Was hesitant even scheduling service with the ""small service fee of $129"" they charge just to come out and take a look. I should have listened to my gut. No wonder they charge the service fee, or they wouldn't have any business.

I have a small leak in my refrigerator water supply line and they quoted me just shy of $300 for that (which includes the $129 service fee). Frankly too expensive for the less than 45 mins worth of work, but the $129 is non refundable. Then I asked them to look at my gas line for my new stove that was slightly leaking and they quoted me $500 to hook up a new gas line. When I asked the tech why it costs that much, he has no answer besides ""that's just how much it costs"". The tech had no personality, came across rude, and took a personal call on the job. Horrible service and frankly a rip off. I will never use or recommend them.

They grossly overcharge on parts & labor. They suck you in on ""service contracts"" which are ridiculous, just an in to try & scare you into spending even more money. They completely price gouged my disabled son after being loyal customer for years. I had to report them to the BBB to get a LARGE refund & even then they BS'd about our ""negotiations"", disgusting behavior. They are snake oil salesmen at best.

I am very happy with Master Services. I live a distance away, but they still came to my home without complaint to give a very thorough estimate for a new furnace and duct cleaning. The technicians arrived right as scheduled, with text and phone alerts before arrival, did all their work AND cleaned up like champs. I have a great new furnace that is so efficiently warming my house that I turned my thermostat down a degree. I also appreciated the military discount! Thank You, Master Services!

Requested service of older AC unit.

I was comparing fix old vs buy new and asked for new unit pricing. He couldn't provide that to me without another tech ""house assessment"". I said ballpark to replace with the size I have...no he couldn't give me a range even. But asked me what I ""thought it should be"". I already did research so knew but this game was insulting. He went through some service old calculation on his phone that was inaccurate and truly a waste of time exercise.

I was told he needed to speak with my husband. I said I was the ""handyman of the house"" and he was not home anyway. I was informed this would be a major expense so he would need to speak to my husband either live or on speakerphone. I said I handled all house maintenance so let's discuss.

The conversation was surreal like I was thrown back into a Leave it to Beaver episode. This is 2022. I don't need permission or approval to spend $ and do not appreciate the condescending context period.
Needless to say I will not be using this company to replace the unit and wish I had read the Yelp reviews first anyway.

So yesterday I wrote a review because the furnace technician left my basement flooded. Turns out while he was down there "" doing maintenance "" on my furnace, he broke it. A fully functioning furnace, only 10 years old, overnight no longer heats the house. I'm getting a lawyer! Don't let them in!!!

Danny was very respectful of Covid and showed up in mask and gloves, watched him wipe down things he touched. He did a thorough job, was pleasant and couldn't beat the ""special"" rate.

Master Services lost my business due to a dishonest employee after a recent repair. Be careful when you use them. I am disappointed that they lost a good customer because of one person. They have some great employees but one person can ruin your reputation.

Update: The General Manager followed up with me on this issue and assured me this will not happen again. He took responsibility for their mistake and they sent someone out to test my AC to ensure no damage occurred. They will stand by their work and apologized for the issues. I appreciate the follow up. Thank you, Serhij.
