Why is Planned Service the right choice for my business?

Lower Long Term Cost of Ownership: Benjamin Franklin said it best, "An ounce of prevention is worth a pound of cure." By investing in a yearly maintenance plan from Paitson Bros. you extend the useful life of your company's heating and cooling equipment, avoiding costly repairs and replacements. Systems that receive annual maintenance last, on average, 20% longer than systems that receive no annual maintenance.

Better Performance At Lower Operating Costs: Paitson Bros. planned service is designed to help your systems reach peak operating efficiency while reducing operating costs. By fine tuning the operating pressures and motor settings, cleaning the blower compartments and coils, and thoroughly checking the electrical systems, Paitson Bros. can give your system back its "like new" feel.

Dedicated Staff of Professionals: From a personal account manager, who meets with you to review system performance, to a dedicated staff of office personnel, to industry leading NATE and factory certified technicians - no other HVAC company can offer you the top-to-bottom service that you, your equipment, and your business demand.
