Furnace Replacement

The furnace you have now may not actually be the right size for your home. It’s not unusual for older systems to be oversized or undersized from the start, and changes like a home addition, new insulation, or updated windows can throw off what size you really need. A furnace that’s too small will run constantly but never get the house warm. One that’s too big will cycle on and off, creating uneven heating, more wear on parts, and higher bills. We’ll measure your home, factor in insulation and square footage, and make sure the replacement is sized properly.

AFUE—Annual Fuel Utilization Efficiency—is how we measure how much of the furnace’s fuel gets converted into heat for your home. For example, a furnace with an 80% AFUE rating turns 80 cents of every fuel dollar into heat, while 20 cents is wasted. Many older furnaces in Austin are in that 70–80% range, while modern high-efficiency systems reach 95% or more. That difference adds up, especially with Austin’s cold snaps in the winter. We’ll go over what efficiency levels make sense for your budget and how much you could save in utility bills with a higher-efficiency model.

Today’s furnaces come with features that older systems never had. Variable-speed blowers adjust airflow to keep temperatures more consistent and reduce noise. Two-stage and modulating furnaces can run at lower settings most of the time, saving energy and preventing big temperature swings. Smart thermostats let you control the system from your phone and track your energy use. Zoning systems allow you to heat different parts of your house separately, which is a big plus in multi-level homes. We’ll explain the options and help you decide which features are worth investing in.

We encourage you to contact us about your furnace replacement in Austin as soon as possible. You don’t want to be left without heat when temperatures drop into the 20s. Scheduling your furnace replacement early means no last-minute stress—and a warm, comfortable home when it matters most.
