Customer Reviews
What our customers are saying

Christian Bierkamp

I’ve used Maglish twice now for plumbing services. Everyone I’ve dealt with was polite and professional and has shown good quality of work. They cleaned up well after the job too and were mindful of my pets being inside.

Gretchen Collins

Our air went out for the hottest day of the year, they had a tech available for the next day. Worked fast, my husband thought what he was quoted was for the part alone (blown capacitor) but that was the total, the part and labor. Very reasonable. We’ll be using them from now on.

Jacob Toodle

Tim came over and help my mom with the A/C while I wasn’t home! He did such a great job,, positive attitude,,great body language and hard working! I appreciate his work and I appreciate Maglish!

Mo P

In these challenging times, and with a gallon of gas at almost $5.00, Maglish technicians still provide excellent service and competitive prices. Tech Tim did a fantastic job on our a/c system service/repair.

Susan Kelley

Tim was very professional and helpful. Answered all our questions. Will be happy to see him in the spring for our AC maintenance. RJ installed our hot water heater, also very professional and helpful. Very impressed with these two professionals. Thank you

Al Odanovich

Maglish is a life saver! Tim & Nate came out and replaced both AC and furnace. They did a great job, were fast, clean & professional. I’d highly recommend to all my friends and family.

Kel R Bandy

I was thoroughly impressed with Maglish and will definitely use them again. When I called to schedule an assessment for a minor issue with my furnace, the receptionist was very courteous and set up an appointment easily. Tim arrived on my appointment day and was very professional and friendly.
