"Probably one of the best customer experiences I’ve ever had with an HVAC company. I’d recommend them 10 times out of 10 without a doubt!"

When was the last time a professional looked at your heating system?

Your heating system requires annual heating tune-ups from a professional HVAC technician to keep it running right. In fact, a tune-up doesn’t just help you prevent a breakdown, but can actually boost your energy-efficiency and extend your system’s lifespan.

Here at Dufrene’s, we tune up furnaces, heat pumps, and ductless systems here in Lockport, Larose, St. Rose, and other surrounding communities in South Louisiana.

Ready to get your heating system tuned up? Use the form to contact us, or call us at (985) 532-5841.
