Common HVAC Problems and When to Call a Professional

At Lappe Heating & Air, we know how important comfort is for homeowners in Evansville, IN. Nothing throws off your day faster than a furnace that can’t keep up during a chilly night or an air conditioner that fails on a hot, humid afternoon. Your HVAC system is the heart of your home’s comfort, but like any mechanical system, it can develop issues over time.

That’s where we come in. As your trusted partner for HVAC repair in Evansville, IN, we’re here to explain the most common HVAC issues, why they happen, and when it’s time to call a professional.

Common HVAC Problems

Poor Airflow

Weak airflow through your vents usually means something is blocking or restricting circulation. Whether it’s hidden duct issues or worn components, airflow problems quickly make your home uncomfortable. Our Evansville HVAC repair experts can test your system, pinpoint the cause, and get air moving again.

Uneven Temperature Distribution

If one room feels like a freezer while another feels like a sauna, chances are your ductwork or insulation isn’t working properly. Uneven temps are a common problem in older homes around Evansville, and our technicians can make adjustments to balance comfort across your house.

Unusual Smells (Mold & Refrigerant Leaks)

• Strange odors aren’t just unpleasant—they can be unsafe. 

• Mold in ductwork creates musty smells, while refrigerant leaks produce chemical-like odors that signal serious system trouble. 

For safety’s sake, shut the system down and call us for fast HVAC repair in Evansville, IN.

Incorrect Air Temperatures

An air conditioner blowing warm air or a furnace failing to heat is often tied to deeper issues like low refrigerant, compressor problems, or damaged parts. Our skilled HVAC technicians have the tools to diagnose and restore your system safely.

Strange Noises

Your HVAC system shouldn’t sound like it’s falling apart. Rattling, squealing, or banging noises usually mean something’s loose, broken, or failing. Catching it early with professional repair prevents bigger (and more expensive) issues.

Short Cycling

Short cycling—when your system constantly turns on and off—drains energy, drives up utility bills, and stresses your equipment. From faulty thermostats to refrigerant issues, this problem requires professional diagnostics and repair.

Insufficient Heating or Cooling

If your system runs nonstop but still can’t maintain comfort, you might be dealing with thermostat malfunctions or electrical issues. Our Evansville-based HVAC team can quickly pinpoint the issue and restore your system’s performance.

Dirty or Clogged Filters

Filters protect your system, but when they clog, everything else struggles. Beyond restricting airflow, dirty filters can shorten your system’s lifespan. During regular maintenance, we replace them so you never have to worry.

Dirty Ductwork

Dust and debris in your ductwork don’t just lower efficiency—they spread allergens throughout your home. Professional duct cleaning from our Evansville technicians keeps your air clean and your system running smoothly.

Thermostat Malfunctions

Smart or traditional, thermostats sometimes fail. If yours is acting up, we’ll test, recalibrate, or replace it to ensure your HVAC system responds properly.

Blown Fuses & Tripped Circuit Breakers

Electrical issues often strike during extreme Evansville weather. While a breaker trip might seem small, it can indicate larger HVAC strain. Our certified repair technicians will inspect and fix it safely.

Dirty Coils (Evaporator & Condenser)

Dirty coils make your system work harder, raising bills and lowering comfort. Professional coil cleaning during maintenance ensures long-lasting, efficient performance.

Water Leaks

Pooling water near your HVAC system signals a condensate drain issue. Beyond damaging your home, leaks create mold risks. We handle the repair quickly to prevent further damage.

Negative Pressure Issues

Negative pressure pulls unconditioned air into your home, reducing efficiency and comfort. This complex issue requires professional testing and correction.

Leaky Ducts

Duct leaks waste energy and money. Our Evansville HVAC experts seal ductwork effectively, restoring comfort and reducing your utility bills.
