HVAC installation is not as simple as mounting a TV to the wall and seeing if it will turn on. Even if you get the best unit in the right size, many other mistakes in the installation process may lead to a variety of problems. This is why it’s important to find the right installation contractor for the job who has the skills and experience to engineer and design the perfect AC system for your home.
Here are some common mistakes that can occur with improper AC installations. Each point will explain what HVAC problems are associated with improper installation:
1 – Poor Ductwork Design
Your HVAC unit only does half the job. The rest of the process goes through ductwork. The ductwork design is crucial to distribute the treated air evenly and thoroughly.
Ductwork is a crucial part of any HVAC system as it is responsible for distributing conditioned air throughout the home. That said, it is important to ensure that it is properly designed and installed to avoid any issues.
Here are some common mistakes when building ductwork:
- Incorrect size
One of the most common mistakes in ductwork is using the wrong size. This often happens when homeowners try to save on costs by using smaller diameter ducts. However, using smaller ducts will only lead to problems down the line as it will restrict airflow and cause your HVAC system to work harder. This will not only lead to higher energy bills but will also shorten the lifespan of your HVAC system.
- Terrible placements of vents
When it comes to ductwork another common mistake is poor vent placement. Vents should be placed in strategic locations to ensure that conditioned air is evenly distributed throughout the home. However, many homeowners make the mistake of putting vents in hidden or hard-to-reach areas, making it difficult for the air to circulate correctly.
- Inefficient routes
Yet another common mistake when designing ductwork is taking inefficient routes. This often happens when homeowners try to save on costs by using shorter or smaller pipes. However, using smaller pipes will only lead to problems down the line as it will restrict airflow and cause your HVAC system to work harder. This will not only lead to higher energy bills but will also shorten the lifespan of your HVAC system.
- Not sealing the ducts
One of the essential aspects of ductwork is making sure that it is properly sealed.
- Poorly insulated ductwork
Another common mistake when it comes to ductwork is not correctly insulating it. This can lead to higher energy bills, drafts, and condensation. Make sure to have your ductwork adequately insulated to avoid these issues.
Ductwork is a crucial part of any HVAC system, but it is important to ensure that it is properly designed and installed to avoid any issues. If you are having trouble with your ductwork or think it may be inefficient, make sure to contact a professional for help.
2 – Bad-Quality Sealing of Ductwork
A ductwork leak is one of the most common HVAC problems associated with improper installation. Unfortunately, many irresponsible technicians use improper tapes or similar products to seal the duct connections. Improper tape may work, but only temporarily.
Eventually, it will wear off and expose the gap between ducts. The leaks may also cause humidity problems that lead to mold infestation. You can avoid such issues by using the proper sealant product for the ductwork installation.
One of the most common sealant products used in ductwork installation is mastic. Mastic is a pliable, tar-like substance that can be spread over the joints between pieces of ductwork. It dries quickly and forms a tight seal lasting many years.
Another popular sealant product is fiberglass tape. Fiberglass tape is coated with an adhesive that bonds it to the ductwork. As a result, it forms a strong seal that won’t break down over time.
Either of these products can be used to seal duct connections and prevent leaks.
3 – Wrong Choice of Condenser Placement
Your condenser unit requires space to dissipate the heat without any problems. Give it at least two feet of clearance on each side. Placing it near obstacles may cause the machine to overheat and break more easily.
4 – Wrong Choice of Thermostat Placement
Indeed, even this small device requires thoughtful placement to ensure your system runs optimally. For example, the sensor won’t work well if placed nearby vents or heat-generating electronics. Sun exposure may also affect its performance.
As a result, your system might produce too much cooling and inadequate heating. If possible, place your thermostat in the middle of the most commonly used room on the property. That way, it can accurately gauge the temperature, and your HVAC system will function more efficiently.
If you need to place the device near a window, shade it from direct sunlight to maintain optimal performance. You should also avoid placing it too close to doors or vents since that might skew the readings. Ultimately, you want the sensor to be in an area that best represents the space as a whole.
5 – Loose Parts
Mistakes as little as not tightening the parts well can lead to problems. For example, your system might make noises when operating due to the clanking between parts. This problem may cause wear and tear sooner if the loose parts are crucial.
Many people understand how crucial it is to buy a suitable HVAC unit and choose the right size. But unfortunately, many people still fail to realize how important it is to install it properly.
DIY installation may do more harm than good unless you have the proper skill, knowledge, and license. However, hiring unlicensed technicians is also just as dangerous. Not only will they likely make mistakes, but they will also not take any responsibility if you encounter any HVAC problems associated with improper installation. Therefore, you need a seasoned HVAC service company with the experience to avoid these issues.
