Maintenance checklist for the well-being of your HVAC system. Dallas TX

When you live in Texas, you gain a certain appreciation for your air conditioning system. With temperatures consistently in the 90s (at least!), a consistently cool home is the peace of mind we can’t afford to fail us.

(By the way, have you ever been curious about the genius to whom we all owe a debt of gratitude for inventing air conditioning? You can thank a Yankee.)

And while home systems aren’t as easy as “set it and forget it,” by performing annual maintenance for your HVAC system, you can pretty much relax knowing that you’ll make it through another 9-month summer (we love ya’ DFW!) without breaking a sweat.


  1. Clean and adjust thermostat
  2. Check and tighten loose connections
  3. Check and clean condenser
  4. Check refrigerant charge
  5. Monitor voltage and amperage draw
  6. Inspect inside cooling coil if accessible
  7. Monitor air conditioning cycle
  8. Clean primary and secondary drain lines
  9. Monitor and adjust blower components
  10. Check operating pressures
  11. Install algae tablets
  12. Check suction line insulation
  13. Check and/or replace filter

Check these boxes at least two months before you expect to need your cooling. After all, nobody wants to be surprised when the temps start to rise and your home’s HVAC  system isn’t working. (And if you have small children or elderly people living with you, no heat can mean more than just a few extra fans, it can be a serious health risk.)

If you regularly maintain your Cooling system and still struggle to keep cool, you may not have the right sized system. Find out the right size for your AC unit here.
