Why HVAC Maintenance Matters

Your heating and cooling systems are just like your car; they need routine service to stay reliable. Without it, they’ll:

  • Run less efficiently
  • Use more energy (higher bills)
  • Be more likely to break down

Save Money With a Maintenance Plan

With an annual service agreement from Control Tech, you get more than just a tune-up—you get peace of mind. Regular maintenance keeps your system running efficiently while saving you money on repairs and energy costs.

What’s Included in Your Plan?

For one low annual rate, you’ll receive:

  • Priority service when you need it most
  • Discounted rates on repairs
  • Precision tune-ups for efficiency
  • Comprehensive safety checks for peace of mind

The best part? The value of these benefits is greater than the cost of a one-time tune-up and safety check.

Why Choose a Maintenance Plan?

Investing in a plan pays for itself:

  • Discounts + energy savings often outweigh the cost
  • Early detection of problems helps avoid costly repairs
  • Extended equipment lifespan with regular care
  • Confidence knowing your system is safe and ready year-round
