Each year, about half of your energy bill will be devoted to heating and cooling costs. Unfortunately, many homeowners overlook how important it is to maintain and repair their heating, ventilation, and air conditioning (HVAC) systems.

Three million HVAC units are replaced each year, and around $14 billion is spent on HVAC repairs. By being smart about your HVAC installation and maintenance, you can reduce your long-term costs, avoid unexpected breakdowns, and become more energy efficient. Through the help of a trusted provider offering fast AC maintenance services, you can avoid common HVAC mistakes during renovations and home updates.

1. Failing To Plan HVAC Systems Early in the Renovation Process

One of the biggest mistakes people make is not doing any HVAC planning for renovations. As you change the location of your walls and add in new windows, you’ll need to rethink the way your HVAC system is placed. Additionally, you should consider where your ventilation and ductwork are.

When HVAC systems aren’t placed in the right locations, it reduces their energy efficiency and causes inconsistent temperatures. For your family to enjoy a comfortable home throughout the year, you need to properly integrate your heating and cooling system into your new home design. To get help with your updated HVAC design, consult with an experienced HVAC team before you begin your next HVAC system installation.

2. Choosing the Wrong HVAC System Size

Another one of the most common HVAC mistakes during renovations is to pick an HVAC system that is the wrong size. For example, many people add an extra bedroom, guest room, or office during their renovations. Because this increases the square footage of your home, you’ll likely need to invest in a larger HVAC system.

If you don’t get a new HVAC unit, your HVAC system will have to work harder to reach the correct temperature. This can lead to inefficient energy usage, inconsistent cooling, and frequent repairs. Because the system is working harder than it normally would be, it will wear down faster and need to be replaced years earlier.

You also need to avoid getting an HVAC system that is too large. If the unit is oversized, it will short cycle and experience extra wear.

To determine your HVAC unit’s size, the HVAC technician will use a basic formula. First, they will start by measuring the basic square footage of your home.

For a basic calculator, this figure is multiplied by 25. Afterward, 400 should be added for every individual who will be living in that space.

Finally, you need to count the number of windows in the space. For each window, you should add 1,000 to the total. Once all of these figures are added together, you will have a basic calculation for your new HVAC capacity.

3. Ignoring Ductwork Design and Placement

Your ductwork is responsible for carrying conditioned air throughout your home. If the ductwork is poorly designed, leaky, or put in the wrong location, it can lower your home’s energy efficiency.

When designing your renovations, think about your home’s insulation and the pathway your airflow takes. For example, you don’t want furniture to block your vents. Additionally, duct leaks can end up costing you a significant amount of money on your power bill. According to ENERGY STAR, duct leaks can decrease your heating and cooling efficiency by 20%. To avoid hot and cold spots, airflow problems, and high energy bills, think carefully about your ductwork placement.

4. Not Upgrading Insulation at the Same Time

Another one of the top home renovation HVAC tips is to upgrade your insulation when you’re updating your home. Your home’s insulation is responsible for keeping heat in during the wintertime. During summer, it prevents heat from entering your home.

If you have poor insulation, your HVAC system must work much harder to reach the same temperature. Because of this, you should install the right insulation in your walls, ceilings, and flooring when you renovate your home.

By just insulating your crawlspace, basement, and attic, you can save 15% on your heating and cooling costs. To maximize these savings, you should also seal any gaps or cracks in your home’s walls.

5. Skipping Professional HVAC Maintenance After Renovations

Through fast AC maintenance services, you can prepare your home for summertime. Ideally, you should get a professional maintenance inspection twice a year. Your AC inspection should occur in springtime before you need to use your AC. Then, you should get an additional inspection in the fall so that your heater is ready for the winter.

After you complete your renovation project, you should schedule an additional maintenance inspection. A professional HVAC technician can help you determine if there are any post-renovation repairs or updates you need to make. The technician can also tell you if your HVAC system has the right capacity for your updated home.

Once the inspection is complete, there are a few additional things you can do to keep your home functioning at its best. For instance, you can reach out to an experienced HVAC company, so that your HVAC system can perform at its best throughout the year.

  • Clean Filters: Depending on the manufacturer’s instructions, you should change or clean your air filter every 30 to 90 days.

  • Remove Debris: Plants, debris, and other obstructions should be removed around your outdoor unit. If plants and debris are allowed in this space, it can clog your air conditioner and prevent it from working properly. Eventually, this can lead to additional wear and tear.

  • Check for Duct Leaks: Sometimes, gaps, cracks, and holes can appear in your ducts. If your energy bill is unusual, you should get your ducts inspected for potential leaks. You may also notice a lack of airflow from certain vents if there is a duct leak.

  • Get Rid of Obstructions: Move any furniture or other belongings that could be blocking your vents.

  • Clean Vents: Periodically, remove and clean the vents with warm, soapy water. Let them dry completely before you put them back on.

  • Test the Thermostat: Periodically, you should test the thermostat to make sure it is working effectively. This can be done by using a regular thermometer to double-check the thermostat’s readings. Additionally, you should make sure the thermostat turns on and off when you change the temperature setting.

Avoid Common HVAC Mistakes During Your Next Renovation Project

Fortunately, the most common HVAC mistakes during renovations can be avoided by planning ahead. Before your next renovation project, think about your home’s ventilation, ductwork design, HVAC capacity, maintenance plan, and insulation. With advanced planning and the help of an experienced HVAC contractor, you can avoid expensive mistakes and enjoy a more energy-efficient home.
