Between the Seasons: How to Handle Your Home’s HVAC System During Up-and-Down Temps

Posted On March 24th, 2019 by Lanz HVAC

We just passed the vernal equinox - when Winter is done and spring has sprung - as we write this Lanz Heating & Cooling blogpost in our hometown of Champaign-Urbana, Illinois…and as usual this time of year in Central Illinois, the weather can’t make up its mind. Warm? Cold? How about both in the same day?

One night the temperature can be in the 20s, and the next day rise into the 60s. This is life in the Great Midwest. We’re used to wild temperature swings from day-to-day, or even day-to-night, when it’s changing seasons like it is now. But homeowners in Champaign, Piatt, Douglas, Ford, McLean, Iroquois and Vermilion County know that volatile temps can put a home’s Heating, Ventilation & Air Conditioning (HVAC) systems to the test.

So, how can your family stay consistently comfortable when outside the mercury is rising and falling like a yo-yo...while still keeping your energy costs reasonable? Since 2002 when we opened for business in the residential HVAC service industry, Lanz Heating & Cooling has pretty much seen it all. In this blog we’d like to pass along a few smart tips to stay comfortable between the seasons:

Use a programmable thermostat. Quoting from our own blogpost Wintertime HVAC FAQs: Keeping Your Home Warm For the Holidays: “Installing and programming an automatic [programmable] thermostat is a high-tech, proven way to control your home’s temperature on an hourly basis, letting you save energy (therefore money) while everyone stays comfortable at peak times of the day.”

A programmable thermostat is a big help when temps might approach 70° by day and sink into the 30s overnight. If your home is equipped with one, program your thermostat to raise the house temperature two or three degrees when it’s warm, but then lower it a couple notches when it’s cool. (This is generally an excellent energy-efficiency tip, any time of year.)

Mind the gaps. Your home is a fortress against the elements - at least, to some extent. A well-insulated house is like a large heat-trapping box. Look into whether your home needs additional insulation in the attic and exterior walls, as well as sufficient weather-stripping around doors and windows.

Keep your HVAC system in top shape. A few measures homeowners can take to help their HVAC units perform at peak potential:

  • Keep branches, leaves, toys, debris, etc., off and away from the outside condenser coil, housed within that big block bolted outside your house.
  • Swap out any filters - air filter, furnace filter - in your HVAC system’s indoor components.
  • Dust off the intake registers and keep vents clear.
  • Call Lanz Heating & Cooling at 1-800-AIR-REPAIR to keep your HVAC working on a regular maintenance schedule - or when anything doesn’t sound, feel or smell right with your home’s heating and air conditioning systems.

All of us at Lanz Heating & Cooling Inc. wish everyone a happy and comfortable Spring. Please give us a call whenever it’s time for a regular maintenance checkup of your home’s A/C unit and HVAC system, or if your air-quality systems aren’t performing like they should.
