Frequently Asked Questions

  • What should I do if there is ice on my Air unit?

    More than likely, it’s either low on refrigerant or low on airflow. As a homeowner, replace your filter and allow the unit to thaw out. 


    If the problem continues, call MC Mechanical Heating and Air to schedule an AC repair. We recommend annual air conditioner maintenance to keep your systems in peak operating condition.

  • What is that black stuff on my ceilings and vents?

    The black on your walls and ceilings and the contaminated air your family breathes may be caused by burning candles. 


    To help lessen the amount of soot produced by the candles, keep the wicks trimmed to no more than 1/4 inch in length. 


    However, if you are concerned, call us whenever you like, and a member of our staff will come to take a look.

  • How big of a furnace or air conditioner do I need for my home?

    The only way to size a furnace or air conditioner for your home is to do a heat load calculation. 


    The size (also referred to as capacity) needed is determined by how quickly your home loses or gains heat, not just by square footage.
