Hello, We discovered that the home we purchased recently does not have enough insulation in the attic. Additionally, we noted that there were pests in the attic too. I am looking for a quote to install new insulation in the attic. The pest control we choose will remove the old insulation and sanitize the attic. The attic is approximately 600 square feet.

I have a 22 year old furnace that I'm thinking of having replaced. It's a Bryant Plus 90 350MAV048100. My home is two stories, 4 bedrooms with a large family room attached to the main dwelling. I would appreciate a ballpark estimate (a couple of suggestions) for the furnace replacement. If I like your estimates, I'll arrange to have you come see the current installation. The AC is newer and will not need replaced. Thanks.

I have two AC Units both are Lennox models and are 12-13 years old.

I have turned-off the 3 Ton so we are out AC on the first floor. Can you have someone contact me asap.
