Planned Maintenance Program

We recognize the value in keeping a system clean to work at its rated capacity and efficiency.

Deml Heating and Air Conditioning offers a Planned Maintenance program that gives you 3 options for keeping your system at its best for safety and peace of mind. 


  • COOLING PLANNED MAINTENANCE AGREEMENT
  • HEATING PLANNED MAINTENANCE AGREEMENT
  • ANNUAL (COOLING and HEATING) PLANNED MAINTENANCE AGREEMENT 


This is a PRE-PAID service.  Your signed agreement and payment must be received prior to the equipment check. 




Frequently Asked Questions

When the given maintenance season is upon us (heating or cooling), we will contact you to set up a time to come in and go through your equipment. 

As part of your maintenance agreement, we service your equipment and make sure it is running as good as the day it was installed, with clean cabinets and a fresh filter. 


 The cooling season checks start in April or May when the temperature rises enough to check your air conditioning system. We need to have a minimum temperature of 65° or better for at least one solid week before we can properly assess the performance of your air conditioner.  The heating season checks start in September or October as we are readying for the soon to arrive winter.  


One of the keys to planned maintenance is if you prepay for service and you have equipment problems, we have a discount for parts and services for the rest of the season.
