Hi! I have been in the HVAC business for over twelve years now. Five years ago I married my wife and moved to Sioux City. We decided to open our own heating and cooling business 5 years ago now. I run the business on my own, which allows me to give my customers my full attention and keep the work I do affordable, compared to my other competitors!

Heating and Air Conditioning questions, answered by experts

Signs that your air conditioner capacitor is malfunctioning include a smell or smoke coming from the unit, a humming or banging noise when it starts, the system shutting off randomly, higher energy bills, and no cold air blowing out of the unit. Additionally, if your capacitor is bad, the air conditioner may not turn on at all. 

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Diagnose whether your HVAC damper is bad by assessing airflow. For a manual damper, close it and run your system. Air should stop flowing through the associated vents. If you feel air, it’s likely a bad damper that requires repair or replacement. Automatic dampers should maintain your desired room temperature. If not, they may be faulty, and you may need to invest in some HVAC repair costs.

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.
