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
- The ability to save money with improved efficiency
