Transitioning weather systems can play tricks with your HVAC

May 10, 2018

By now, you've most likely experienced 'springish' weather mixed with 'winterish' cold. Some people have been so brave as to open up their homes to air out – signaling what hopes to be a cooler summer. At the same time, and sometimes on the same day, we've shut those winters to keep warm – dodging a cruel practical joke that the weather sometimes plays. In some areas, homeowners have gone as far as switching over to their air conditioners to blast out warm, stale air and in some cases find that something wasn't 'quite right'. Was the fan blowing but without cool air? Did the fan ever turn off? What was the reading on your thermostat? Does any of this sound familiar?

Throughout any year, it's important to keep up with the maintenance on your HVAC system. You may think, "Oh, it's ok – it's just sitting there so it should be fine." Except when it's NOT fine. Usually, homeowners ignore regular maintenance and get a surprise on the hottest and most humid day. Here is a quick checklist to consider as we are straddling the cool months and transitioning into the warmer months of the year:

For homeowners, there are two preventative measures you should always pay attention to:


It sounds simple, but keeping filters replaced twice a year will prevent poor performance and provide optimal efficiency


Check your unit to ensure it's free from debris left over from the Fall months – filters and coils need to be clean in order to operate properly

A qualified technician will ensure your HVAC system is ready for the change in weather. Their checklist includes:

  • Quality of belts and pulleys
  • Clean condenser and evaporator coils
  • Refrigerant levels
  • All electrical connections
  • Drain lines
  • Operation of fan/blower motor
  • Thermostat operation
  • Adequate air flow
