5 Key Questions to Ask When Preparing HVAC Systems for Winter

By Brian Sodoma, for Service Experts

With autumn coming soon, homeowners will soon be getting ready for the cold months ahead. Cold weather puts additional demand on your heating system. To prepare your heating system for the heavy work it will be doing, routine HVAC maintenance should be on your fall to-do list. It’s vital for your system to operate efficiently in order to reduce the likelihood of repairs at an undesirable or unsafe time, such as during a storm. Here, a skilled technician from Service Experts shares five questions to ask when preparing your furnace for winter.

1. When Should I Schedule My Furnace Tune-Up?

As soon as the cold sets in, many contractors focus on repairs over maintenance calls. Getting your HVAC system tune-up done before the first bite of winter cold means that it will be ready for the season. It’s also important to look for a contractor whose team consists of qualified technicians, said Mike Carson, manager of technical training and field operations support at Service Experts. To further check into a contractor, ask what’s included in their furnace maintenance. Here are a few must-haves:

  • Cleaning burners and ignition components
  • Testing safeties
  • Inspecting the heat exchanger
  • Cleaning and flushing drain lines
  • Examining air filters
  • Testing thermostats

2. When Was the Last Time I Changed My Air Filters?

Summer gets busy, which means it’s easy to forget to change your HVAC system’s air filter. Filters capture dust, pet hair and other airborne debris, so replacing a dirty filter with a clean one enhances your system’s operational efficiency and elevates indoor air quality.

“When you don’t replace the filter, the system needs to work harder to pull in air, which can lead to early failure,” Carson explained. “Some homeowners will choose a cheap fiberglass filter. They’re less expensive, but pleated filters trap more dust and particles. On the other hand, some can be too thick and restrictive. During your tune-up, ask the technician to suggest which filter is best for your system.”

3. Is My Thermostat Ready for Winter?

Your thermostat is the nerve center of your furnace. It’s a good idea to make sure it’s in proper running order by flipping it from cool to heat mode, setting your heating setpoints, checking your schedule on a programmable thermostat and replacing the batteries if necessary. Now, you should turn it on and listen for any unusual noises or indications the system is struggling to engage.

If your equipment is getting older, a smart thermostat is a worthwhile purchase. It can save you up to 20% on each year’s electricity bill. Although a programmable thermostat adjusts settings dependent on the time of day, a smart thermostat also factors in your behavior. Most designs can be connected to your smartphone so that changes can be made even if you are away. For even more safety, more sophisticated models may be linked to smoke alarms and respond to voice commands, among other helpful features.

“A smart thermostat is an inexpensive, but powerful intuitive device for your home,” Carson noted. “The learning curve will be long forgotten once you start enjoying the convenience and energy savings it offers.”

4. Do I Have Any Air Leaks?

Checking your doors and windows for air leaks before the colder weather arrives can save you a headache later. Not only can it cause drafts, making your living space chilly in the winter or warm in the summer, but the cold air can also lower the temperature in your home, forcing your HVAC system to work harder and increase your utility expenses.

If you notice an air leak ahead of time, you can take preventative actions before winter approaches, such as:

  • Replacing old weatherstripping to make sure doors and windows are totally sealed.
  • Re-caulking any cracks.
  • Closing the fireplace damper when you aren’t using it.

“Avoiding wintertime HVAC issues starts months before winter even begins,” noted Carson. “Take the time now to make sure your home is ready so you’re not paying for it later.”

5. Is the Insulation in My Home Ready for Winter?

Roughly 90% of U.S. households need more insulation, according to the North American Insulation Manufacturers Association. That can have a significant impact on your HVAC system, which will be forced to work harder to keep up during times of very hot or cold temperatures. Autumn is an excellent time to look into adding insulation, if you think your home needs more. But how do you know if your property needs more insulation?

“If your attic insulation is less than seven inches deep, it’s inadequate,” Carson said. “Adding more will probably save you another 20% on your energy bill. Inconsistent room temperatures and drafts could also be signs of poor insulation. Services like blower door testing, home energy audits and infrared cameras can help determine where your home may need more insulation as well.”
