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.

We have used Master Services several times now and have been very pleased each time. Always courteous & professional, prompt & thorough. Ed the Plumber in particular has gone above & beyond to help us out. Thanks too to Jack & Kirby. Happy Holidays and thank you.

The furnace in my rental home in Lake Geneva went out and I called Master Services. The technician that they sent out told me that there was a cracked part in the furnace and that he would have to turn off the furnace because it could leak carbon monoxide. He then proceeded to show the tenant a picture of the cracked part. Unknown to the technician, she forwarded that picture to me. Later in the day, the head of the furnace sales called me to tell me I needed to buy a new furnace and quoted $7,000 for a good one. I was beginning to doubt all this and called another company for a second opinion. They came out the next morning, could find no crack in the part that Master Services did, fixed the furnace, and saved me thousands of dollars. Luckily, Master Services did not attempt to bill me for the service call after I confronted them.
I only wish I had contacted the BBB.

Jack came in gave my furnace a tune up which it has never been done. Very knowledgeable and very professional, told me about all the weak points on my furnace. I would highly recommend Master Services and will use them in the future.

Only wanted my furnace cleaned, technician said I had a weak capacitor and if went out would cost $300.00 plus to come out if went out after hours.I believe in preventive maintenance , said it would cost $140.00 since hewas was here already, only problem was he had the part in his hand, thought part cost that much, wrong its a $20.00 part, I should have did some research first. I felt he was double charging me.The company said it cost to run there trucks and did not offer anything except the $20.00 discount for being 45 minutes late and $10.00 off the early service. $90.00 cleaning turned into $250.00 I hope they honor there warranty. Bottom line its my own fault I did authorize the additional work, also for trusting Home Advisor and Master services reviews, also technician tried selling me a service contract, felt like I was dealing with a car salesman

The Master Services technician Jack informed me of all my options in detail. He was very knowledgeable and respectful. I was extremely pleased with my service call. Jack arrived on time and cleaned up after himself. He also provided me with a coupon for future services. I would highly recommend Master Service to all my friends!

I've had nothing but positive experiences with Master Services; both plumbing and HVAC. They are a very professional organization with well trained workers and they stand behind their work. I highly recommend them.
