What You Get on Your Visit

Your heating and cooling system is a significant investment. The size of your home, HVAC usage patterns, and energy efficiency preferences matter. We account for all of them during equipment installation and replacement.

Our process starts with a home comfort system design visit that includes these steps:

  1. Full evaluation of your current HVAC system, thermostat, and electrical.
  2. Ductwork inspection, airflow assessment, and review of comfort issues.
  3. Professional sizing and system design recommendations.
  4. Utility bill and efficiency review (current vs. modern system).
  5. Written Good / Better / Best options with clear pricing and payment choices.

If you choose to move forward within 60 days, 100% of the visit fee will be applied to the new system installation.

  • Pam C

    Another great experience with On The Mark Heating and Air! Cesar came out to do a yearly maintenance check of our furnace. He found that our thermostat was outdated and needed to be upgraded. It was not allowing our furnace to run at the two-stage capacity it was made for to run efficiently.

  • Lauren K

    We’ve had excellent service from Chris multiple times; he’s very knowledgeable about our system. We may need our furnace replaced soon, and we will be using On the Mark to do it. My parents needed a full system replacement, and On The Mark made it very easy for them.

  • Julie M

    On the Mark installed a new furnace and AC unit today. Everyone I’ve dealt with during the process has been very courteous and paid attention to details when explaining my systems, clearly answering my questions, leaving things very clean, doing good, neat work, and double-checking everything before leaving. I would highly recommend them for maintenance or replacement.
