What Factors Should You Consider When Selecting a New Furnace for Your Home?

When it’s time to replace your old, inefficient furnace, you’ll want to carefully consider all the options to find the best new furnace for your home in Tempe, Arizona. Buying a furnace is a major investment, so taking the time to understand furnace replacement is important. As you shop, keep these key factors in mind to make sure you select an optimal furnace replacement Tempe AZ homeowners can rely on for years of comfortable indoor heating.

Fuel Type

Furnaces run on either gas, oil, propane, or electricity. Gas furnaces are the most popular choice for Tempe homes since natural gas lines already run to most houses. Gas furnaces heat air quickly, have lower operating costs than electric models, and provide humidification which keeps your home comfortable. Propane furnaces offer similar perks but usually cost more to run.

Efficiency Rating

Before selecting a replacement, find the furnace’s Annual Fuel Utilization Efficiency (AFUE) rating. This measure of efficiency tells you what percentage of fuel is converted to heat. While furnaces built decades ago often had ratings below 80%, modern units mostly exceed 90% efficiency. Opting for the highest rated model your budget allows ensures you get maximum heating for minimal fuel consumption.

Heating Capacity

Carefully match the furnace output, measured in BTUs, to the size of your home. A unit that’s too small won’t keep you warm in cold Tempe winters. Conversely, oversized furnaces cycle on and off frequently, preventing steady indoor temperatures. Have a technician calculate your ideal BTU range for the best fit.

Additional Features

Today’s furnaces boast extra capabilities that enhance comfort and convenience. Consider models with variable-speed motors for a quieter flow of warm air. Built-in humidifiers add wanted moisture during Arizona’s dry winters. Advanced electronic air cleaners trap allergens and keep indoor air fresh. Determine which features matter most for your home.

Smart Technology

Many new furnaces link to smart home platforms, allowing control via smartphone, even when you’re away. Smart settings let you customize the temperature by room and set heating schedules to match your household’s routines. With a compatible smart thermostat, remote adjustments become even easier.


Reputable manufacturers back new furnaces with multi-year warranties on parts and workmanship, typically lasting 5-10 years. Extended warranties bump coverage to 10-15 years. Carefully vet options to determine whether purchasing added coverage makes financial sense for expensive repairs down the road.

Professional Installation

Proper installation dramatically impacts your furnace’s efficiency and longevity. Leave this complex job to qualified technicians who assess your home, obtain city permits, meet building codes, and test furnace operation post-installation. Prioritize HVAC companies with strong local reputations for quality workmanship and support.


With so many furnace considerations – from efficiency ratings to smart controls and warranties – having a budget in mind first helps focus your replacement search. Prices vary widely based on size, features, brand, and complexity of installing the unit. Research typical costs so your expectations align with different models that could work for your Tempe home.

Replacing an aging or inefficient furnace is a big decision with long-lasting home comfort implications. Keep these key factors in mind as you evaluate replacement options tailored to your household’s needs and budget. Taking the time upfront helps ensure you select a quality furnace replacement Tempe homeowners can truly rely on.
