Customers say: Quality work
"Mereson did clearance testing after asbestos flooring was removed. Geoffrey was helpful, friendly and worked with us to get our sample tested and our results back quickly. His services were also very competitive priced. Would definitely work with him again."

"Michael Kuretich thoroughly tested the inside and outside of the house for lead paint. He took many samples from linoleum glue (black tar) on different surfaces and had them tested for asbestos. He came back a few times and tested the air after the removal of lead-containing bathroom tiles and flooring that contained asbestos in the glue. He did not charge me for one of his visits and inspections. His price is really fair while maintaining quality. He is knowledgeable ang gives sound advice. I used one of the companies he recommended for lead and asbestos removal and I was very happy with their work as well.
Another company listed with Angie's List wanted much more for the same service. When I asked why, he said that is the price for and quot;wall-to- wall testing.and quot; Please watch out for crooks.
I highly recommend him.

"I thought the job was very well done. They explained the cost before starting and did a great job! But, didnot inform me that there was a minimum charge of $249 until after they itemized the price for each item; I ended up paying an extra $54 which could have been applied towards more vents to clean. However, I am very pleased with the work done. Our heater motor really needed to be cleaned well as was done. I was just disappointed they did not tell me about a minimum charge of $245 after telling me each detailed cost of each type of service. Be sure to get a clear written quote before starting your job. I was also not offered the 5% or given the discount for using angieslist.com. I will consider another company next time."

"We were very happy with Yurik and his install team. Prior to install he came out to do a comprehensive onsite estimate, free of charge. He went into the attic space, checked the existing furnace, recommended a compatible AC unit, and gave us recommendations on running duct work to the additional rooms. He was very up front with us that the existing furnace and the compatible AC unit were right on the edge of being able to handle the volume of space we were asking, but we were comfortable with that. He estimated that the entire contraction would take approximately 7 days.
Once we decided to move forward, Yurik?s team was on site on time and ready to work every day. Each day they draped the floors to keep the mess down, and were very good about picking up after themselves.
Hi team was very efficient, and was able to get the job done in half the estimated time. All the new ducts are sealed nicely, and each register is clean.
Yurik?s team also installed dampers in each of the ducts, to help regulate the air flow to the new portion of the house and the original and they took the time to properly calibrate the dampers so that each room is nicely balanced. The whole house now benefits from central heat nicely (we tested the AC, but as it?s winter we won?t have a solid test for a few months).
One thing to note is that they are definitely quicker to respond to phone/voicemails rather then email. Not a horrible problem, but if you want a quicker response that?s the way to get it.
I would definitely recommend UMC for AC work, and we?ll be using them to service the equipment in the future.

"I was looking for a contractor to do an overhaul on my mom's house. I was very happy to have worked with Tomer, he is a really smart guy and gets the job done right. My mom is a bit of a nitpicker, but Tomer kept his cool throughout all her questions, even after hours. The crew Tomer keeps do precise and amazing work. Tomer really listened to what we wanted the final outcome to be, but let us know what parts of our ideas would not be realistic. The outcome is stunning. Friends and family have been very impressed. I'm happy my mother can spend her last few years in this beautifully remodeled space."

"A lot quicker than originally estimated. The job was quoted and finished within a week's time. The quoting process was efficient with no runaround or bs. Very straightforward this is how much things cost and here's why - very reasonable and honest people to work with. The job was done with high quality materials and excellent workmanship."

"We had several issues that caused us to contact a company that can come over and check our house for any problem that can be solved and reduced our utilities bills. We contact this company and we asked them to come over and see what they can do. Avi came over and explained to us how they work and what they do in order to determine what can be done. The initial work included sealing all the openings in the house and then they made some tests with special machine that made a clear picture that our air conditioning system have some leaks that causing the system to work extra time. After they completed the testing, Avi came over with another crew of workers and fixed the ducts making sure that there will be no more leaks from that area. The work that they did was good because they made a massive testing before they came to the conclusion about the air conditioning ducts.
