Cooler mornings and football signal fall in North Texas, but the heat lingers well into October. During this in-between season, air conditioners keep churning, furnaces wait in the wings and water heaters run nonstop—making it easy for maintenance to slip through the cracks until something breaks.
To help homeowners navigate the transition, experts at Sirius Plumbing & Air Conditioning share tips to keep home systems running smoothly, efficiently and safely all season.
What should homeowners check as summer winds down?
Transitioning your home for fall comes down to taking stock of the systems keeping you comfortable. Before winter arrives, Sirius recommends taking a close look at four essential components:
Everyday HVAC performance
Furnace readiness and safety
Water heater efficiency
Age and condition of home systems
Taking these steps helps homeowners address maintenance needs now and plan ahead for larger repairs or replacements on their own timeline.
What HVAC maintenance is needed after summer?
After months of running through Texas heat, an HVAC system deserves a reset. That starts with a few small maintenance steps that help the system run smoothly.
The simplest place to start is the air filter.
“Dirty filters are a common cause of service calls because restricted airflow can strain equipment, which can ultimately lead to bigger repairs,” said Brent Garrett, co-owner—with his wife Jeni Garrett—of Sirius Plumbing & Air Conditioning. “Basic 1-inch throwaway filters need changing every one to two months, while 4-inch pleated filters can last two to three months.”
Homeowners can also give the outdoor condenser a quick cleanup. Clearing away grass, dirt and summer debris around the unit helps maintain proper airflow.
Fall is also a good time to revisit thermostat settings. A 5-2 programmable thermostat lets homeowners set one schedule for weekdays and another for weekends. Raising the temperature a few degrees while the house is empty can reduce system workload and utility use.
How should homeowners prepare their furnace for fall?
A furnace that has been sitting unused for months should be checked before it is suddenly needed on a cold night. For homes with gas furnaces, that preparation is especially important because proper operation is also a safety issue.
Before the first cold front, homeowners can briefly turn on the heat to ensure the system runs normally. Pay attention to unusual noises, odors or inconsistent heating, which can signal that professional attention is needed.
Garrett also recommends scheduling a tune-up with Sirius Plumbing & Air Conditioning to ensure the furnace is operating safely and ready for cooler weather.
How can homeowners improve water heater efficiency?
While HVAC gets a lot of attention during seasonal changes, the water heater works year-round. Fall is a good time to check whether it is still performing efficiently.
Start by looking for signs of trouble, including leaks, unusual noises, inconsistent water temperatures or running out of hot water faster than usual. If an older unit shows its age, planning a replacement ahead of a breakdown can help homeowners avoid an unexpected loss of hot water.
It is also worth considering whether the current system still fits the household. A growing family or increased hot water demand could make a different system a better fit. Sirius can help homeowners compare water heaters based on household needs, budget and expected usage.
When should homeowners repair or replace aging systems?
Not every aging system needs replacement, but homeowners should know when repairs are no longer practical.
“Start to budget for a replacement once an HVAC system is outside its warranty period, which is typically 10 years when equipment is properly registered,” Garrett said. “As systems approach 12 to 15 years old, more components may begin reaching the end of their useful life.”
Frequent repairs, declining performance and rising utility costs can signal it may be time to invest in a newer, more efficient model. Timing can also work in a homeowner's favor: The cooler “shoulder months” can offer opportunities for discounts, rebates and financing options.
Sirius currently offers $1,500 off a new HVAC system, along with $500 off retail for tank water heaters and $750 off retail for tankless water heaters.
