My heating and air conditioning systems are working just fine. Why should I invest in an annual maintenance?

You may think your system is running “just fine” and therefore, doesn’t need maintenance “this year”. However, skipping maintenances will accelerate costly repairs. Of course, with time, your air conditioner and heater’s performance will naturally decline. But, you can prolong the life of your systems and keep them running at peak, trouble-free efficiency longer, by enrolling in a maintenance program offered by a reputable HVAC service company.

We all know that New England weather can be fierce and unpredictable. For peace of mind, it may be well worth spending a couple hundred dollars each year on maintenance then to suddenly lose your heat during a major snow storm or air conditioning when it is blazing hot outside.

Professional service technicians, who understand your equipment, can thoroughly clean your systems, perform important safety checks and inspect your equipment for (and correct) potential problems before they become major expenses.

When hiring a service company to help you maintain your systems, consider companies that also offer parts and labor discounts on repairs, priority scheduling and never charge higher fees for after-hours services.

Here’s what you should expect from your HVAC service company:
