A warm house is hard to ignore. Maybe the air feels weak. Maybe the unit hums but never cools. Maybe it just will not start. Any of these can mean your AC needs a repair visit.
Demandsweeks Heating & Air is a referral service. We do not fix air conditioners. We connect you with independent HVAC providers in the Pittsburgh area. You tell us what is wrong. A provider looks at the system and explains the problem. You hear the price and the plan. Then you decide at your own pace, with no obligation. This page shows what to check first, which signs matter, what repairs cost, and what to ask. Compare, then decide.
AC Stopped Cooling? Start Here
First, stay calm. Most AC problems have a clear cause. Some you can check in five minutes. Others need a trained provider.
If your home is hot and someone in it is young, older, or ill, treat it as urgent. Move to the coolest room. Drink water. Then reach out for help.
Quick Checks Before You Reach Out
Try these simple steps. They cost nothing and can save a visit.
Look at the thermostat
Make sure it is set to "cool." Lower the set point a few degrees. Replace the batteries if the screen is dim or blank.
Check the breaker
Find your electrical panel. Look for a tripped switch labeled for the AC or air handler. Flip it off, then on once. If it trips again, stop. Do not keep resetting it.
Check the air filter
A clogged filter blocks airflow. Pull it out and hold it to the light. If you cannot see through it, swap it for a clean one.
Look at the outdoor unit
Clear leaves, snow melt debris, or storm litter from around it. The unit needs room to breathe. Never open the cabinet yourself.
When to Stop and Get Help
Stop if you smell burning. Stop if you see sparks, hear loud grinding, or find water near electrical parts. Turn the system off at the thermostat. Then ask a provider to look at it.

Signs Your AC Needs Repair
Small signs show up early. Catch it early, and the fix is often smaller.
Warm or weak air
Air from the vents feels warm, or barely moves. This can point to low refrigerant (the fluid that carries heat out of your home), a weak fan, or a blocked coil.
Strange noises
Rattling, squealing, and clicking are not normal. A noise often means a worn part. Running the unit longer can harm other parts.
Smells and leaks
A musty smell can mean mold in the ducts or a clogged drain. Puddles near the indoor unit often come from a blocked drain line. Ice on the coil is another warning sign.
Rising bills
If your power bill climbs and the weather has not changed, the system may be working too hard. A check can find out why.
Short, frequent cycles
If the AC turns on and off every few minutes, something is off. It could be the thermostat, a sensor, or a sizing problem.
What Happens During a Repair Visit
A provider usually starts with questions. When did it stop? What did you hear? Then they check the thermostat, filter, and power. Next they test the indoor and outdoor parts.
They may measure airflow and refrigerant pressure. They look for leaks, burnt wires, and dirty coils. Then they explain what they found in plain words.
Ask for a written quote before work starts. You do not have to say yes on the spot.
Common AC Repairs
These are the jobs providers see most often:
- Capacitor swap. A capacitor is a small part that gives motors a start boost.
- Fan motor repair. The outdoor or indoor fan stops moving air.
- Refrigerant leak fix. The leak is sealed, then the system is refilled.
- Drain line clearing. A clog stops water from leaving the home.
- Coil cleaning. Dirt on the coil blocks heat from leaving.
- Contactor or wiring repair. These parts carry power to the unit.
Older homes may also have aging ductwork or tight spaces around the equipment. A provider can tell you if that adds time.
Repair or Replace?
This is a big question. Here are a few clues that help.
- The unit is more than 12 to 15 years old.
- The repair costs close to half the price of a new system.
- Breakdowns keep happening.
- Your bills keep rising.
- The system uses an older refrigerant that is harder to find.
If most of these fit, ask for a replacement estimate too. Hear both options. Then decide. Replacement has its own page on this site.
Questions to Ask the Provider
Good questions make the choice easier. Try these:
- What is wrong, in simple words?
- Is the price written down, with parts and labor listed?
- Can the part be repaired, or must it be replaced?
- Is there a warranty on parts or labor, and how long is it?
- Will you check the whole system while you are here?
- What happens if the problem comes back?
How to Compare Estimates
Get two or three if you can. Do not look only at the total. Read what each one includes. Look at the parts, the labor, and the warranty.
A much lower price may leave something out. A much higher price should come with a clear reason. A good provider welcomes your questions.
Keep Your Cooling Ready Between Seasons
In cold, snowy places, an AC may sit idle for months. Ice, wet snow, and coastal storms can leave debris and wear on the outdoor unit. Before the first hot week, cover nothing and clear the area. Then run the system for a short test.
If something seems wrong, book HVAC service early in the season. Spring often gives you more choice than a July heat wave.
Protect Your Home and Your Budget
Heating and cooling make up a large part of home energy use. A yearly tune-up can find worn parts before they fail. Changing the filter on schedule helps too.
Some home policies may cover sudden damage, such as a power surge or storm harm. Check your policy. Providers can often help document damage for a claim.
Ready to Take the Next Step?
You do not need to decide today. Describe the problem, hear a plan, and weigh the price. That is how Demandsweeks Heating & Air is built to work.

No obligationAC Repair FAQ
Why is my AC running but not cooling the house?
Common causes include a dirty filter, a blocked coil, low refrigerant, or a failed fan. Check the filter and thermostat first. If air stays warm, ask a local provider to inspect the system.
How much does AC repair usually cost?
Many repairs run from about $100 to $1,500 in the U.S. Small parts cost less. Refrigerant leaks and compressors cost more. Always get a written quote before work begins.
Should I repair or replace my old air conditioner?
If the unit is over 12 to 15 years old and the repair costs near half of a new system, replacement may make sense. Get both estimates and compare.
