VIP HVAC Maintenance Plans in San Marcos, TX
Save Money with an HVAC Maintenance Plan
Investing in annual HVAC maintenance can help you save money by:
- Maximizing your HVAC system’s efficiency
- Reducing the likelihood of breakdowns
- Decreasing your utility bills
Yearly maintenance also reduces your costs by extending your system’s lifespan, so you don’t have to worry about replacing it anytime soon. In the event of a breakdown, annual maintenance helps to keep your manufacturer’s warranty valid, which can lower your HVAC repair bill.
Enrolling in a maintenance plan can save you even more money in the long run!
When you sign up for our plan—starting at $249/year or just $20.75/mo per system*—you’ll get:
- 2 maintenance inspections per year with a full breakdown of findings and recommendations
- 15% OFF on all repairs
- Priority scheduling and to be able to jump in line ahead of non-priority customers
- Free premium charges
- Inflation protection
- A transferable agreement (e.g., if you move or sell your home)
*Cost includes the first system only. Ask us about costs for multiple systems ($229 for any additional systems) and our multi-year discounts
