The tech fixed the issue and then charged OVER $800 PLUS SERVICE CALL TO REPLACE A $35 PART. $35 was the OEM cost through the company site.

Staff on the phone has always been personable, prompt, and courteous. Mason's is a top-notch outfit, the likes of which you just don't see much anymore these days. They replaced the A-coil and outdoor condenser unit for our non-working central air, and they did it for substantially less than any other estimate from the well-know big brand names in town. Mason's was highly recommended to me by a co-worker, and I have no problem doing the same. Call Mason's before you decide to go with any other HVAC business, and I bet you won't regret it.

I had some challenges with a recent gas-leak repair strikingly similar to Lauren S. When I…read morescheduled the appointment, I was told a written estimate would be provided before work began and that the total cost would likely be around $400-$500, based on a rate of $185 per hour for labor. The final bill, however, was well over $2,000. I was not provided an estimate on site. Two technicians were sent, and it turned out that the billing was calculated at $185 **per person per hour**, including drive time that appeared longer than travel time at rush hour from their headquarters according to Google. After reviewing the invoice, I had to seek legal advice and confirmed through an independent witness that the technicians were on site for only a few hours. We ultimately reached a resolution after considerable back-and-forth. I would recommend asking for a written estimate and a clear explanation of hourly billing before authorizing work. Write down everything and do not proceed unless you have a written estimate you agree with.
