The summer is coming to a close and it's time for a seasonal HVAC maintenance check. It won't be long before you'll need to switch to heating in the evenings. Even though it may be a while before the serious cold weather comes upon us, you don't want to be among the many who find out that they have a problem with their system at the same time. There are only a fixed number of service technicians to go around, so some customers may have to wait. You can also learn more about HAVC maintenance via https://www.homemechanics.com/haverhill/.

It's not unusual for failures to occur when a system is turned on after a long period of inactivity. Your heating system has been dormant for quite a few months and you should have it checked out before the heating season is upon us. If you have gas heat, a technician can check for leaks in the heat exchanger, and also test and adjust to ensure that carbon monoxide (CO) is not being produced.
If you have a heat pump, a technician should check that the reversing valve is functioning properly to switch back and forth between the heating and cooling cycles. He or she should also verify that the auxiliary heater is in good condition and that the emergency mode for heating will work if needed.
This would also be a good time to clean the indoor and outdoor coils, and check for any problems that may have developed in the cooling system after a long hot season of operation. If you have a service or preventive maintenance contract, your technician will probably check all of the electrical connections while he's there. Otherwise you'll need to ask the technician specifically to do so.
A regular program of seasonal visits for HVAC maintenance service checks can go a long way toward keeping your system operating safely and efficiently.
