Duct Sealing To Keep Bugs And Rodents Out

October 18, 2015

An infestation of bugs or rodents is something no homeowner wants to have to think about, but no matter how clean you keep your home, the potential for pests to invade your space is always there. Duct sealing your home’s HVAC system is an affordable and effective way to keep pests out.

Pests can pose a threat to your health and the health of your family members. Mice chew through insulation and other property as they gather materials to make nests. They can use your duct system to invade all parts of the house. Even the smallest gap in a vent or duct allows pests to access to your home.

Many pest control products contain dangerous poisons that pose their own threat, especially to pets and small children. Another disadvantage of using pesticides is the chance the animal will crawl deep into the walls or duct system and die there. The foul odor created by the decomposing body spreads throughout the house when the air conditioning or heater is running.

Traps offer another alternative to putting down poisoned bait. You can place traps inside the duct. Check them daily and dispose of any dead pests you find.

Sealing your ducts offers additional advantages beyond just stopping pest infestations. When your ducts are properly sealed, your heating and cooling system will run more efficiently during the winter and summer. Heated and cooled air is distributed evenly throughout the house eliminating hot or cold spots. You can expect to see a decrease in your monthly utility bills because your system does not have to work as hard to maintain a comfortable interior temperature.

If you have a problem with pests, an experienced HVAC technician can inspect your system and identify any leaks in the ductwork. Sealing the system properly provides an effective way to keep mice, rats and insects from getting inside your house. At the same time, your heating and air conditioning system works at peak capacity making your home more energy efficient and comfortable.

David M and Michael S were both very detail-oriented with exceptional customer-service mentalities and communication skills. They clearly described their findings and what services they would be able to offer. I felt confident that they had thoroughly investigated our HVAC system issues and considered all possible solutions before offering their recommendations. Moreover, they provided recommendations in a manner that did not feel as though they were pressuring us into making a purchase on-the-spot but rather allowed us to come to a decision on a timeline that worked for us. As a team, they spent multiple hours evaluating our HVAC system and left no stone unturned or question unanswered.

Google does not allow multiple reviews, so editing this to update on the most recent visit.Jason and Armando were assigned and did a fantastic job. They were prompt, courteous and professional. They upheld the high-expectations that I have for Brody Pennell. They were both super friendly and through. They covered all of the expected work and also looked into another issue I was having. They were both able to provide solid advice on how to proceed.From a business standpoint, the scheduling, confirmation, and information regarding the visit was top notch. I felt informed every step of the way and the information was accurate.%%%%%%%%%%%%%%%%%%%%%%%%Review from 2023:This review is specific to the HVAC maintenance repair completed this spring. I setup the appoint and received confirmation and a reminder the day before. Once the technician was assigned, I received additional communication that they were on their way.Jose C. arrived and was prompt, courteous and professional. He chatted with us first to talk through what he was going to do, got a lay of the land and then went to work. He took time once he was completed to share his findings, the work he did and discuss next steps. He captured photos of the before and after and documented his work well.He also took the time to call dispatch/office to clarify some confusion, which was great. All in all, great experience from start to finish.

I had to take the time to update my review and thank and compliment Ashton K. and his team of installers Mike, Raul, Elario, and Juan DS who installed our new furnace. Ashton’s knowledge and follow up has been fantastic. The installers workmanship was excellent. They were all professional and respectful and kept our home neat and clean after they finished the installation. The furnace is working perfectly. Our follow up appointments with Jose Rivera, Jonathan A. and Ramiro S. were also handled with the same professionalism.I would highly recommend Brody Pennell. The quality of their furnaces and workmanship are excellent.Juan Molina and Ashton K provided me with great service today. They were both very thorough and detailed in explaining the technical problems that were occurring with my heater. I was very pleased with their high level of service and professionalism.

Today when we had someone come to look at our ancient HVAC, I never imagined that we could be shown in great detail the inner workings of the thing. David Mars with his kit of diagnostic tools and his supervisor Fabio Lopez (I think is Lopez) showed us in photos and videos (even with a tiny camera on a gooseneck that showed inaccessible parts) and explained at length the significance of all the horrors we were looking at. We are now scheduled for installation of a new HVAC tomorrow. I’ll post again if my experience changes but so far we are impressed.

I really enjoy the service guys here. David and Alex were really lovely and the last time Benny was so great. I was already planning on getting a new unit. Wasn’t a huge fan of the particular supervisor I dealt with in terms of sales, but we were able to finalize with Michael and I would like to believe we all have bad days. Michael made us feel much more confident. I will update when I have my new system. I do always appreciate that they are very respectful and adaptive to my medical needs.

Marco Ayala (technician), Juan U. (apprentice) and their supervisor Ashton were courteous, patient and thorough. They reviewed the problems I have with my Carrier unit and explained why I needed it replaced. I was given the choice of 3 new models with price and labor for each. They offered to contact my HOA’s management company for the roof installation and will arrange a city inspection after the work is completed. I would not hesitate recommending Brody Pennell to family and friends.
