Year-Round HVAC Maintenance Checklist

(And How to Get High Quality HVAC Replacement Parts Fast)

As an HVAC technician, it’s a given that you will spend a great deal of time troubleshooting, servicing and maintaining residential and commercial HVAC systems. Here’s a useful HVAC maintenance checklist you can use as a guide to provide the best service to your clients all year long.
  Check Filters
Filters become clogged with dirt, dust, and debris. Dirty filters can cause damage to HVAC system components. Checking and changing dirty filters is one of the first steps to making sure your clients' HVAC systems will function properly and reduce the chances of you having to make another service trip prematurely.
  Inspect Furnace Control Boards
As the brain of the HVAC system, checking the furnace control board as a part of routine maintenance is no doubt a must. In many cases, if the control board fails, a total control board replacement is required. Faulty control boards must be replaced with a sense of urgency as the system is effectively rendered useless when the control board is down.  
  Test the Draft Inducers
Checking the draft inducer is important for making sure clients' furnaces run safely. It clears out any leftover combustion gas from previous cycles and continues to provide oxygen during the current heating cycle. A properly running draft inducer will also improve the efficiency of HVAC systems and should be a part of your maintenance checklist.
  Boiler Parts and Accessories
For HVAC systems that use a boiler to heat a home or building, there are a number of boiler controls that can cause it to work improperly or inefficiently. Intermittent heat can be due to broken diaphragms, faulty valves, a broken thermostat, just to name a few. A faulty pressure relief valve can be a common cause of low water pressure. The bottom line is that a boiler is an essential part of providing heat to a space and most certainly should be checked as a part of your maintenance HVAC services. 
  Gas Valves
VR8300-2 Gas Valves

Gas valves should always be a part of any maintenance because any defects could pose a potential safety hazard to the occupants in and around the building or home. If you find fault with a gas valve in any system you are checking, more than likely the entire gas valve will need to be replaced. 

  Ignition Modules
780 Series Hot Surface Ignition Module
If the furnace ignition module isn't working correctly in an HVAC system, the furnace blower will not be supplied with power. This is an essential component during the coldest winter days. It may be possible that the ignition module will signal an error by activating a light on the module. If not, manual diagnostics may be required. 

Get the Parts You Need When You Need Them

Using this checklist as a guideline will help ensure that your clients' HVAC system is running optimally. You only provide the highest quality services to your clients, so it is only natural that you only install the best replacement parts.
