When the April showers begin to fall, we know it’s time to look at that spring maintenance list so we have compiled some of the key checkpoints and troublesome areas that you should look over during this month.

For the residential consumer, start here:

  • Did you put a coil blanket on your unit for winter? It’s time to take that off.
  • Do a visual inspection of your outside HVAC unit. Are there any broken parts or holes that seem glaring?  Is it time to clear debris, such as leaves, from the outside of the unit?  The system coils may have pollen or dust that can be wiped off or take hose and run it over the areas of muck.
  • Inspect pipe insulation, and outdoor panels.  Replace or call for repair if you see unusual tears, bends or missing areas.
  • Once inside, don’t forget that dehumidifier.  Check and clean it.
  • Clean vents and grills that may have been covered with dust, and change air filters. For many, this should really be a monthly task, dependent on your style of filter and the age of your unit.  This actually lowers your energy consumption up to 15%.
  • Piping on the suction line brings the cool refrigerant back to the compressor in the outdoor unit, so there could be damage.  Even sun rot could have occurred last summer, causing a problem at the beginning of this season after a hard winter.
  • Once the temperature requires air conditioning, don’t forget to check the coil “condensate” drain.
  • A tripped circuit can be a sign of a problem, especially if it continually trips.  Call for one of our technicians.
  • Get a full, professional inspection if you have any concerns, or experience a lack of heating or cooling.

 

For the commercial client, start with:

  • Dirt and leaves could be encroaching on a particular outside unit, so do a walkaround outside of your commercial building and remove debris.
  • Consider a lube job for your indoor HVAC component parts and inspect evaporator coils, and blower fans.
  • Calibrate your thermostats, and make sure the settings are correct.
  • Clean out drain lines. What type of debris is sitting in areas you just haven’t checked in months? If the area is prone to algae growth, then use an appropriate solution for removal.
  • Check all refrigerant levels. If it is too low, the unit will not function as the weather changes and requires you to go from heating to cooling.
  • Make sure all electrical outlets are working and that there are no faulty switches or extension cords in the region. It’s the little things that can ruin functionality in a large scale operation.
  • Air duct cleaning can make a difference as you enter the next season

When in doubt–i.e. the temperatures do not seem in sync with what the settings are–call a technician to begin work.  Better to be safe than sorry.
