Q: How can I cover my HVAC ducts and air vents during construction?

• <div><p>To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.</p></div>

Q: Do you need a vapor barrier under metal siding?

• <div><p>When installing metal siding, a high-quality house wrap is considered the best protection against condensation and moisture infiltration. House wraps can increase a home's efficiency significantly. However, a house wrap is not a replacement for a vapor barrier because it can be permeable when moist air passes through siding. This is why it's essential to follow manufacturer instructions for insulating siding when installing new siding.</p></div>

Q: Can you put insulation on top of ductwork?

• <div><p>Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.</p></div>

Q: Can you have too much insulation in your home?

• <div><p>Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to &quot;breathe&quot; or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.</p></div>

Q: What is best to put on windows to keep cold out?

• <div><p>To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.</p></div>

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."
