"Showed up early and was fast, efficient, and was able to fix our condenser after the prior company was unable to do so. Their fees were good, and they actually went out of their way to fix my problem. He informed me of exactly what he found and explained in detail of what would be the best to do to fix my AC unit. I will definitely be using them in the future and have already recommended them to friends. Great job, thank you."

"Joshua Anderegg was very very thorough and willing to bring me to the unit and have me see what was happening with my system. He had pictures and did a wonderful job explaining what was happening and what all the options were without being pushy. Very positive experience!"

"There were some minor problems with the installations - a leaking faucet (brand new faucet installed by Magic), and another brand new faucet that had the cold side quit working a day after they installed new feeder lines. However, in each case, Magic quickly sent a plumber out to fix the issues. Overall, they installed 3 new faucets, two new toilets, and four new sinks. We'll have them out again to put in a water line for our new refrigerator/freezer's ice maker, as soon as the appliance arrives."

"My deck looks great. Bamboo fencing isn't used around the treasure valley but Ben ( I think that was his name, I have short term memory problems) did an excellent job. He also checked with me if he had a question on the installation, that impressed me. Yes, I'll hire JSC handyman service again."

"I had a great experience with Yes Dear Home Maintenance as they mounted a very large TV onto a tile fireplace. The owner, Paul was prompt, professional and I would highly recommend this company. This was an intricate install and required special tools and patience to complete. Paul took his time to assess the situation before taking the first step, to make sure it was done correctly. He was very careful to make sure it was installed safely and aesthetically perfect. I will definitely call Yes Dear Home Maintenance for all my home projects in the future."
