Homeowners HVAC Maintenance Contracts


Get peace of mind and save money with a Wolverton Air maintenance contract for regularly scheduled service on your heating or air conditioning systems.

 Investing in a planned maintenance agreement for your home's comfort system is one of the best investments you'll ever make. Scheduled maintenance tune-ups can reduce the cost of heating and cooling your home, extend the life of your equipment and detect, as well as correct, operational issues before they happen. This is valuable, low-cost protection.

During your heating tune-up this fall, our expert technicians put your system through a comprehensive inspection. The result: a well-tuned heating system that will run at the peak of efficiency and lower the risk of needing emergency service. You'll have peace of mind that your heating system will be operating at peak performance, using less energy and saving you money. Preventive maintenance not only extends the life of your system, but protects against costly breakdowns — which could leave you with a chill.


When you call to schedule your home's system cleaning, take a moment to ask us about a Maintenance Agreement. This scheduled rotation of seasonal maintenance visits allows us to inspect and tune up your home air system to help ensure it runs smoothly. Plus, if your system ever requires a mid-season visit from one of our technicians, your Maintenance Agreement entitles you to priority service and discounts.

Benefits of your HVAC maintenance contract


  • 15% discount on all parts AND labor
  • Special discounted overtime rate,
  • Freon is sold at a reduced rate.
  • We offer multi-year maintenance contracts, maximum of 5 years.
  • A free 1" Standard Size filter for every system. High efficiency filters or special sized filters are priced at a special rate.
  • Two inspections. One to check your heating system. One to check your air conditioning.
  • Commercial customers are priced based on an individual basis.

Maintenance contracts are non-refundable. They may be transferable to a new address on a case-by-case basis depending on circumstances. For instance if a customer moves out of our service area we cannot transfer the contract to the new address. The contract is transferable to a new owner so long as Wolverton Co. Inc. is informed of the sale of the property and new customer information is given; otherwise the contract is void. The new owner can use the existing contract for the remainder of its duration. However once the expiration date on the contract passes it will then be necessary to purchase a new contract.
