When your furnace becomes unreliable, inefficient, or too expensive to repair, replacing it can restore dependable heating and improve your home’s comfort. DorMar provides professional furnace installation and replacement throughout Central Ohio.

Since 1962, our team has helped homeowners select heating equipment suited to their homes, comfort preferences, and budgets. We evaluate your existing system, explain your replacement options, and properly size the new furnace before installation.

Our technicians complete the installation, test the system, and show you how to operate your new equipment. You receive clear recommendations and a furnace selected for the heating demands of your Central Ohio home.

When Should You Replace Your Furnace?

Furnace age alone does not determine whether replacement is necessary. The system’s condition, repair history, efficiency, safety, and ability to heat your home should all be considered.

Signs it may be time for furnace replacement include:

Frequent repairs: Repeated service calls can make continued repairs less practical, especially when several major components are wearing out.
Rising heating costs: Higher energy use may indicate declining performance, restricted airflow, or an aging furnace that is working harder to maintain the temperature.
Uneven heating: Persistent cold rooms and temperature differences may mean the furnace can no longer distribute heat effectively.
Unusual noises: Banging, grinding, rattling, or repeated startup noises may indicate worn mechanical components.
Short cycling: A furnace that repeatedly starts and stops may be improperly sized, overheating, or experiencing a control or airflow problem.
Safety concerns: A damaged heat exchanger, combustion problem, or recurring carbon monoxide concern may make replacement the safest recommendation.

Some symptoms can still be resolved with professional furnace repair. A technician should inspect the system before you decide whether repair or replacement offers better long-term value.

If a carbon monoxide alarm sounds, leave the home immediately and contact emergency services or your gas utility from a safe location.

Choosing the Right Replacement Furnace

The right furnace must be properly sized for your home and compatible with its ductwork, electrical system, fuel source, and thermostat. Installing a furnace based only on the size of the previous equipment can lead to short cycling, uneven temperatures, unnecessary energy use, and premature wear.

Factors to consider when selecting a furnace:

Fuel source: Gas and electric furnaces have different installation requirements, operating costs, and efficiency considerations.
System size: The furnace must have enough heating capacity for the home without being oversized. Square footage, insulation, windows, air leakage, and local weather conditions all affect sizing.
AFUE rating: Annual Fuel Utilization Efficiency, or AFUE, estimates how efficiently a furnace converts fuel into usable heat. A technician can explain how different efficiency levels may affect installation and operating costs.
Heating stages: Single-stage, two-stage, and modulating furnaces provide different levels of temperature control and energy use.
Blower operation: Multi-speed and variable-speed blowers can provide more consistent airflow and quieter operation than basic single-speed equipment.
Equipment compatibility: The new furnace must work correctly with your thermostat, ductwork, air conditioner, indoor air quality equipment, and venting system.

A furnace is not the only option available. Some homes may also be suitable for heat pump installation options that provide both heating and cooling. We can compare the available systems and help you determine which approach fits your home.

Furnace Replacement and Installation in Central Ohio

What to Expect During Furnace Installation

A successful furnace installation begins before the old equipment is removed. DorMar evaluates your home, existing system, and heating needs so the replacement equipment can be selected and installed correctly.

The furnace replacement process may include:

In-home assessment: We review the existing furnace, ductwork, thermostat, venting, fuel connections, electrical requirements, and comfort concerns.
Equipment recommendations: We explain appropriate furnace sizes, efficiency ratings, features, and available equipment options.
Removal of old equipment: The existing furnace is disconnected and removed so the installation area can be prepared.
Professional installation: The new furnace is connected to the ductwork, fuel or electrical supply, thermostat, venting, and other compatible HVAC components.
System testing: We check startup, airflow, thermostat communication, temperature rise, safety controls, and overall operation.
Customer walkthrough: Before leaving, we explain the system’s controls, filter requirements, basic maintenance, and warranty information.

How Much Does Furnace Replacement Cost?

Furnace replacement costs vary because every home and installation is different. The final price may be affected by the furnace size, efficiency rating, fuel source, equipment features, installation access, venting, ductwork modifications, electrical work, permits, and removal of the old equipment.

After evaluating your home, DorMar will provide a written estimate based on the equipment and installation work required. Homeowners can also review our available financing options for qualifying projects.

Furnace Replacement FAQs

How long does a furnace usually last?

Furnace lifespan varies based on the equipment, installation quality, usage, and service history. Regular annual furnace maintenance service can help identify developing problems and keep the system operating properly. Age should be considered alongside repair frequency, safety, efficiency, and overall performance.

Should I repair or replace my furnace?

Repair may be appropriate when the furnace is in good overall condition and the problem involves a replaceable component. Replacement may offer better long-term value when the system requires frequent repairs, has safety concerns, performs poorly, or is nearing the end of its service life. A technician can evaluate the system and explain your furnace repair options before you decide.
