Whether you are a home flipper or a homeowner seeking HVAC upgrades, you should focus on reducing cost over time instead of saving the initial cost of HVAC installation. This means you have to be careful about the HVAC upgrade options that you do on your system. In some homes, you do not need to replace the entire HVAC system while in other buildings. You only need to replace a few inefficient or faulty HVAC equipment with smarter units. In other buildings, you have to replace the entire HVAC system, especially in older homes. There is a chance that most older homes use old HVAC systems. Most of these systems are inefficient due to tear and wear or lack of good replacement parts in the market. Therefore, they need to be removed and replaced with modern, advanced HVAC systems. In case you don’t need a total replacement of your HVAC system, you need to make minor adjustments to your home’s insulation. A home insulation upgrade is not costly, and it increases the efficiency of your HVAC system significantly. For instance, fiberglass insulation costs about $1,200 and yields an average of $1,400 profit after the sale of your remodeled home. Good wall and floor insulation lower a home’s heat loss reducing the strain on your HVAC system. However, your home’s insulation won’t be much help if your building’s windows are of low quality. Spend more cash upgrading your home windows by installing double pane vinyl-insulated windows. This move will enhance your home’s energy efficiency by 74% and increase your home’s value significantly. If you replace your old home HVAC system with a new one, you need to install new air ducts. It would be best if you consulted an HVAC contractor on this matter to find the right air ducts for your new HVAC equipment.
