Say you step inside after a long day and the air feels heavy. The vents hum, but nothing cool comes out. Dinner, homework and bedtime are all still on the schedule. A broken AC shouldn't take over the whole evening.
Oldestgerman Heating & Air is a referral service. We don't do the repair ourselves. We connect homeowners in the Aurora area with independent local providers who diagnose the problem and fix it. This page walks you through what to check first, what a visit looks like, what common repairs involve, and how to keep notes and photos so estimates go smoothly. Request a callback to check provider availability, or request an estimate when you have a minute.
Say Your AC Quits on a Hot Afternoon
Picture it. You walk in, set your bag down, and the house feels thick and stale. The vents are blowing, but the air is warm. Dinner is in an hour. Nobody has time for a long mystery. So here is the short plan: run a few safe checks, gather some notes, and reach a provider in our network.
Try These Quick Checks First
Some AC problems are small. Before anything else, run through this list:
- Set the thermostat to cool and a few degrees below the room temperature.
- Swap the batteries if the thermostat screen is dim or blank.
- Look at the breaker panel for a tripped switch.
- Slide out the air filter. If it looks like gray felt, airflow is choked.
- Walk to the outdoor unit and clear leaves, grass clippings or storm debris from around it.
If nothing changes after a short wait, switch the system off at the thermostat. A struggling unit that keeps running can turn a small repair into a bigger one.
Turn It Off When You See These
Some signs mean stop. Ice on the copper line. A burning smell. A breaker that trips again right after you reset it. Water pooling near the indoor unit. A loud grinding or buzzing from outside. Shut the system down and keep your hands off the panels. Then Request a callback to check provider availability.
When It Counts as Emergency AC Repair
A warm house is annoying. It can also be risky. If someone at home is elderly, very young, pregnant or on medication that makes heat dangerous, treat the problem as urgent. Pets count too. Many providers can respond quickly to urgent cases, though availability varies by day and by provider. Say plainly who is at home when you ask for help.
Snap It, Note It
Here is a small habit that pays off. Before anyone touches the unit, take a few photos. Get the outdoor unit, the indoor unit, the thermostat screen and the label with the model and serial number. Add any visible damage, like bent fins or water stains.
Then jot down a few lines. When did it stop? Any odd sounds or smells? Did a storm roll through? A provider can read those notes in seconds. They also help if you later talk with your insurance company.
Signs Your AC Needs Repair
Not every failure is dramatic. Watch for these slower hints:
- Air from the vents feels weak or only mildly cool.
- Some rooms stay warm while others are fine.
- The unit runs all afternoon and never catches up.
- You hear clicking, rattling or squealing.
- The air smells musty or sour.
- Your power bill creeps up for no clear reason.
Catching these early can mean a smaller repair and fewer surprises.
Why Sun, Dry Air and Hail Wear Down an AC
Intense sun at altitude bakes outdoor units for months. Dry air carries fine dust that clogs coils and filters. Hail can bend the thin metal fins that release heat. Fast spring melt can leave water and debris around the base of the unit. In newer frame homes, a hot attic can also make the system work harder. None of this is unusual. It just means a yearly check-up from an HVAC service provider is worth it.
What Happens During a Repair Visit
A typical visit is simpler than people expect. The provider asks what you noticed, then looks at the thermostat, filter, indoor unit and outdoor unit. They test electrical parts, check airflow and look at refrigerant pressure. After that, they explain what they found and give you a written quote before the work begins. If the part is on the truck, the repair may finish during the visit. If not, they may need to order it.
Fit the Week
Busy homes need plans, not surprises. Tell the provider which hours work, where the pets stay, and which door has a code or a sticky lock. Ask how long the visit usually runs. Ask whether anyone needs to be home the whole time. A few clear details keep disruption low and the school run on track.
Common AC Repairs
Most no-cool calls come down to a short list of parts:
- Capacitor or contactor: small electrical parts that start the fan or compressor.
- Fan motor: the outdoor fan stops or spins weakly.
- Refrigerant leak: the system cools poorly and may ice up.
- Frozen coil: often tied to a dirty filter or low airflow.
- Clogged drain line: water backs up and can trip a safety switch.
- Thermostat trouble: the system never gets the right signal.
Repair or Replace?
Think of an older system as a car with many miles. One repair may be sensible. Repeated repairs, a failing compressor or an old refrigerant type can tip the math. Ask the provider to compare the repair price with the cost of a new system, in writing. If replacement makes more sense, that has its own page on this site.
Hail and Storm Damage
After a storm, walk around the outdoor unit. Look for dents, bent fins or cracks. Take photos from a few angles. Some policies may cover sudden damage, so check your policy. Providers can often help document damage for a claim, but your insurer makes the final call.
Questions to Ask the Provider
Keep this short list handy:
- Will I get a written quote before work starts?
- Is the diagnostic fee applied to the repair?
- Is the work covered by a warranty on parts or labor?
- How long will the visit likely take?
- Are you licensed and insured in my state?
It is fine to ask. Good providers expect it.
Calm Before the Visit
Leave blinds closed to hold the heat out. Run fans. Drink water. Keep the area around the unit clear so the provider can reach it. Have your photos and notes ready on your phone. A little prep makes the visit feel smooth instead of stressful.
Heating and Cooling Under One Roof
Some homeowners start by searching furnace replacement near me, then realize the AC is part of the same aging system. That is common in homes where heating and cooling share ductwork. Mention it to the provider. They can tell you whether one problem touches the other.
What's Included
Fast Diagnosis
A provider checks the thermostat, airflow, electrical parts and refrigerant to find why cooling stopped.
Written Quote
You get a clear price before any repair work begins at your home.
Common Part Fixes
Capacitors, contactors, fan motors and drain lines are handled during many standard repair visits.
Clear Next Steps
If repair is not sensible, the provider explains your options and the likely cost.
What AC Repair Typically Costs
Prices depend on the part, the age of the system and how hard the unit is to reach. These are typical U.S. ranges only. Always ask the provider for a written quote before work starts.
| Repair item | Typical range | Notes |
|---|---|---|
| Diagnostic visit | $75 – $200 | Often applied to the repair if you proceed |
| Capacitor replacement | $120 – $400 | Common after hot spells |
| Contactor or relay | $150 – $400 | Electrical part, usually a quick job |
| Condenser fan motor | $300 – $800 | Varies with unit size and model |
| Drain line clearing | $100 – $300 | Prevents water backup and shutoffs |
| Refrigerant leak repair and recharge | $200 – $1,500 | Depends on leak location and refrigerant type |

No obligationAC Repair FAQ
Why is my AC running but not blowing cold air?
Common causes include a dirty filter, a frozen coil, a failed capacitor or low refrigerant. Check the filter and thermostat first. If air stays warm, turn the unit off and ask a provider to inspect it.
Is it safe to keep running an AC that is not cooling?
Usually not. A struggling system can overheat or ice up, and a small issue can grow. Turn it off at the thermostat, then have a local provider look at it.
How do I find emergency AC repair near me?
Request a callback to check provider availability, or submit the request form. Tell them who is at home and any warning signs. Many providers can respond quickly, though timing varies by provider.
