DUCT SEALING & INSULATING - GRILLS & REGISTERS
Be sure your ducts are delivering all the warm air they can!
According to EnergyStar, about 20% of the air moved through duct work is lost through leaks! Leaks should be sealed and ductwork in a cold basement, crawl space or attic should also be insulated!
Suggested ductwork improvements:
Check, measure and identify all duct leaks
Seal duct leaks and seams with mastic sealant or metal tape
Replace or repair and damaged, disconnected or undersized ducts
Straighten out or replace any crushed or twisted flexible ducts
Seal all registers and grills tightly to the ducts
Insulate all ductwork in unconditioned spaces with an R-8 duct insulation...which is NH code!
Be sure your HVAC system has adequate return air to keep your home balanced. Negative pressure can draw carbon monoxide from gas appliances in homes with inadequate returns. A carbon monoxide detector is highly recommended.

"We were so lucky to have found such honest people! The Card's came to our house twice quite late at night to work on our furnace which we greatly appreciated due to our "out-of-date" furnace. Our basement was an absolute nightmare until Mike's sons installed new (neatly fabricated) duct work as well as a new furnace. I would strongly recommend Card Heating & Cooling! They take pride in their work and do a fantastic job! Thank you Card family!"

"Mike, I just wanted to let you know...we decided to go through an energy audit for the house (nothing related to the heat - we just wanted to be more efficient. Anyway, the point is, the fellow came today and did a bunch of tests on the house. He commented (several times as a matter of fact) about how well done the duct work was, how well the heating system was tuned, etc. etc. One specific comment from him was that the ductwork you did is 'exceptional' and the state of the burner was much better than he's used to seeing in a typical home'. I just thought you'd want to know. Thank you for all your had work...being a homeowner, it's hard to know an exceptional job vs. an average one. But since this guy's job is to inspect these things, thought you'd appreciate what he had to say."
