I am pretty sure my walls are not insulated. I am just wanting to get an estimate for how much you charge to insulate walls for a 1000 sq ft home. I don't know the sq footage for the walls in the home.

Smith Farm Road in Lincolnton
We just moved into an older home but a newer HVAC unit. We are looking into possibly wanting to set up a maintenance plan for someone to come maybe 2 times a year to inspect the system and make sure it is running properly. Additionally, currently we would like to have someone come take a look at the system and possibly adjust dampers if needed since we just moved in and want to make sure everything is set correctly. And lastly, we have installed a Honeywell wifi thermostat but are unsure if it is properly connected to the unit with the emergency heat. If these are items that someone might be able to handle and look at for us, could you please send me an email? My parents have been impressed with the work you have done for them so I thought possibly these are things you might be able to take care of for us. Thanks, Mindy

Sunbeam Dr. in Lincolnton
We have a 1978 ranch and I'm pretty sure the duct work has never been cleaned. My dad owned the house before me and he use to be a smoker, we also have dogs now, and I have allergies so I think I would benefit from a cleaning. However, yesterday when I checked our filters, one of them was sucked into the register, I was able to retrieve it but it made me really think about what all has been flying thru the ducts. We change our filters once a month and I don't know how long the filter was stuck (crumbled up) in the register but I know it was not longer than a month. Could we get a quote?
