What Our Residential Furnace Repair Services Cover


When it comes to furnace repair, Dilling is the best in the business. With decades of experience and a team of highly trained and knowledgeable technicians, you can trust that your furnace repair needs will be met efficiently and effectively.



Our team uses advanced techniques and state-of-the-art technologies to ensure all repairs are of the highest quality and that your equipment runs safely and reliably for years to come. Below is an in-depth look at some of the many solutions we deliver for electric, oil, and gas furnaces.

  • Furnace Filters

    With the winter months ahead, it is important to have a heating system that remains up and running. Keeping the furnace filter clean is a crucial part of this. Our expert technicians can clean and repair your existing filters, extending their lifespan and saving you money. 


    Additionally, we offer long-lasting replacement filters designed to reduce energy costs and keep air fresh and clean. With customizable options, these filters fit all types of furnaces, offer reliable performance due to their durable construction, and help capture dust and other contaminants from entering the home.

  • Heat Exchanger

    Heat exchangers are a critical component of furnaces, responsible for transferring heat from the combustion process to the air being circulated through the home. When a heat exchanger fails, it can pose serious safety risks and require immediate attention. Repairing a heat exchanger typically involves closely inspecting it for cracks, corrosion, or other damage, then either replacing the full heat exchanger assembly or welding/sealing any identified issues. This work should only be performed by a licensed HVAC technician, as improper repairs can lead to hazardous gas leaks.

  • Blower Motor

    The job of the blower motor in your furnace is to circulate the warm air throughout your home. So if it malfunctions, it can lead to a load of discomfort. Some symptoms of a broken blower motor are unusual noises, lack of airflow, and intermittent operation. Our HVAC techs can pinpoint these hiccups and more and formulate the most practical plan for resolution. Worn out belt? Electrical issues? Whatever the underlying problem is, we implement remedies that last so you can continue to enjoy consistent comfort.

  • Flame Sensor

    Designed to detect whether a flame is present when the gas valve opens, the flame sensor is another vital part of any hard-working furnace. If the sensor doesn’t detect a flame, it automatically signals the furnace to shut off the gas supply, preventing unburned gas from accumulating — a key safety feature. After years of heavy use, flame sensors can accumulate dirt or experience corrosion, leading to false readings or causing the furnace to shut off unnecessarily.


    When we repair a flame sensor, our process starts with a thorough inspection to pinpoint any buildup, corrosion, or electrical issues. We then clean or replace the sensor as necessary so it accurately detects the flame. This careful repair process restores reliable heating but also supports the safe, efficient operation of your furnace.

  • Gas Valve

    Gas valves control the flow of fuel to the furnace’s burners, a critical element for safety and performance. Once a gas valve fails, it may prevent the furnace from igniting or cause it to shut down unexpectedly, disrupting the consistent warmth you depend on. Our repair process begins with a precise diagnosis to identify issues such as clogs, faulty wiring, or mechanical malfunctions within the valve. Depending on the problem, we may clean the valve, adjust connections, or replace specific components to restore its functionality.

During an annual tune-up, our highly qualified technicians make certain that all the components of your heating system are in peak condition, including the pilot light, filter, circuit breaker, gas supply, and blower motor. This helps reduce accidents caused by furnace malfunctions, meaning a safer home for you and your family.

When Furnace Replacement May Be the Best Solution

Just like all heating systems, furnaces don’t last forever, even with regular maintenance and expert repair. If your furnace frequently breaks down, delivers uneven heating, or is simply nearing the end of its lifespan, replacement may be the smarter investment.


With reliable service, a typical furnace can last between 15-20 years. As they age, however, they can lose their energy efficiency and ability to perform at the same level, leading to higher utility bills and more frequent repairs. Upgrading to a new furnace equipped with modern efficiency features can be a game changer in dependability and savings.


Dilling believes in providing the best long-term solutions for our customers. We’ll carry out high-quality repairs with every job, but depending on the situation, we will also let you know if we think a replacement would be a more practical way to go. And since we can take on all your heating needs, we can carry out the furnace installation with ease, helping you select a new model and integrating it seamlessly into your space.
