How to Prepare Your HVAC System for Winter in Kensington, Connecticut

1. Replace or Clean Your Air Filters

A clogged filter makes your system work harder, drives up energy costs, and can shorten the life of the unit. This is the simplest fix on this list and the one most homeowners forget. If you can't remember the last time you changed it, that's usually a sign it's overdue.

2. Have Your System Professionally Inspected

An annual inspection catches small issues, worn belts, low refrigerant, minor electrical faults, before they turn into a system failure during the coldest week of the year. Fall, before demand spikes, is the easiest time to get on a technician's schedule. Call MS Contracting & Electric today to set up an inspection.

3. Check Your Thermostat Settings and Batteries

If you have a programmable or smart thermostat, this is a good time to review your schedule and confirm it's working correctly. For older thermostats, check the batteries so you're not caught off guard by a dead display in the middle of the winter.

4. Inspect Ductwork for Leaks or Damage

Leaky or disconnected ducts, especially in an attic or crawlspace, can lose a significant amount of heated air before it ever reaches your living space. If certain rooms always seem colder than others, ductwork is often the culprit.

5. Clear Space Around Outdoor and Indoor Units

Outdoor units, if you have a heat pump system, need clear space around them for proper airflow. Indoor units and vents should be free of furniture, curtains, or storage that can block airflow once the system is running more consistently.

6. Check Your Electrical Panel's Capacity

Heating systems, along with the space heaters and holiday lighting that often come with winter, put real strain on a home's electrical panel. If your panel is older or has a history of tripped breakers, it's worth having it evaluated before you're relying on it heavily every day. Our electrical services page covers what a panel evaluation typically involves.

7. Test Backup Heat Sources Before You Need Them

If you rely on a generator, space heaters, or a backup furnace during outages, don't wait for the first storm to find out something isn't working. Testing these now, while the stakes are low, is far better than troubleshooting during an actual outage.

FAQs

When should I have my HVAC system serviced before winter? 

Early to mid fall is ideal, before the coldest weather arrives and before technicians get booked up with emergency calls.

How often should I change my HVAC filter? 

Most systems need a filter change every 1 to 3 months, though homes with pets or allergies may need it more frequently, especially during peak heating season.

Why does my electrical panel matter for winter heating? 

Furnaces, heat pumps, space heaters, and holiday lighting all add load to your electrical system. An older or undersized panel is more likely to trip breakers or struggle under that combined demand.

What are signs my HVAC system needs repair before winter? 

Uneven heating, strange noises, higher than usual energy bills, or a system that runs constantly without reaching the set temperature are all signs worth having checked before winter arrives.

Should I cover my outdoor heat pump unit in winter? 

Generally, no. Most heat pumps are built to handle snow and cold, and covering the unit can actually trap moisture and cause more harm than good. Clearing snow and debris around it is usually enough.
