Then Brad was great, calling me after his visit to explain his findings and make his recommendation.
Brad is kind, possesses excellent customer service and is very respectful. He prepared several options for my husband and I to discuss. Brad even extended the option for him to come back out to meet with my husband face-to-face before we invest thousands of dollars into this needed project. Thank you, Brad.
Kudos to Brad and Allied!

Furnace Repair FAQ's
How long does a typical furnace repair take?
Most repairs are completed in one visit, usually within one to two hours. The exact time depends on the part that failed and the furnace model.
How can I tell if my furnace needs repair or replacement?
If your system is over 10 years old, needs frequent repairs, or struggles to heat your home evenly, replacement may be the better option. We provide honest recommendations after inspection.
Do you service all brands?
Yes. Our technicians are trained to work on all major furnace and heater brands, including Lennox, Trane, Carrier, Goodman, and Rheem.
How often should I schedule maintenance?
Once per year is ideal. Preferably in early fall before the heating season begins. Regular furnace maintenance helps prevent breakdowns and improves efficiency.
Why is my furnace making loud noises?
Noises like banging, squealing, or rattling can signal loose parts, a failing motor, or airflow issues. A technician should inspect it immediately to prevent further damage.
