Furnace Replacement Services

From custom sizing to seamless installation, Harts replaces aging furnaces with high-efficiency systems built for lasting home comfort.

High-Efficiency & Fuel Options

Compare gas, electric, and dual-fuel systems based on efficiency ratings, operating costs, and your home’s existing HVAC setup.

System Sizing & Selection

Choose a properly sized furnace based on your home’s square footage, heating demand, insulation, and layout.

New Furnace Installation

Airflow & Ductwork

Evaluate ductwork and airflow to support proper heat distribution and reliable furnace performance.

When Furnace Replacement Makes Sense

A furnace does not always need to be replaced just because it breaks down. Replacement may be worth considering when the system is older, needs frequent repairs, struggles to heat the home, or requires a major repair that is difficult to justify.

Harts can evaluate the system, explain what is failing, and help you compare another repair with the cost and long-term value of installing a new furnace.

Planning For Furnace Replacement Costs

The cost of a new furnace can vary based on the system type, efficiency level, installation requirements, and any updates needed for the existing HVAC setup. Understanding those factors upfront can make it easier to compare your options.

Harts provides clear estimates before installation and can explain available financing options that may help make a new heating system more manageable for your budget.

Signs Your Furnace May Need To Be Replaced

Some furnace problems can be repaired, but system age, recurring repairs, rising heating costs, and declining performance can make replacement worth considering.

Your Furnace Is 15+ Years Old

Many furnaces last around 15 to 20 years. As the system ages, components can wear down, efficiency may decline, and unexpected repairs can become more common.

Your Home Has Uneven Heating

Persistent cold rooms, weak airflow, or frequent thermostat adjustments may indicate that the furnace is struggling to heat the home consistently.

Repairs Are Becoming More Frequent

If your furnace requires service year after year, those recurring repair bills can quickly add up to a significant portion of what you’d invest in a new, reliable system.

A Major Repair Is Needed

When an expensive component fails, it may be worth comparing the repair cost, furnace age, and overall condition with the cost of replacement.

Heating Bills Keep Increasing

Higher heating costs can indicate that an aging furnace is losing efficiency or working harder than it once did to maintain the temperature in your home.

You Notice Noises Or Short Cycling

Rattling, squealing, banging, or frequent on-and-off cycling can signal mechanical strain, component problems, or airflow issues that may point to a declining system.

Furnace Replacement Guide

What To Consider When Replacing A Furnace

Replacing a furnace involves more than choosing a brand or efficiency rating. Heating capacity, fuel type, airflow, system controls, and your existing HVAC setup can all affect how the new furnace performs.

Choosing Your New Furnace

The right furnace depends on how your home uses heat, the equipment already installed, and the features you want from your new system.

AFUE efficiency ratings

Annual Fuel Utilization Efficiency (AFUE) measures how efficiently a fuel-burning furnace converts energy into heat. Higher-efficiency options can reduce wasted energy compared with older equipment.

Fuel and system type

Depending on the existing HVAC system and available utilities, options may include gas furnaces, electric furnaces, or dual-fuel systems that combine a furnace with a heat pump.

Heating capacity and stages

Proper BTU sizing helps the furnace meet the home’s heating demand without excessive cycling. Depending on the equipment, options may include single-stage, two-stage, or variable-capacity operation.

Planning For The Installation

A new furnace also needs to work properly with the equipment and infrastructure already serving the home.

Ductwork and airflow

Supply and return ductwork should provide enough airflow for the new furnace. Airflow restrictions or improper static pressure can affect heating performance and equipment operation.

Venting and connections

Installation requirements can vary depending on the furnace type and efficiency level. Venting, fuel connections, electrical components, and condensate drainage may need to be reviewed during replacement.

Thermostat and controls

Some newer furnaces use staged or variable operation that may require a compatible thermostat or control system. Checking compatibility helps ensure the equipment can use its intended features.

Furnace Replacement FAQs

Quick answers to common questions about furnace replacement, installation, costs, and choosing a new system.

Many furnaces last around 15 to 20 years, although lifespan varies based on equipment, usage, maintenance, and installation. As a furnace gets older, repairs and efficiency concerns may become more common.

That depends on the furnace’s age, repair history, overall condition, and the cost of the current repair. If an older furnace needs frequent service or a major repair, comparing the cost of repair with replacement can help you make a more informed decision.

Many straightforward furnace replacements can be completed within a day, but the exact timeline depends on the existing system and installation requirements. Venting, electrical work, ductwork, or other modifications can add time. During the estimate and system evaluation, a Harts technician can provide a more accurate timeline based on your home and replacement needs.

Furnace replacement cost depends on the equipment type, efficiency rating, heating capacity, and installation requirements. Harts provides upfront pricing so you can review the cost before approved installation work begins.

The right furnace size depends on your home’s heating demand rather than simply matching the old equipment. Factors such as square footage, layout, insulation, windows, and existing HVAC setup can influence the heating capacity your home needs. During your estimate and system evaluation, a Harts technician will review these factors, answer your sizing questions, and explain which furnace options are appropriate for your home.

Depending on your existing equipment and utilities, options may include gas furnaces, electric furnaces, or dual-fuel systems. Furnaces can also vary by efficiency level and operating features, including single-stage, two-stage, and variable-capacity equipment.

They often can, but compatibility should be evaluated before installation. Ductwork, airflow, thermostat controls, and system configuration can all affect how the new furnace operates.

Warranty coverage can vary by furnace manufacturer, equipment, and installation. Harts will explain the manufacturer warranty and applicable Harts warranty coverage for your new system before installation.
