HVAC Technician with a checklist


Preventative maintenance is the best way to extend the life of your current equipment. We offer seasonal maintenance checks as well as Preventative Maintenance contracts. With a contract, you receive the additional benefit of lowered repair costs and priority scheduling if your system goes out during peak seasons. Each season, you will receive a reminder post card in the mail. You can call to setup your maintenance appointment or contact us.

Whether you choose seasonal maintenance or sign up for a yearly Preventative Maintenance contract, maintenance includes:


  • Operating check of compressor(s)
  • Refrigerant pressure check
  • Inspection of voltages, amperages, and inspection of fan belt(s) and blades
  • Inspect and secure electrical components (disconnect, capacitors, etc.)
  • Clean condenser as needed
  • Inspect and clear condensation drains (primary and secondary)
  • Inspect drain pans
  • Inspect evaporator coils
  • Inspect thermostat operations


  • Gas pressure check (for gas powered furnaces)
  • Inspect pilot operation
  • Monitor flue draft for Safe Operation
  • Inspect heat anticipator settings
  • Inspect thermostat operations
  • Inspect heat exchanger and burners – vacuum and adjust as necessary

Air Conditioner Maintenance in Allen, TX 75002

“Montgomery HVAC is the company to call when you need someone you can trust.
We have lived in Allen for nearly 18 years. During that time we have encountered companies which will try to upsell to the extent that they have unplugged a system to make us believe we needed to a new unit.
You will never have that problem with Montgomery, They are honest, prompt, respectful, efficient and very capable. They will provide options and will always stand behind their work. Call Betty, she'll get someone on the job right away.”

“The appointment was scheduled for 2PM. Dwayne arrived at our home 1:55PM. That's about a close to the appointed time as one can get!!! Dwayne attended to his duties commencing with the unit in the attic and than the outdoor unit. We discussed the service that was performed as was documented on the check-list. Dwayne appeared to be very efficient in his work practices and was enjoyable to talk with. I will anticipate continuing our working relationship with Montgomert HVAC in the future and will in-fact attempt to have Dwayne respond to any of our HVAC related needs”
