Thermostat Malfunctions


Inaccurate temperature readings or a malfunctioning thermostat.


Verify the thermostat settings, replace batteries, and ensure calibration accuracy. If problems continue, consider a professional thermostat replacement.

Dirty or Clogged Filters


Decreased airflow and efficiency due to dirty or clogged filters.


Frequently change or clean filters for optimal system performance. This routine maintenance greatly improves your system’s efficiency.

Ignition or Pilot Control Issues


Difficulty igniting the pilot light or burner.


Clean the ignition system, inspect the pilot light, and check for blockages. If issues persist, seek a professional inspection from Poston Brothers Heating and Cooling.

Lack of Maintenance


Neglecting regular maintenance leads to inefficiency and potential breakdowns.


Arrange yearly professional maintenance to keep your heating system running smoothly. Preventive care can prevent expensive repairs.

Frequent Cycling


The system frequently turns on and off.


Inspect for clogged filters, review thermostat settings, and ensure appropriate system sizing. For ongoing issues, consult a heating professional.

Uneven Heating


Some areas remain cold while others are overly warm.


Adjust ductwork dampers, check for blockages, and confirm open vents. Persistent problems might indicate ductwork issues needing professional attention.

Strange Noises


Uncommon sounds like banging, rattling, or whistling.


Locate and address the noise source. It could be due to loose parts, air in the system, or failing components. Seek professional help if necessary.

Leaky Ducts


Heated air loss through duct cracks or leaks.


Seal any duct leaks to enhance efficiency. Professional duct sealing can significantly improve your heating system’s performance.

Faulty Limit Switch


The limit switch doesn’t turn off the blower, causing constant cycling.


Refer to the manufacturer’s manual for resetting the limit switch. For ongoing problems, professional assistance is recommended for switch replacement.

System Age


Older systems may become less efficient and more likely to break down.


If your system is nearing its lifespan end, consider upgrading to a more energy-efficient model. New systems offer advanced features for improved performance and lower energy use.

7 Basic Tips For Fixing Your Heater Like A Pro

When your heater decides to take an unexpected vacation in the dead of winter, it can leave you caught in the cold. But worry not! This guide will walk you through 7 essential tips to help you troubleshoot and fix your heater like a pro. Brought to you by Poston Brothers Heating and Cooling, a trusted name in professional heating repair in Kentucky, these pointers are aimed at empowering you to handle minor heating issues without panic.

Whether you’re a homeowner looking to save on repair costs or a DIY enthusiast interested in heating service tips, this guide is your first step toward mastering the basics of heating repair. So, let’s dive in!

Check the Thermostat

The first step in troubleshooting your heater is often the simplest. Ensure that your thermostat is set to the desired temperature and mode (heat, not cooling, or fan-only). If you have a programmable thermostat, double-check the schedule and settings. Low batteries could also be a culprit, so replace them if necessary.

Inspect the Air Filters

Clogged or dirty air filters can impede airflow and strain your heating system. Regularly check and replace air filters every 1-3 months, depending on usage. Clean filters promote better air quality and improve the efficiency of your heating system, saving you money in the long run.

Examine the Pilot Light

If your heater uses a gas furnace, check the pilot light. A pilot light that’s out or has a weak flame might be the reason your heater isn’t working. Follow the manufacturer’s instructions to relight the pilot light, and if it continues to go out, there might be an underlying issue that requires professional attention.

Inspect the Circuit Breaker

A tripped circuit breaker can result in a lack of power to your heating system. Locate your electrical panel and check if the circuit breaker for your heater is in the “on” position. If it has tripped, reset it and monitor for any further issues. If the problem persists, it may be indicative of a more significant electrical problem that requires professional assistance.

Clear Vents and Registers

Ensure that all vents and registers in your home are unobstructed by furniture, drapes, or any other objects. Proper airflow is crucial for an efficiently functioning heating system. If the vents are blocked, it can lead to uneven heating and put unnecessary strain on your system.

Inspect the Ductwork

Leaky or damaged ductwork can lead to heat loss and reduced efficiency. Examine your ductwork for any visible issues, such as gaps, holes, or disconnected sections. Seal any leaks with duct tape or hire a professional for a more comprehensive inspection and repair.

Schedule Regular Maintenance

Prevention is critical to avoiding major heating issues. Consider scheduling annual maintenance with a professional heating and cooling service, like Poston Brothers Heating and Cooling. Regular maintenance can catch potential problems early, ensuring that your heater operates efficiently throughout the colder months.
