Residential preventative maintenance

Avoid Unexpected Repairs with Preventative Maintenance for Your Home

Archie Johnstone Plumbing & Heating has designed a preventative maintenance program that we hope will save homeowners like you money in the long run by identifying and, whenever possible, preventing equipment failure. We don’t want you to be stuck with the unpleasant consequences of a boiler or air conditioning unit that has broken at the worst possible time, so we inspect your systems, make note of any equipment deterioration and then talk with you about the cost of replacing or repairing worn parts.


By establishing a service contract with AJPH, you will enjoy a number of benefits:


  • A more comfortable home
  • Units with increased efficiency and capacity
  • A decrease in the likelihood of system failure
  • Reduced wear and tear on all systems
  • Problems identified before they become major issues
  • Lower energy bills


Archie Johnstone’s certified technicians will check all of the following, as applicable:


  • Operating pressures
  • Refrigerant charges
  • Filter condition/change filters/clean filters
  • Compressors
  • All motors, indoor/outdoor
  • Electrical connections
  • Belts, sheaves and bearings
  • Both evaporator and condenser coil condition
  • Heat exchanger condition
  • Manifold gas pressure
  • Limit switches
  • Ventor motors
  • Condition of burners
  • Thermostat operation
  • Boiler tubes and fins


After we complete our inspection, we will provide you with a written report of our findings. That way, you can clearly see what matters need your attention in the near future, and you can focus your budget accordingly. We perform equipment audits upon request. Call today to schedule preventative maintenance for your home’s mechanical systems!
