A New Hampton summer is no time for your air conditioner to quit. When the house won’t cool down, a few quick checks can save you a service call, and knowing the warning signs tells you when it’s time to bring in a pro. Here’s how to tell the difference.
First, Try These Quick Checks Before You Call
Most “my AC stopped working” calls come down to four things you can check in five minutes. Run through these before anything else.
- Thermostat: Set it to COOL and the fan to AUTO, then drop the temperature a few degrees below the room. If the fan is set to ON, it runs even when the system isn’t cooling, so the air feels warm.
- Air filter: A clogged filter is the single most common reason an AC runs but won’t cool. Hold it up to the light. If you can’t see through it, replace it. In our dusty Iowa summers, that’s every one to three months.
- Breaker: Check your electrical panel for a tripped breaker labeled AC or HVAC and reset it once. If it trips again, stop and call us. Repeated tripping points to a deeper problem.
- Outdoor unit: Clear grass, leaves, and weeds within two to three feet of the outdoor condenser, and make sure the fan is spinning when the system calls for cooling.
If you’ve done all four and the house still won’t cool, the problem needs a technician. That’s where we come in.
8 Signs Your Air Conditioner Needs Repair
Geerts Plumbing & Heating repairs air conditioners across New Hampton and the surrounding area, and these are the symptoms we’re called out for most. Catching them early keeps a small fix from turning into a mid-July breakdown.
Warm Air Blowing From the Vents
Air conditioning that blows warm or room-temperature air usually means a refrigerant leak, a failing compressor, or a thermostat problem. Refrigerant is not something a homeowner should handle, so this one needs a licensed technician. We’ll find the leak, make the repair, and recharge the system correctly.
Weak or No Airflow
Weak airflow points to a clogged filter, a failing blower motor, or a duct problem. If you’ve already swapped the filter and the airflow is still weak, the fan motor or ductwork is the likely cause. We inspect the whole airflow path so you’re not guessing.
The House Just Won’t Cool Down
When your AC runs constantly but some rooms stay warm or the thermostat never hits its target, the system is losing capacity. Low refrigerant, a dirty coil, or a compressor on its way out are common culprits. This is the most common complaint we hear during a New Hampton heat wave, and it’s worth a same-day look before the system gives out completely.
Short Cycling
An AC that turns on and off every few minutes is short cycling, and it drives up your energy bill while wearing out parts fast. The cause can be a dirty filter, a bad thermostat, low refrigerant, or a unit that was oversized for the home. We diagnose the reason rather than just resetting it.
High Indoor Humidity
A working air conditioner pulls humidity out of your air. If your home feels sticky and damp even with the AC running, the system isn’t dehumidifying the way it should. That often traces back to a refrigerant issue or a problem at the evaporator coil.
Water Leaks or Ice on the Unit
Water pooling around your indoor unit usually means a clogged condensate drain line. Ice on the refrigerant lines or coil points to low refrigerant or an airflow restriction. If you see ice, shut the system off, set the fan to ON to help it thaw, and give us a call. Running a frozen unit can damage the compressor.
Strange Noises
Grinding, squealing, banging, or rattling from your AC is never normal. It usually means a loose or failing part, a worn belt, or debris in the system. Shutting the unit down and calling for a repair prevents one bad part from taking out others.
Foul or Musty Odors
A musty smell from your vents often means mold or moisture buildup in the unit or ductwork, which hurts your indoor air quality. A burning smell means shut the system off and call right away. We clean the system out and track down the source so your air is fresh again.
Repair or Replace? How to Decide
For most air conditioners under about 10 years old, a repair is the smart call. Past the 10-to-15-year mark, the math changes. If your unit is aging, needs frequent repairs, or still runs on R-22 refrigerant (phased out and expensive to recharge), replacement usually saves money over the long run. A new high-efficiency system can noticeably cut the summer energy bills we all watch climb in July and August. When you’re on the fence, we’ll give you an honest assessment of both paths rather than pushing the bigger ticket. If replacement is the better value, our air conditioning installation team handles it.

Frequently Asked Questions
How often should I have my air conditioner serviced?
Have your air conditioning system serviced once a year, ideally in spring before the cooling season. Annual maintenance catches worn parts, low refrigerant, and airflow problems early, which keeps the system running efficiently and prevents most summer breakdowns.
How much does an AC repair cost in New Hampton?
Geerts Plumbing & Heating offers a $79 AC service call, which brings a technician to your home to diagnose the problem. The repair cost depends on what’s found, and we give you a clear price before any work begins so there are no surprises.
Is it worth repairing an air conditioner that’s more than 10 years old?
It depends on the unit and the repair. A minor fix on a well-maintained 10-year-old system is usually worth it, but if the unit needs frequent repairs, runs on R-22 refrigerant, or has a failing compressor, replacement is often the better value. We’ll assess your system and give you an honest recommendation.
