Hello. My name is Max. My wife and I have five children who all live at with us in our large two-story house. My wife and two of our kids suffer from severe allergies which means keeping our home as dust-free as possible. I have learned that it’s crucial to keep our heating and air conditioning units properly maintained at all times. We have a fantastic HVAC company that comes out two times a year to perform routine maintenance on our system. They have taught me what I can do on a monthly basis in order to not only help with my family’s health but also keep our system running efficiently. I would like to share some of the tips I’ve been given. I hope you find this to be useful!
Your HVAC system is made up of your furnace, air conditioner, and ducts. You might not give the ducts much thought, but they can need to be repaired or replaced too. If your ducts don't work properly, your HVAC won't keep your home comfortable and you'll drive up your power bill. Here are some problems that develop with ducts and the HVAC services they could need.
Deterioration Due To Age
Your furnace and air conditioner could last a lot longer than the ducts, so it's possible you'll have to replace the ducts due to old age. When metal ducts get old, they might rust and develop holes. Flexible ducts might get crushed or torn.
When these problems develop, the HVAC repair technician might recommend replacing the ducts rather than trying to repair them, especially if you want several years of life from the ducts.
Destruction By Animals
If a big raccoon gets in your attic to get warm over the winter, or a bunch of mice decide to move in, the animals could do a lot of damage to your ducts. Animals can shred flexible ducts and use them for a warm nesting area. A raccoon might be able to tear open a metal duct.
Once the ducts are open, the animals get inside and breed and leave droppings behind. Your ducts are not only destroyed, they become toxic. An HVAC technician might recommend replacing ducts animals have destroyed, but it might be possible to have the ducts cleaned, sanitized, and patched up depending on the extent of the damage.
Air Loss Through Gaps
An HVAC service that might be offered is a pressure test. This helps the technician determine if there are leaks in the ducts. Leaks drive up your power bill because the AC or furnace has to run longer to meet the setting on the thermostat.
The repair technician might be able to repair simple leaks in ducts depending on the location of the leak and the type of leak it is. Duct tape is a good temporary repair, but a more permanent option would be to use mastic sealant. Your repair technician might also use an aerosolized sealant to seal leaks in areas that are hard to reach to apply the mastic sealant with a brush or caulk gun.
Foul Odors Due To Mold
Mold is a problem when it grows inside HVAC ducts because spores get blown all through your house. Plus, the inside of the ducts is hard to reach and clean. Mold can get in your ducts if you have moisture problems in the attic or if you've had a mold problem elsewhere in your house.
The HVAC technician can assess the problem and decide if it's better for you to remove the old moldy ducts and put in new ones, or if the mold can be cleaned out and the ducts sanitized.
