Do You Have a Winterized HVAC Unit? Here’s How to Tell.

A winterized HVAC unit is one that’s fully prepared for unpredictable Indiana weather. Whether it’s a furnace in regular daily operation or a central air conditioner that’s mothballed until next spring, both units are subjected to conditions that can damage components, degrade performance, and lead to expensive repairs.

First, seasonal HVAC preventative maintenance by a certified technician should be scheduled to provide an inspection of all components — both heating and cooling — as well as specific furnace tuneup procedures and a critical system safety check.

In addition, here are some basic steps associated with winterized HVAC units. Most are DIY for the typical homeowner.

Furnace Components

  • Any items stored in the furnace closet or otherwise near the unit over the offseason should be removed to prevent a fire hazard.
  • Test all smoke detectors and carbon monoxide detectors in the house. Install new batteries annually.
  • High-efficiency furnaces with AFUE ratings above 90 produce liquid condensate that is discharged through a pipe that extends to the outdoors. To prevent ice formation, make sure the drain pipe is properly slanted and that there are no obstructions so that condensate flows freely.

Air-Conditioning Unit

  • At the outdoor component of the central air conditioner, clear away any fallen leaves, sticks, or other debris accumulating on the unit.
  • Squirrels, rodents, or other animals may occupy the outdoor AC during winter. Some chew internal electrical wiring and damage components. Verify that side panels of the AC are secure and that there are no openings that allow intruders to gain access to the unit.
  • Consider installing an AC cover for maximum winter protection. These are commercially available in standard sizes at home centers and other outlets.
  • Tree limbs extending over the outdoor AC may drop heavy ice that impacts the unit, causing damage unless you have a winterized HVAC unit. Plywood cut to size and placed atop the unit offers extra protection.

Winterized HVAC components are ready for whatever the season may bring. So are the professionals at Paitson Bros., now serving Terre Haute for more than a century.
