Professional Furnace Installation Services

The best furnace for your home starts with careful planning. We perform a heat load calculation, review ductwork and return air, confirm gas or electrical supply, and verify safety controls before final start-up testing. Proper sizing helps prevent short cycling, uneven temperatures, and unnecessary wear, which can help lower utility costs and extend equipment life. You get clear options, upfront pricing, and a tidy installation from start to finish.

We also focus on the details that improve comfort day to day, like thermostat setup, airflow balancing, and verifying that your system is delivering consistent temperatures across the home. If you want quieter operation and steadier heat, we can help you compare features like variable-speed blowers and staged heating so you can choose what fits your comfort goals.

Gas Furnaces

Natural gas offers strong heating performance for cool Hill Country nights. Our gas furnaces are selected for efficiency and comfort. We check venting, gas pressure, combustion, and carbon monoxide safety during setup and maintenance. If you notice a yellow burner flame, new odors, or a furnace that struggles to ignite, it is time to schedule service.

Electric Furnaces

No natural gas line in place? An electric furnace can be a dependable solution. We verify electrical capacity, match the heater to your home’s needs, and set airflow for quiet, even temperatures. Electric furnaces can also pair well with other efficiency upgrades, like improved insulation or duct sealing, to help reduce overall heating demand.

Furnace FAQs

How do I choose the right size furnace?

We run a heat load calculation that accounts for square footage, insulation, windows, and ductwork. Correct sizing helps improve comfort and can help reduce energy use.

Is repair or replacement the better value?

We look at age, repair history, efficiency, and safety. If a repair can restore dependable heat at a fair price, we can recommend it. If replacement can reduce repeat failures and improve efficiency, we can show options that fit your goals.

How often should a furnace be serviced?

Once per year before heating season. Maintenance includes safety checks, cleaning, electrical testing, airflow verification, and thermostat calibration.

What efficiency should I look for?

Higher AFUE models can help lower operating costs. We can help compare efficiency gains with upfront cost and your usage patterns to find the best fit.

Do you work on both gas and electric furnaces?

Yes. We install, repair, and maintain gas and electric furnaces, including variable-speed and staged systems.
