Our Customer's Have Spoken

It had been years since we had our HVAC serviced. I called Master Mechanical because their service sticker was on the unit. I know that sounds like a weak reason to select a service company, but the HVAC had been running fine for years, so clearly they couldn't be all that bad! It turns out they are wonderful. We were given a two hour window for the appointment, but the owner Tom showed up exactly at the beginning of the appointment. We were expecting all sorts of bad news because we hadn't been doing any routine care. He reassured us and quickly went to work cleaning the unit. Only one small part needed to be replaced. I feel that the price he charged for both the part and service was very fair. We were very pleased with the service and plan on using Master Mechanical again.

My AC stopped working last night. Called Tom from Master Mechanecial at 7pm, he called me back within 5 min. An appointment was set for today. Tom arrived on time, he quickly diagnosed the issue and gave me the quote right away. His professionalism and friendliness buycialisonlineworldwidestore.com were impressive! Especially he saves us on this hot weather:) Thank you Tom!!!

Master Mechanical is all about Customer Satisfaction! Melissa was very kind on the phone when scheduling my appointment. Tom and his associate were on time to my home. Tom was very detailed in explaining my options with my air conditioner. I will always recommend Master Mechanical. Thank you.

Great find! Quick and timely service. Very knowledgeable and friendly. Came to fix our furnace because it wasn't turning on properly. He explained the problem to us and fixed it right away for much cheaper than the handyman estimates we received! He also was very helpful and answered some questions we had about our humidifier. We were very happy with the service and will definitely be using Master Mechanical again.
