AC Repair in St. Paul, MN

The Minnesota summer heat brings intense humidity, making the air feel heavy. When the temperature outside reaches over 80°F, a functioning AC helps keep your home comfortable and prevents moisture-related issues, such as mold growth and wood rot, by dehumidifying the indoor air.

If your air conditioner isn’t working, Dean’s Home Services is here to help with professional AC repair in St. Paul, MN. Our certified and insured AC technicians are ready to work with you to keep your home comfortable year-round.

Common AC Problems We Solve in St. Paul

Dean’s Home Services solves several common AC issues in St. Paul and surrounding communities.

Clogged filters

The air filters in your air conditioning system protect the system from dust, hair, dander, and other contaminants. They also catch allergens, pollen, bacteria, mold spores, and more, improving your home’s indoor air quality. Over time, these filters become dirty and need replacement.

If you notice your home is dustier than usual, has poor air quality, or your air conditioner is short-cycling or forming ice on the inside, try changing the air filter. It may simply be an airflow issue.

Electrical problems

Signs your air conditioner has electrical problems include no power, frequent circuit breaker trips, unusual buzzing or clicking, or a burning smell. Electrical issues in your air conditioner often happen because of faulty wiring, unsafe installation, a damaged compressor, or capacitor issues.

Broken capacitor

The capacitor is a cylindrical part of your AC’s outdoor unit that stores and releases electrical energy. If this important part isn’t working, your AC may make a buzzing or humming sound, won’t turn on at all, or blow warm air. Some reasons your capacitor may not be working include power surges, extreme heat, or failure due to long-term wear and tear.

Clogged drain line

When your air conditioner pushes humid air into your home through the cold evaporator coils, water forms and drips down into the AC’s drain pan. This water should simply drain through a pipe or hose outside, or into a drain. If the drain line becomes clogged with mold, algae, or debris, it may overflow and cause water to pool under or around the AC.

Thermostat issues

If your thermostat is the problem, you may notice unresponsiveness or a blank screen, or it won’t accurately read the room’s ambient temperature. It may also “forget” your settings, or you might notice your HVAC never shuts off. 

Common causes of thermostat issues include a dead battery, loose wiring, or a tripped breaker that interrupts power to the thermostat. 

Low refrigerant

Refrigerant is a chemical compound that alternates between liquid and gaseous form inside your AC’s coils. It absorbs and transfers heat from inside your house to outside. If your air conditioner has low refrigerant levels, you’ll notice signs such as reduced cooling capacity, ice buildup on the coils, and higher energy bills as the system works harder to cool your home.

Refrigerant issues are typically caused by a leak. The copper coils may have corroded, or the system may have sustained damage at some point, allowing the chemical to leak. Improper installation can also cause excessive vibration, which can damage the AC valves and seals.

Signs You Need AC Repair 

The most common signs you need air conditioner repair include:

• No cold air: Your AC is running constantly but not cooling your house, or it isn’t producing any cool air at all.
• High humidity: If you see signs of moisture in your home, you may need AC repair.
• Unusual noises: If you hear loud or unusual noises like banging, screeching, buzzing, or humming, something is wrong.
• Short cycling: An air conditioner that turns on and off too quickly without effectively cooling your house may have airflow issues or other problems that require professional care.
• Water leaks: Water leaks often indicate a clogged condensate drain, a damaged drain pan, or an issue with the evaporator coils.
• Refrigerant leaks: Refrigerant leaks should be handled by a professional due to the risk of environmental contamination, illness, and skin damage.
• High energy bills: If your AC is struggling to keep up with your cooling demands, it’ll use more energy and raise your energy bills. 

AC Repair vs. Replacement

When your aging air conditioner starts to break down more often, or fails to provide the home cooling you’ve come to expect, it might be time to consider a replacement. However, if your AC is fairly new and has been operating smoothly until now, it’s a better idea to schedule a professional inspection or repair.

Here are some common signs that it may be time to replace your AC:

• Repair costs are adding up and creating financial stress.
• It’s nearing the end of its 10- to 15-year lifespan. 
• Energy bills rise every time the air conditioner is on. 

Try using the following formula to determine whether it’s time for a replacement: (unit age) * (repair cost) = x. If “x” is more than $5,000, it’s time to replace your system.

DIY AC Repair vs. Professional

Your air conditioner is a complex system connected to ductwork, your electrical system, and an outdoor drainage system. Mechanical parts, refrigerant, and other components should be handled only by an expert. 

Some simple DIY tasks you can safely perform as a homeowner include:

• Checking the air filter monthly and replacing it when it’s clogged or dirty.
• Clearing the area around the outdoor condensing unit of leaves and debris.
• Ensuring vents are unblocked to maximize airflow.
