You want your household heating system to provide enough warmth to raise the indoor temperature to a comfortable level. That’s just what a heating system is for!
But the amount of heat isn’t the whole story. Properly providing comfort to a home requires moving the heat around to the different rooms. If some rooms are getting too hot while others feel like freezers, it’s called uneven heating—and it’s not fun. Unfortunately, it’s a common trouble people encounter, and it often calls for professional HVAC services.
Below, we’re going to look into some of the reasons your house is experiencing uneven heating.
Busted zone controls
If your home has a zone control system installed to regulate which rooms receive heated air, uneven heating often indicates the controls have malfunctioned. For example, one of the dampers in the ducts may have become stuck open or closed. Or one of the local thermostats monitoring temperatures in the rooms may have broken so it isn’t signaling the central thermostat to send heat its way. A professional can look into the system to see what’s gone wrong.
The heater may be functioning fine, but the problem is that not all the heated air is reaching certain rooms because the air is getting out through leaks and breaks in the ductwork. This is a problem we frequently see, and up to 30% of the heated air moving through a ventilation system can escape because of these leaks. So not only are you receiving uneven heating, you’re paying extra to heat air that isn’t going into the house. Let our technicians handle the duct repairs services to correct this.
Clogged HVAC air filter
This is a basic trouble you can correct yourself—as well as prevent in the future. The air filter in your forced-air system (furnace, heat pump) collects dust and dirt over time. When it becomes fully clogged, it will throttle airflow into the system and into the ducts. Less airflow causes uneven heating, with the most distant rooms receiving the least amount of heat. Replace the filter with a clean one, and do this every 1 to 3 months to ensure the heater always has an uncongested filter.
Short-cycling heating system
Short-cycling is when a heating system shuts on and off faster than it can complete a heating cycle. There are many reasons why this may happen, but the result is the heater won’t run long enough to distribute warmth evenly throughout the house. If you notice the heater turning on and off repeatedly during an hour, call HVAC technicians right away. Short-cycling creates numerous troubles for a heater and needs to be fixed ASAP.
A dying heater
The Big One—your heating system may be losing its heating power in its old age. Heaters older than 15 years may begin to fail and produce a lower heat output. Uneven heating is an early indication this is occurring. Have HVAC experts analyze the system and advise you on whether repairs can keep it going or if it’s more cost-effective to replace it.
