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. When Mr. RITTER was confronted he threatened to sue me while demanding he come take the furnace apart immediately on a Friday night costing me yet again another after hours service call from another company vs returning my call right away during business hours earlier in the week. Avoid at all costs.

I had described the problem and knew basically what the problem was. Felix arrived and in 15 minute had the problem located and had a replacement in his van.

Mason's was highly recommended to me by a by another business associate 25 years ago, and I have no problem doing the same. jad608

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.
