The HCA Membership Benefits
Our Martin-Jetco Heating HCA includes two visits a year: one in the spring, and one in the fall. During our visit, we will clean your air conditioner or furnace (depending on the season), check your system for potential problems, and make sure your system is ready to go for the coming season. Should our technicians have any major concerns, they will address them with you and help you decide the best option, whether it be a repair, upgrade, or complete system replacement. This service is required by most manufacturers in order to honor your warranty.
In addition to this service, our HCA customers receive plenty of other perks, including:
- Priority service
- Discounted diagnostic fee on all service calls (during office hours)
- 20% off parts and labor service repairs*
- No overtime fees

“I love my new system, I’ve experienced both seasons and have been both toasty warm and chilly cool.”- Steven

“We have been with Martin-Jetco since purchasing our home in 2006 when we had our system changed from radiator heating to forced air, and have been completely satisfied with their work and service.”- Kathy D.

I spoke to a technician over the phone to try and troubleshoot some problems I was having with a reverse polarity code. Nothing was working. Not soon after, Chris shows up. Does a quick diagnostic and finds my board is fried. He leaves to gather material and is back quickly to install the new board. As most might know, once you fix one problem...you find another. Chris made some quick adjustments and got me running some heat in this house so my dog doesn't freeze to death. Thanks to Eric, Doug and Chris for all that you do. And those nice people in your office, who are always so understanding and helpful.- Cory A.
