Wow for DOW! The DOW team installed a brand new system in my home. They were on time, clean and courteous. Also, there prices were great. I highly recommend DOW for all of your HVAC system needs. Bill B, Waterloo Il.

Super pleased with this company. I called him at 8am on a frigid morning. They had my furnace diagnosed and fixed before noon. Outstanding!!

Very pleased with the service Dow provides. Very easy to get a hold of and very prompt to repair when we have needed them. We highly recommend them!

Great product and service. My whole family has used them for many years. Very fast, affordable and honest.

poor quality, sub-standard service, installed a central air unit that doesn't cool home, shoddy follow up service ,easy to get a hold of but no follow thru to remedy the situation. would not reccomend!
