Thermostat Malfunctions


Inaccurate temperature readings or a malfunctioning thermostat.

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.

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.

4 Warning Signs That It’s Time For A Furnace Repair

Prompt repair and maintenance of your furnace is essential not only for comfort but also to ensure the safety and longevity of your heating system. As the colder months approach, it’s necessary to pay attention to any warning signs that may indicate it’s time for a furnace repair. Ignoring these signs might lead to more significant issues down the line, resulting in costly repairs or even replacement of your furnace.

Secure your winter comfort by reaching out to Poston Brothers Heating and Cooling at the first indication of furnace issues; don’t leave it to chance.
Here, we’ll delve into four unmistakable signals that it’s time to call in the experts.

Unusual Noises

One of the earliest indicators that your furnace may be experiencing issues is the presence of strange and unfamiliar noises. While a gentle hum is perfectly normal, loud banging, screeching, or rattling sounds should not be ignored. These noises may point to a variety of problems, such as loose components, a malfunctioning blower motor, or even a cracked heat exchanger. Ignoring these auditory warnings could lead to more severe damage and, ultimately, a complete system failure.

If you hear any unusual sounds emanating from your furnace, it’s time to reach out to Poston Brothers Heating and Cooling for a thorough inspection and prompt repairs.

Inconsistent Heating

Are you noticing uneven heating throughout your home? If some rooms feel warmer than others or if you’re constantly adjusting the thermostat to maintain a comfortable temperature, it’s a clear sign that your furnace is struggling. Inconsistent heating could be the result of a faulty thermostat, a malfunctioning blower, or even a clogged air filter hindering proper airflow.

Ignoring this warning sign not only compromises your comfort but also forces your furnace to work harder, potentially increasing energy consumption and utility bills. We can diagnose the issue and implement the necessary repairs to restore your furnace’s efficiency and even heating distribution.

Increased Energy Bills

A sudden spike in your energy bills without a corresponding increase in usage is a red flag that your furnace may be operating inefficiently. As furnaces age or undergo wear and tear, they become less efficient, requiring more energy to produce the same level of warmth. This inefficiency impacts your wallet and also contributes to unnecessary strain on your furnace.

We recommend keeping a close eye on your energy bills. If you notice an unexplained increase, it’s time to schedule a furnace inspection. Our experienced technicians at Poston Brothers Heating and Cooling can identify and address the issues causing energy inefficiency, ultimately saving you money in the long run.

Visible Signs of Wear and Tear

A visual inspection of your furnace can provide valuable insights into its overall health. Signs of corrosion, rust, or cracks in the system are clear indicators that your furnace is in distress. Additionally, if you notice an excessive amount of soot around the furnace, it may be a sign of incomplete combustion, which can pose safety hazards.

We emphasize the importance of regular visual checks to catch these warning signs early on. Our skilled technicians at Poston Brothers Heating and Cooling can conduct a comprehensive assessment, identifying and resolving any visible issues to ensure your furnace operates safely and efficiently.

If you’ve noticed any of these warning signs, don’t hesitate to contact us. Our team of experts is dedicated to ensuring your furnace operates at its best, providing reliable warmth and comfort throughout the winter season. Act promptly, and let us keep your home cozy and your furnace running efficiently.
