The nice thing about Duct cleaning Twin Cities pricing is that it is all flat rate. There is only one exception and that's for transient vents (in-floor heating). when the technician is out, he will make recommendations and you can decide if you want to clean other items while we are out. For example, the duct cleaner may notice that your chimney has a lot of soot, or your dryer vent is nearly clogged.
We clean a lot of duct work for people who have either just moved into their new home, or have just had a baby. We also clean a lot of furnaces in the fall and do a lot of air conditioner cleaning in the spring.
Ask the duct cleaning company if you can write the check out before they arrive. If the duct cleaner is legit, they should be able to give you a real price over the phone. Many dishonest vent cleaners will leave if you are unwilling to spend more than the quoted price. An honest air duct cleaning company will do the work for the advertised price and won't try upsell you unless you want them to perform other services.
