"My furnace went out on a very cold winter's day. I thought I could make it through the night without the heat, but by the time the temperature inside dropped to 62 degrees I gave up and called Wm Masters (in the evening.) The service tech came to the house at 9 p.m. He discovered the igniter had gone bad. He had another one one on his truck, and he replaced it for me. Problem solved! He also took time to talk to me about the furnace and the humidifier attached to it. He didn't try to sell me anything--just gave me good information. I have had Wm Masters do my plumbing, heating & air conditioning work ever since my husband passed away, and I've always been happy with the end result. They have a reputation for being expensive, but my personal opinion is that you get what you pay for, and Wm Masters has always been worth the cost in my book. I've been very happy with their service."

"Everything was perfect. I left a voicemail and he called me back within minutes. We discussed my problems and he understood my computer gibberish. He came to my house to pick up the laptop. He notified me that night about the cost of the replacement parts and length of shipping. He then contacted me when my computer was fixed. He delivered it to my house.

"On estimate
Rich was prompt, friendly and professional. He was straight with me and honest. 

Another HVAC company told me I had to install pumps to each unit (I have 3) to help the flow of water (a total of $600). Rich explained to me that all that was needed were some "T" pvc for venting ($0.39 each) that he had on hand. Since it was a quick task, he put them in for free.

He gave me a price that was $1,200 LESS than another estimate.

On the work
He called the day before letting me know the weather looked bad on the day of the install - depending on the weather, he might have to do it the following day. I really appreciated that notice given I have tenants. It was very professional.

When the weather was better, he showed up- as promised - and he kept in communication with me.

A few hours after he left it wasn't cooling the apt. We chatted by text even though it was late. He came out the next day without complaint and fixed the problem. All the while keeping me informed.

Overall
Although the install was a bit bumpy, he never complained, was considerate, easy to work with and treated me very well.

He has earned a customer for life.
