I’ve called other A/C repair guys in the past…but decided to call Big Will’s A/C and Heating that a friend referred. His prices are very reasonable and he is one of the nicest guys I’ve ever met! He was honest, gave me options, and was very knowledgeable about my type of unit. I was so impressed with him and his pricing, I went to work and sent out an email to my co-workers, telling them about Big Will should they ever need a HVAC guy!

Will replaced our blower and capacitors the for $1000 less than the bigger company’s quote. He showed up at 9 a.m., checked everything out, left to get the parts, and came back to finish the job. A+ service!

Called Big Will after realizing my AC was out at 7 in the morning. He was there a couple hours later and had me up and running that same day after replacing my outside unit. Fast reliable and friendly. Great person that does great work.

It’s was 57* in my home this morning due to the ice storm. Big Will answered his phone (on Mardi Gras), arrived within minutes and had my heater running shortly after. This dude is awesome. Highly recommended.

Will has replaced 3 units for us (none that he originally installed) over the course of several years. He always shows up to check out a unit on the same day we call him. He always gives us his honest, professional opinion, and we’re always satisfied with his work.
