Furnace Services

Most homes in our area run on gas, but we also service oil-fired furnaces, something not every HVAC company around here does. In more rural parts of the Great Lakes Bay Region, oil heat is still common, and we’re familiar with both older models and newer high-efficiency oil systems. If your furnace is having trouble keeping up, turning on and off a lot, or making strange sounds, we’ll take a closer look and explain what we find. Whether it’s a simple repair or time for a replacement, we’ll help you figure out the right move. We emphasize transparent communication, ensuring you understand the condition of your system and the options available. Trust us to provide honest recommendations focused on both your comfort and your peace of mind. By partnering with us, you'll experience comprehensive service that ensures you're never left out in the cold.

We know how quickly the cold can set in here in Michigan, and how frustrating it is when your furnace isn’t working properly. Whether you're dealing with uneven heating, strange sounds, or a system that’s just not running as efficiently as it should, we’re here to help troubleshoot and get things back on track.

Our technicians are equipped with the latest tools and diagnostic techniques to swiftly identify and resolve issues, minimizing downtime and maximizing comfort. We understand the inconvenience a malfunctioning furnace can cause, and our goal is to restore warmth and normalcy to your home as efficiently as possible.

Furnace Installations & Replacements

When repairs no longer make sense, or you’re ready for a more efficient system, we’re here to help you through the upgrade. We install a range of furnace types, including Trane gas models, oil systems, and Mitsubishi Electric ductless units that are great for properties without central ductwork. Our expert installers handle each project with precision, ensuring optimal performance and longevity. We also take the time to explain the installation process, answer any questions you might have, and ensure you feel confident with your new system. By choosing Custom Engineering, you're investing in a long-term solution tailored to your specific needs.

The Importance of Proper Furnace Sizing

Choosing the right furnace size is critical for efficient home heating. An oversized furnace can lead to frequent cycling, while an undersized unit might struggle to maintain a comfortable temperature. Our team assesses your home’s unique needs, considering factors such as square footage, insulation quality, and window placement to recommend the most suitable model. This careful planning not only ensures optimal home comfort but also helps reduce energy wastage and prolongs the lifespan of your system.

Installing the correct furnace is more than just about comfort. It also involves compliance with energy-efficiency guidelines, which can lead to significant savings on utility bills. At Custom Engineering, we stay updated on Michigan's latest standards to ensure every installation meets local requirements and achieves the best possible efficiency for your home.

Not sure what’s right for your space? We’ll walk you through your options and provide a free estimate based on your home’s size, insulation, and heating needs. Financing options are available through Wells Fargo, including 0% plans for qualified customers.

Energy Efficiency & Cost Savings

Switching to a high-efficiency furnace can result in substantial energy savings, particularly during the harsh winter months in Bay City. An energy-efficient system not only lowers your carbon footprint but also reduces monthly utility bills, making it an environmentally and financially wise choice. We guide our customers in choosing models that align with the latest technological advancements and Energy Star certifications, ensuring maximum return on investment.

Moreover, we register your new system for any possible rebates and incentives available in Michigan. With our help, you can take advantage of state programs aimed at encouraging energy efficiency. These savings, combined with our competitive financing options, make upgrading your furnace an attainable goal for all homeowners.

Seasonal Furnace Maintenance

Regular furnace maintenance helps your system run more efficiently and can prevent unexpected issues during the coldest months here in Bay City and the Great Lakes Bay Region. With the temperatures dropping and lake winds picking up, having a furnace that’s ready for the season makes a big difference in your home’s comfort.

During a seasonal tune-up, we handle the important tasks that keep your furnace in top shape. We’ll clean the burners, inspect the blower components, check safety controls, and examine the electrical connections. For oil furnaces, we also clear out built-up soot and check the nozzle and filter, helping the system burn fuel more cleanly and efficiently.

Whether you're after a quick once-a-year check or prefer a more regular service plan, we offer flexible options that work around your schedule. If something doesn’t seem right during the tune-up, we’ll take the time to walk you through what we find and discuss the best next steps based on your furnace’s setup. Commitment to thoroughness and customer education distinguishes our maintenance services—we believe informed customers are empowered customers. Our goal is to foster a partnership that extends the life of your furnace and enhances its performance, season after season.

Comprehensive Safety Checks

Safety is paramount during furnace maintenance, especially given the risks associated with natural gas and oil systems. Our inspections include a careful review of venting systems to ensure they are functioning correctly and not posing carbon monoxide hazards. We also check for gas leaks and make sure that all safety controls are operational. These preventive measures contribute not only to the safety of your household but also to the peace of mind of ongoing reliable service.

In addition to safety checks, we recommend maintenance products designed to enhance the performance and longevity of your system, such as programmable thermostats and high-quality air filters. By keeping your furnace in prime condition, you ensure it operates with maximum efficiency while safeguarding the health and comfort of your home.

When to Call About Furnace Issues

You don’t always need to wait for a full breakdown to give us a call. If something seems off, it might be time to get your furnace checked out.

Common signs include:

Cold spots or uneven heating. Some rooms are warm, others feel like an icebox.
Strange sounds. Banging, rattling, or rumbling could mean loose parts or airflow issues.
Unusually high energy bills. If your usage hasn’t changed but your bill has, the system might be working harder than it should.
Short cycling. The furnace kicks on and off constantly without fully heating your home.
A yellow pilot light. This can point to combustion problems that may need attention.
No warm air at all. If you’re only getting cold air, something’s definitely off.

We’re available to troubleshoot these issues and offer same-day service when possible. Even if it’s after hours, you can call and talk to a real person from our team. Our 24/7 availability ensures you get timely assistance, no matter when problems arise. We prioritize your comfort and aim to resolve your furnace issues with urgency and expertise, providing you with reliable and trustworthy service that you can count on.

Recognizing problems early not only helps maintain your home comfort but can prevent more serious issues—and more expensive repairs—down the line. With our guidance, you can make informed decisions, opting for repair options that best suit your needs and budget.

Need to schedule a repair or talk through your options? Contact us today at (989) 474-2870 or online.

Frequently Asked Questions

How Often Should I Have My Furnace Serviced?

Regular maintenance of your furnace is key to its longevity and performance. We recommend that you have your furnace serviced at least once a year, preferably in the fall, before the heating season begins. This ensures your system is in top condition as temperatures drop, minimizing the risk of unexpected breakdowns during the winter when you need heat the most. An annual tune-up can help identify worn components and inefficiencies, potentially saving you money on future repairs and utility costs.

Why Is My Furnace Making Strange Noises?

Unusual noises such as banging, rattling, or squealing coming from your furnace can be indicative of several issues, including loose components, motor problems, or airflow constraints. It's important not to ignore these sounds, as they often signal the need for maintenance or repairs. Our technicians are adept at pinpointing the source of these noises and providing solutions that restore quiet and efficient function to your equipment.

What Are the Benefits of an Energy-Efficient Furnace?

Investing in an energy-efficient furnace can lead to significant benefits, both for the environment and your wallet. These models consume less energy, reducing your utility costs and lowering your carbon footprint. Additionally, they often come with advanced features like variable-speed blowers, which enhance comfort by maintaining consistent temperatures and improving air quality. Energy-efficient furnaces are designed to meet strict environmental standards, contributing to greener living while offering you impressive long-term savings.
