As summer winds down and cooler weather starts moving in, your HVAC system is about to make an important transition. After months of keeping your home cool, it will soon be responsible for keeping you comfortable through chilly fall days and, eventually, winter.
A little HVAC preventive maintenance in Sacramento and surrounding areas now can help improve efficiency, reduce the risk of unexpected breakdowns, and make sure your heating system is ready when temperatures drop. Here are several simple ways to prepare your HVAC system for fall.
Replace or Clean Your Air Filter
One of the easiest and most important HVAC maintenance tasks is changing your air filter.
During the summer, your cooling system may run for hours each day, allowing dust, pet hair, pollen, and other particles to collect in the filter. A dirty filter restricts airflow and forces your HVAC system to work harder to maintain a comfortable temperature.
Check your filter before the heating season begins and replace it if it looks dirty. Depending on your household, filter type, pets, and indoor air quality needs, filters may need to be replaced every one to three months.
Starting the season with a clean filter can improve airflow and help your system operate more efficiently.
Test Your Heating System Before You Need It
Don’t wait until the first freezing night to discover that your furnace or heat pump isn’t working properly.
Turn your thermostat to heating mode and raise the temperature a few degrees above the current indoor temperature. Your heating system should start within a few minutes and begin producing warm air.
Pay attention to unusual noises, odors, or performance problems. A slight dusty smell can sometimes occur when a heating system is turned on for the first time after sitting unused, but persistent burning odors, loud noises, or unusual cycling should be inspected by a qualified HVAC technician.
Testing your system early gives you time to address problems before cold weather arrives.
Check Your Thermostat
Your thermostat plays a major role in both comfort and energy use.
Make sure it is responding correctly and that your heating schedule still matches your family’s routine. Fall is also a good time to adjust programmable or smart thermostat settings as your schedule and outdoor temperatures change.
For example, lowering your thermostat when you’re asleep or away from home may help reduce unnecessary heating costs.
If you’re still using an older manual thermostat, you may also want to consider upgrading to a programmable or smart model for greater control over your home’s temperature.
Clear Your Vents and Registers
Walk through your home and check all supply vents and return-air registers.
Furniture, rugs, curtains, toys, and other household items can accidentally block airflow. Keeping vents open and unobstructed helps your HVAC system distribute heated air more effectively.
You can also use a vacuum to remove visible dust and debris from the outside of registers.
Avoid closing large numbers of vents in unused rooms unless your HVAC system was specifically designed for that type of zoning. Restricting too much airflow can sometimes create performance issues.
Inspect the Outdoor Unit
If your home uses a heat pump or central air conditioning system, take a look at the outdoor equipment.
Leaves, grass clippings, weeds, branches, and other debris can accumulate around the unit during the summer and fall. Remove loose debris and maintain adequate clearance around the equipment so air can circulate freely.
As leaves begin falling, check the area periodically to make sure the unit doesn’t become covered.
Avoid opening or disassembling HVAC equipment yourself. Internal inspections, electrical repairs, and refrigerant-related work should be handled by a trained professional.
Check Your Carbon Monoxide Detectors
Homes with fuel-burning furnaces, boilers, fireplaces, or other combustion appliances should have functioning carbon monoxide detectors.
Fall is a good time to test each detector and replace batteries if necessary. You should also check the manufacturer’s recommendations for replacing the detector itself, since carbon monoxide sensors do not last forever.
Carbon monoxide is odorless and colorless, so a working detector is an important part of home safety.
Schedule Professional HVAC Maintenance
Even if your heating system appears to be working properly, an annual professional inspection can help identify developing problems before they turn into larger repairs.
During a typical heating maintenance visit, an HVAC technician may inspect electrical components, test system operation, check safety controls, examine the blower assembly, inspect heat-exchange components where applicable, and verify that the system is operating properly.
Routine maintenance can also help your equipment operate more efficiently and may extend the useful life of the system.
Scheduling service during early fall can be especially helpful because HVAC companies often become much busier once the first major cold spell arrives.
Look for Signs Your System Needs Attention
As you begin using your heating system, watch for changes in performance.
Possible warning signs include rooms that heat unevenly, unusually high energy bills, frequent cycling, weak airflow, strange noises, persistent odors, or difficulty maintaining the temperature set on the thermostat.
These symptoms don’t always mean that a major repair is needed, but they are worth investigating before winter puts additional strain on the system.
Get Ready Before the Cold Arrives
Preparing your HVAC system for fall doesn’t have to be complicated. Changing the filter, testing the heat, clearing vents, checking safety equipment, and scheduling preventive maintenance can go a long way toward keeping your home comfortable throughout the colder months.
Taking care of these tasks before temperatures drop can also give you peace of mind knowing your heating system is ready when you need it most.
A little preparation today can help prevent an inconvenient—and potentially expensive—HVAC problem later in the season.
