Best Air Duct Repair in Madison WI

These guys handle all my work -- both for my company and for any personal needs that I have.  They are experts, with quality work, and fair prices.  They can handle the replacement jobs, hydronic work, and even solar hot water.  They leave my customers satisfied!

TL;DR - Overall:  Average Rating.  While basic service was good, they seemed to struggle with meeting our expectations around a reasonably significant mistake on their part.

All Comfort provided good service and work for the furnace installation in my home; however, for a business with their ratings and standards, their actions handling a gas leak they were responsible for seemed less than adequate to my wife and I.  The break down:
-The technician finished the job close to noon, explained final details of the installation, and I left for work the rest of the day.  My wife and I came home to the smell of gas in the house about 6 hours later.
-The fire department came out with Madison Gas and Electric and determined there was a leak.  All Comfort was soon there to resolve the issue.  It was determined that the technician did not appropriately install a section of new piping.  This was admitted by All Comfort and they said the technician had additional training about the situation to avoid it in the future.
-Based on the severity and risk of the situation, I decided the appropriate response from All Comfort should have been to refund the cost of the labor.  The furnace and the thermostat worked fine, really the only issue was with the labor.  Considering it wasn't something minor like the furnace not starting, I thought a pretty significant compensation was appropriate.  All Comfort offered $100.
-After doing research, it appears that instances like this are very uncommon (only about 2 to 3 gas leaks per company out of hundreds of installations per year) and I didn't feel that it would have really hurt their business to just admit they made a mistake and eat the labor cost out of good will for their business and customers.
-However, research also showed that generally, most companies offered nothing beyond having their techs come out and fix the problem.  All Comfort arguably could be considered above local standards in this regard.  Also, no damage was done and nobody was hurt.
-After speaking further with All Comfort and explaining my reasoning, they were willing to offer $150 in compensation.  We agreed to take it but still feel this was a weak gesture.  They sent the check with an apology note.

To top it all off, they sent an apology letter with an All Comfort clock that didn't work because the battery they included was dead.

About 3 years ago we had a new hot water heater installed by Ryan Heating. Today upon inspection from Alliant Energy we find out that Nothing in the vent system installed was done to code. That isn't even the worst portion. Since the venting was not done properly the basement has been filling with Carbon Monoxide and likely portions of our home as well. We are lucky that this didn't result in a worse outcome but as none of the numbers are even connected anymore there is no way to contact them to resolve this issue. Could have been deadly. Deserves negative stars.
