The ventilation method at our lake house is arguably the worst I’ve ever seen. Of the 4 different houses I’ve called lake lake house in the past 20 years, I’ve never had to worry about hearing pigeons flying around within the ductwork. I’ve also never had to listen to pecking & biting between said pigeons & rats, at all hours of the night! After dealing with the war between flying & grounded rats for the past few months, I’ve had our fill – & saved the necessary funds to pay for pest control. Once I paid to have the exterminators come by the house, they went upstairs & got to job removing the pests. Midway through, 1 of the exterminators came down to tell myself and others that I’d better go ahead & schedule an appointment with a heating, ventilation & air conditioning dealer to get a quote on vent renovation. I knew it was really going to need some patchwork to deal with whatever damage the pests caused, even though I didn’t believe the entire duct method had to go. Well, when the exterminators were done, they had myself and others come upstairs & take a look at the ductwork. I couldn’t believe the damage that these stupid rats & pigeons did to the ducts! There were softball-sized holes in the ducts all over the arena where the rats chewed their way in & out. I was certainly going to have to prepare for getting the entire duct method updated. I sure hope the Heating & A/C Company lets myself and others make payments over time, because there’s no way I can afford to pay for an all-new duct method up front! The exterminators recommended a dealer they often job with, & said he usually lets his shoppers pay installments for services.
