HVAC repairs: DIY or go pro?

August 30, 2024 / Larry Howald

Google is a great invention. Among many other uses, the search engine saves homeowners hard-earned cash when they need to figure out a quick fix or research what’s wrong with something around the house. But when it comes to HVAC repairs, it’s important to understand the differences between a DIY repair versus calling in a trained professional technician.

Howald Heating, Air Conditioning & Plumbing is family owned and operated, with roots dating back to the 1960s. Over the decades, we’ve seen a lot of duct tape, DIY projects gone wrong. Although our techs appreciate the motivation to save and creativity to find a fix, we want to be sure your home is comfortable year-round.

We admit, there are basic DIY fixes that can be done by a homeowner. Here are a couple HVAC repairs you can diagnose and/or do on your own.

  • Replace a furnace filter. This needs to happen regularly. Dirty filters prevent air flow.
  • Furnace gone kaput? Check the thermostat batteries. If they’re out, so is the furnace. Also check your fuse box.
  • Furnace is cycling. Be sure to check the air vents outside your house. If the unit is cycling, chances are something is blocking the air vents.

Call in a pro for HVAC repairs

Manufacturers and professionals, such as Howald HVAC, recommend units be tuned up a couple of times each year. Often a furnace warranty requires it. Lack of maintenance is often the cause of major repairs. An investment in a home HVAC system is thousands of dollars, so investing each year to ensure the system works well is a small cost to ensure you’re not left in the cold on a subzero day or left sweltering in the middle of summer.

If you have the following happening, it’s best to call in a technician.

  • Blower motor isn’t turning on
  • Refrigerant is leaking
  • Coils are frozen
  • Unit cycles off and on (see above, to check for an easy fix)
  • HVAC system emits a smell
  • Weak to no air flow
  • System is making funny noises
