Q: What are air vents called in a house?

• <div><p>Different air vents may go by other terms, including registers, vent covers, grilles, return vents, or supply vents. Registers are the moving slats that can open or close the vent, while grilles or grills are the same as vent covers, the piece of plastic or metal over the vent opening. Supply vents move the warm or cool air from the air ducts into a room, while return vents pull air from a room back to the HVAC system for conditioning. </p></div>

Q: Is rust in ductwork bad?

• <div><p>Yes, rust in ductwork is bad if it&rsquo;s left untreated. Mild rust can be removed before it causes any significant damage. However, if you ignore rust, it can affect the structural integrity of the ductwork, and you&rsquo;ll eventually need to replace it entirely. In addition, rust-causing moisture in ducts can also cause mold growth. </p></div>

Q: What happens if you don’t change an HVAC filter?

• <div><p>If you don&rsquo;t regularly change your HVAC filter, your system will get clogged up with contaminants, and as a result have to work harder to function properly. Eventually, this can cause a multitude of problems for your HVAC system and shorten its lifespan. Additionally, failure to replace your filter can lead to higher energy bills, poor temperature regulation, and even health problems.</p></div>

Q: How often should I perform a DIY duct leakage test?

• <div><p>A DIY duct leakage test should be part of your annual home maintenance routine. Conducting this test annually allows you to identify and promptly address new leaks. Regular testing helps maintain the efficiency of your HVAC system, reduce energy costs, and ensure a healthier indoor environment by preventing leaks from going undetected for extended periods.</p></div>

"very poor work quality, I had to have them come back 3 times after the initial installation to repair damages and fix the shoddy workmanship to get the roof right and it still hasn't passed Inspection. On top of that on three other occasions they were scheduled to be there and they just didnt show up at all. They left trash in my yard and in my driveway causing a flat tire on my car due to nails left all over the driveway. I even found missing shingles on a newly installed roof, how does that happen? I also found out after the fact they were TWICE as expensive as their competitors. I called 3 different contractors after getting their final bill and found this out. Twice the price for shoddy work? I'm just glad I was able to get up on the roof and check the quality of the work and demand they corrected it. My recommendation, hire someone else. There are so many other capable company's out there. You dont need to waste your time with this one. It's not worth it."
