AS A SEMI-RETIRED GENERAL CONTRACTOR WITH 45 YEARS IN THE TRADE, I HAVE THE LICENSES, BONDING AND ABILITY TO DO ANYTHING CONSTRUCTION RELATED. I LIKE SMALLER PROJECTS AND COMING UP WITH CREATIVE SOLUTIONS. AREAS OF SERVICE ARE THE IRON RIVER, WI AREA, ASHLAND AND THE SOUTH SHORE, BUT COULD EXTEND TO THE TWIN PORTS. Spend winter months in Florida

"I'm very pleased. The response was prompt and the repair was expertly done. The communication was perfect and friendly. I highly recommend this company!"

Heating and Air Conditioning questions, answered by experts

Fall and spring are the best times of year to purchase an air conditioner, furnace, or other HVAC components. In fact, by shopping during these periods, you could save 10% to 15% on an AC unit. For HVAC professionals, spring and fall are less busy than summer and winter, when extreme temperatures create an urgent demand for heating and cooling.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

No, a licensed local AC repair technician must replace AC coils due to the need to handle hazardous refrigerants. Attempting DIY poses risks to your personal safety, as most refrigerants are flammable and toxic. You also risk voiding your warranty with the HVAC company and causing damage to the unit.

Not necessarily. Some portable air conditioners may be vented out a door, wall, or ceiling—or even into another room. It’s not necessarily dangerous to run a portable air conditioner without venting it, but it is counterproductive since the unit needs to vent the heat in order to cool the room down in the first place. Without venting your portable AC unit, you’re essentially running a dehumidifier and increasing the temperature in the room.
