What Chicago Says About Us
Our clients know we deliver honest work at fair prices—no runarounds, no surprises. See what Chicago homeowners and businesses are saying about their experience with DLP Mechanical.
Had my furnace go out on a Sunday night when it was 15 degrees outside. Called DP Mechanical and they had someone here within two hours. Tech was straightforward about what was wrong, gave me options, and had us up and running before midnight. Didn't try to sell me a new system when I just needed a part replaced.
Called three companies to get quotes on replacing our old AC unit. DP Mechanical was the only one who actually explained the differences between the systems instead of just pushing the most expensive option. Installation was clean, crew was respectful, and the unit's been running great for six months now.
