Heating and Air Conditioning questions, answered by experts

There are likely dozens of HVAC repair companies that service your area, and choosing the right one can be a tricky process. To hire the right HVAC technician, we recommend reaching out to local companies and ask the following questions:

  • Are you licensed and insured?

  • Do you have any third-party certifications?

  • Do you often work on my specific type of HVAC system?

  • Do you provide any warranty for your work?

  • Do you offer maintenance contracts for ongoing savings?

  • How many years of experience do you have?

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. 

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

HVAC replacement doesn't always include ductwork replacement. It depends on the condition of the existing ductwork. You can reuse your ducts if they are in good shape, adequately sized, and meet current standards. However, if the ducts are damaged, poorly designed, or not appropriately sized for the new system, they may need to be replaced or upgraded. HVAC contractors will assess the condition of the ductwork during the replacement process and recommend any necessary modifications or replacements to ensure the new HVAC system operates efficiently and distributes air effectively throughout your home.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.
