Installing a new HVAC system is a big investment, and when done right, it keeps your home comfortable for years. But when mistakes happen during installation, you might find yourself dealing with inefficiencies, higher energy bills, or even system failures way sooner than expected.
One of the most common mistakes is choosing the wrong size unit. Bigger doesn’t always mean better, and smaller doesn’t necessarily save you money. An oversized system cycles on and off too frequently, leading to excessive wear and tear, while an undersized system struggles to maintain the right temperature, making it work harder than it should. Proper load calculations should always be done to ensure the unit is the right fit for your home.
Ductwork is another area where things often go wrong. Poorly designed or leaky ducts make it difficult for air to reach all parts of the home evenly. If some rooms always feel too hot or too cold, improper ductwork could be the culprit. Sealing and properly sizing ducts is just as important as installing the unit itself.
Installation shortcuts can also lead to trouble. Skipping important steps like proper refrigerant charging or not securing electrical connections might not cause issues immediately, but they can lead to reduced efficiency and costly repairs down the road. A well-installed HVAC system should run smoothly and quietly—if you notice loud noises or weak airflow from the start, something was likely done incorrectly.
Another mistake that can cause long-term problems is poor placement of the outdoor unit. If it’s installed in a spot with poor airflow, like too close to a wall or surrounded by overgrown vegetation, it won’t be able to expel heat efficiently. That means your system has to work harder, which can lead to breakdowns and increased energy costs. Regular maintenance, like keeping the area clear of debris, also helps keep things running smoothly.
Lastly, one of the biggest issues is improper insulation and sealing. If the home isn’t well insulated, even the best HVAC system won’t be able to keep up. Air leaks around windows, doors, or even in the attic make it harder to maintain a comfortable temperature. Sealing up those gaps can make a huge difference in overall efficiency.
A well-installed HVAC system should provide comfort and reliability, but small mistakes can add up quickly. Working with experienced professionals and taking the time to ensure every detail is handled correctly will save you money and headaches in the long run.
