Essential Furnace Maintenance for Dover Homes

When winter temperatures in Dover, NH drop below freezing, your furnace becomes the heart of your home’s comfort system. At Paul the Plumber, we understand that regular furnace maintenance isn’t just about preventing breakdowns—it’s about ensuring your family stays warm, safe, and comfortable throughout the harsh New England winters. Our family owned and operated business has been serving the Dover community for 22 years, and we’ve seen firsthand how proper maintenance can extend furnace life by 5-10 years while reducing heating costs by up to 30%.

Your furnace works tirelessly during the heating season, cycling on and off dozens of times per day to maintain your desired temperature. This constant operation puts significant stress on components like heat exchangers, blower motors, and ignition systems. Without regular maintenance, dust accumulation, worn parts, and efficiency losses can lead to unexpected failures during the coldest nights of the year. We treat customers like family, which is why we emphasize preventive care to avoid emergency situations that leave you without heat.

Comprehensive Inspection Process

Our licensed technicians follow a detailed 21-point inspection process that examines every critical component of your furnace system. We begin by checking the heat exchanger for cracks or corrosion, as this vital component separates combustion gases from the air circulating through your home. Even microscopic cracks can allow carbon monoxide to enter your living spaces, making this inspection crucial for your family’s safety. Our technicians use specialized cameras and testing equipment to detect issues that might be invisible to the naked eye.

The inspection continues with a thorough examination of your furnace’s electrical components, including control boards, safety switches, and wiring connections. Loose connections can cause intermittent operation or complete system failure, while worn contactors may prevent your furnace from starting reliably. We measure amp draws on all motors to identify potential failures before they occur, and we test all safety devices to ensure they’ll protect your system and home if problems arise. As a BBB accredited business with an A+ rating, we provide detailed inspection reports that explain our findings in clear, understandable terms.

Critical Cleaning and Adjustments

Dust and debris accumulation represents one of the most common causes of furnace problems in Dover homes. During our maintenance visits, we thoroughly clean the burner assembly, removing carbon deposits that can cause uneven heating and increased fuel consumption. The flame sensor, a small but critical component, receives special attention as even a thin layer of oxidation can prevent your furnace from staying lit. We also clean and inspect the blower assembly, ensuring proper airflow throughout your ductwork system.

Gas pressure adjustments require precise calibration to ensure optimal combustion efficiency. Our technicians use digital manometers to measure and adjust gas pressure to manufacturer specifications, optimizing the fuel-to-air ratio for maximum efficiency and minimum emissions. We also check and adjust the furnace’s temperature rise, ensuring it operates within design parameters. This prevents overheating that can damage the heat exchanger while maintaining comfortable air temperatures at your registers. With thousands of verified 5-star reviews across multiple review platforms, our attention to detail sets us apart.

Filter Management and Indoor Air Quality

Your furnace filter plays a crucial role in both system efficiency and indoor air quality. During Dover’s winter months, when homes remain sealed against the cold, indoor air can become two to five times more polluted than outdoor air. We educate homeowners about proper filter selection, explaining how MERV ratings affect both filtration efficiency and system airflow. Higher-rated filters capture smaller particles but can restrict airflow if your system wasn’t designed for them, potentially causing premature component failure.

We recommend filter replacement schedules based on your specific circumstances, including pet ownership, allergies, and home occupancy. Standard one-inch filters typically require monthly replacement during heating season, while high-capacity pleated filters may last three to six months. We can also install advanced filtration systems, including electronic air cleaners and UV germicidal lights, to address specific air quality concerns. Our technicians explain how these systems work with your furnace to create a healthier home environment.

Safety Testing and Carbon Monoxide Prevention

Carbon monoxide poisoning sends over 50,000 Americans to emergency rooms annually, making combustion safety testing an essential part of furnace maintenance. We perform comprehensive CO testing throughout your home, checking ambient levels and measuring CO production at the furnace. Our technicians inspect the venting system for proper draft, blockages, and deterioration that could allow dangerous gases to enter your living spaces. We also verify that your carbon monoxide detectors function properly and are positioned correctly for maximum protection.

The combustion analysis includes checking the furnace’s oxygen and carbon dioxide levels to ensure complete fuel combustion. Incomplete combustion not only wastes fuel but produces dangerous carbon monoxide. We inspect the condition of flue pipes, checking for rust, gaps, or improper pitch that could allow condensation to accumulate and cause corrosion. All of our technicians are licensed and background checked, providing peace of mind when we’re working in your home to ensure your family’s safety.

Energy Efficiency Optimization

Dover residents typically spend $1,200 to $2,000 annually on heating costs, making efficiency improvements valuable investments. During maintenance visits, we analyze your furnace’s actual efficiency compared to its rated capacity, identifying factors that may be increasing your energy bills. Simple adjustments like calibrating the thermostat, sealing duct connections, and optimizing fan speeds can reduce heating costs by 10-15% without any equipment replacement.

We also evaluate your home’s overall heating system design, looking for issues like undersized returns, poorly placed registers, or inadequate insulation that force your furnace to work harder than necessary. Our up front pricing means you’ll know exactly what any recommended improvements will cost before we begin work. We back all of our work with a 2 year parts and labor warranty, and club members receive an extended 3 year parts and labor warranty for additional peace of mind.
