HVAC Maintenance Checklist

June 20, 2017

Here’s an easy, doable preventative maintenance checklist to keep your heating and cooling system in top shape.

 

Lack of regular HVAC maintenance results in possible unit failure, equipment damage, safety concerns and of course, increased run time and cost! Our service agreements ensure that your equipment is working at maximum efficiency 24/7.

It’s a good idea to hire an HVAC company like Impact Heating and Air, LLC to inspect and do maintenance on your system every fall and spring. They’ll do things like inspect and clean the wiring and mechanisms of the unit, which is bit more challenging for the average homeowner. But you can prolong the life and increase the efficiency of your system if you follow this simple maintenance plan:


 

 

 

Some of these things you should do immediately; other tasks only need to be done seasonally or once a year.

Steps to a Healthy HVAC System

  • Buy a better filter if you haven’t already. The new high-efficiency pleated filters have an electrostatic charge that works like a magnet to grab the tiniest particles — even those that carry bacteria.
     

  • Replace the filter at least every 90 days. But check it monthly. If it looks dark and clogged, go ahead and change it. If you have pets, you’ll probably need to change every month.
     

  • Make sure there’s at least two feet of clearance around outdoor air conditioning units and heat pumps.
     

  • Remove debris, such as leaves, pollen, and twigs weekly during spring, summer, and fall from top and sides of outdoor air-conditioning units and heat pumps. Don’t allow the lawn mower to discharge grass clippings onto the unit.
     

  • Monthly, inspect insulation on refrigerant lines leading into house. Replace if missing or damaged.
     

  • Make sure unit is level. Annually, ensure that outdoor air-conditioning units and heat pumps are on firm and level ground or pads.Stave off clogs. Annually, pour a cup of bleach mixed with water down the air-conditioner condensate drain to prevent buildup of mold and algae, which can cause a clog.
     

  • Shut off the water supply to the furnace humidifier in summer. In fall (or when you anticipate turning on the heat), replace the humidifier wick filter, set the humidistat to between 35% and 40% relative humidity, and turn on the water supply.
     

  • Never close more than 20% of a home’s registers to avoid placing unnecessary strain on the HVAC system.
     

  • Replace the battery in your home’s carbon monoxide detector annually.

Cooling Specific
  • Clean evaporator and condenser air conditioning coils. Dirty coils reduce the system's ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.
     

  • Check your central air conditioner's refrigerant level and adjust if necessary. Too much or too little refrigerant will make your system less efficient increasing energy costs and reducing the life of the equipment.
     

  • Clean and adjust blower components to provide proper system airflow for greater comfort levels. Airflow problems can reduce your system's efficiency by up to 15 percent.
     

Heating Specific

  • Check all gas (or oil) connections, gas pressure, burner combustion and heat exchanger. Improperly operating gas (or oil) connections are a fire hazard and can contribute to health problems. A dirty burner or cracked heat exchanger causes improper burner operation. Either can cause the equipment to operate less safely and efficiently.
