    My furnace suddenly died and Marx Mechanical staff rearranged their schedule to be here the next day to replace my furnace (in a snowstorm). All my questions were answered and they even helped me set up the Daikin app on my phone.

    "The team at Marx Mechanical did an amazing job with my install."

    They answered all of my questions, gave honest advice, and put in the extra effort to fit my new Daikin air handler into the very limited space that was available.

    "So pleased to have chosen Marx Mechanical!"

    From the initial phone call, to the visit to the showroom, to the install, to the subsequent follow up of such, all the staff (including owner) could not have been more accommodating and more knowledgeable.

Frequently Asked Questions

How Long Does Furnace Replacement Take?

A standard furnace replacement, involving the removal of the old unit and the installation of a new one, typically takes between four to eight hours. The total time depends on the complexity of the job, such as whether ductwork modifications or venting changes are necessary. If the existing flue, gas line, or electrical connections require significant changes to meet current codes, the replacement may take longer. In most residential cases, a professional team can complete the entire replacement within a single day. Your installer will provide a precise timeline after completing a pre-installation assessment of your home.

What Size Furnace Does My Home Need?

The correct size furnace is determined by performing a detailed calculation known as a Manual J load calculation. This process ensures the furnace is precisely sized by factoring in your home’s square footage, insulation quality, window efficiency, and local climate data. An oversized furnace will short-cycle, leading to energy waste, poor temperature control, and premature component wear. Conversely, an undersized unit will run constantly and struggle to keep your home warm during peak cold weather. Always rely on a professional HVAC contractor to accurately perform this complex sizing calculation.

How Long Do New Furnaces Typically Last?

A high-quality, newly installed furnace generally has a lifespan of 15 to 20 years if it is properly maintained. The unit's longevity depends heavily on the frequency and quality of professional maintenance it receives throughout its life. Furnaces that are serviced annually and have their filters changed regularly tend to operate efficiently for the full two decades. Extreme usage or neglecting minor repairs will significantly shorten the unit's lifespan. Investing in a quality brand and ensuring proper installation are also major factors in maximizing its durability.

Can I Install A New Furnace Myself?

No, you should not attempt to install a new furnace yourself under any circumstances. Furnace installation involves complex and highly dangerous tasks, including connecting gas lines, handling high-voltage electricity, and ensuring proper venting for deadly carbon monoxide. In Newmarket, all gas appliance installations require permits and mandatory inspections by certified safety authorities. Incorrect DIY installation can void warranties, lead to inefficient operation, and, most critically, create extreme fire and health hazards. Always hire a licensed, certified HVAC technician to handle the entire installation process.

How Can I Maintain My Newly Installed Furnace?

The most critical maintenance task for your new furnace is regularly changing the air filter every one to three months based on the filter type and household usage. You should also ensure the area around the furnace remains clean and unobstructed to allow for proper airflow and safe operation. If you have a high-efficiency furnace, check the condensate drain line occasionally to ensure it is not clogged. Most importantly, schedule annual professional maintenance every fall to have components cleaned, safety controls checked, and the unit tuned for optimal efficiency. Consistent maintenance preserves the warranty and maximizes the unit's performance. We offer comprehensive maintenance plans to ensure that your stay warm all year-round.
