaged fan blades, bad compressors, capacitor failures, and thermostat malfunctions — many of which are affordable fixes when caught early. Keeping up with regular maintenance can prevent many of these issues before they become costly repairs.
How can I tell if my AC compressor or capacitor is bad?
A failing compressor often shows up as warm air despite the system running, unusual noises like rattling or clicking, or a unit that struggles to start or frequently loses power. A bad capacitor typically causes similar symptoms — the fan or compressor may not start at all, or you might hear a humming sound as the motor tries and fails to kick on. Both issues require professional diagnosis to confirm, so if you're noticing these signs, contact us and we'll get to the bottom of it quickly.
How much does AC repair cost in Omaha?
AC repairs around Omaha can start in the low hundreds, but costs vary widely depending on your type of unit and the extent of the problem. Minor fixes tend to cost less, while major component repairs can cost significantly more. After diagnosing the issue, we'll give you an upfront quote so you understand your costs before we move forward.
How much does AC replacement cost in Omaha?
AC replacement in Omaha can start around $3,500, though prices often run higher depending on unit size, efficiency, labor, and whether you're replacing just the AC or both your AC and furnace. New or updated ductwork will also add to the total. After evaluating your home, we'll walk you through your options and provide a clear quote before any work begins.
Does home warranty cover AC replacement?
Many home warranties cover AC repairs and some components, but replacement coverage varies widely between providers. Some policies offer only partial coverage or exclude replacement due to age, improper maintenance, or pre-existing conditions. We recommend reviewing your policy and contacting your provider before scheduling service — we're happy to work with your warranty company and provide any documentation needed to support your claim.
How long does an AC unit last?
Most AC units last between 15 and 20 years with regular maintenance, though this can vary depending on the brand, how hard the system works, and how well it's been serviced over the years. If your unit is approaching or past the 15-year mark and requiring frequent repairs, replacement is often the more cost-effective choice. Our technicians can help you weigh repair vs. replacement costs so you can make the best decision for your home and budget.
