If you are a home or business owner, you may have questions regarding your HVAC system and how you can help it to function more efficiently. There are a lot of misconceptions when it comes to these units and how they work, but one of the most common myths is that closing doors and vents will help to improve the efficiency of your HVAC system. While it’s true that this might result in some energy savings, there are many other steps you should take to optimize your home or business’ HVAC efficiency before you start closing doors and vents.
First, this article will discuss what an HVAC system is and how they work before diving into a list of suggestions for how you can improve the efficiency of your HVAC system.
What is an HVAC System?
HVAC systems work by taking in cool air from outside and bringing it indoors, where it is then circulated throughout the indoor spaces within your home or business through vents and registers. The unit will also expel warm air back outside after it has been conditioned to make your home or business comfortable. This means that there are always some areas inside that may be either cooler or warmer than other parts of the building due to an HVAC system’s constant circulation.
Closing doors and vents or sealing them in any way is a common practice that some people will use to try and make their HVAC system work more efficiently. However, many homeowners and business owners do not realize how much their HVAC system affects their energy usage. This causes them to choose not to readjust some aspects of their daily routines that could help to increase the system’s efficiency.
While your HVAC unit will likely take in slightly cooler air from outside if you close doors and vents in an attempt to improve the efficiency of your system, this action cannot actually do much when it comes to helping you save money on energy costs throughout the year. That being said, there are still steps that you can take to optimize your unit’s efficiency-here are a few ideas:
- When using your programmable thermostat, ensure that it is set according to local weather patterns. For example, during warmer periods, you will likely want to change the settings on your thermostat so that it does not take in as much cool air from outside. This can help minimize how often your HVAC system has to work, translating into energy savings over time.
- Ensure that the filters throughout your home or business are clean and free of obstructions. Depending on the type of filter you use, this could be anything from once a month to once every few months, but you must check them regularly regardless of whether you have pets or allergies. This may be a good idea to ensure every three months as a general rule of thumb.
- Keeping vents clear throughout your home or business can also help ensure that it operates more efficiently. While some vents may only need to be cleared out every few months, others may require more attention. If you have a commercial HVAC system that you use within your business, hiring a professional commercial HVAC company to inspect and maintain your units annually can help ensure they run efficiently without any obstructions in the vents throughout your building.
- In addition to taking steps towards ensuring that your doors and registers remain clear, make sure that you check for any leaks within the air ducts or around the unit itself when it is running. Check the outside of your home or business and the inside for evidence of water damage from condensation. If there are any leaks, this could significantly impact how much your HVAC system needs to work to keep indoor humidity levels at a comfortable and healthy level.
One final note: if you feel like your HVAC system is not working the way it did when it was brand new, contact a service professional for an inspection. This may be something that would be best done during warmer months so an expert can take a look without requiring extra work on your unit. Suppose there actually are any noticeable issues with your unit, such as leaks within the ducts or an unusually loud noise when it turns on. In that case, you should have these repaired right away by either calling a professional or simply purchasing the parts and having someone come out.
Other Common HVAC Questions and Answers:
Q: Should I close the vents in my home when I am gone to save energy?
A: Closing registers and vents is not always the best way to save energy. While opening windows or using fans may be slightly more efficient, it won’t provide you with many benefits over time. Instead, make sure to program your thermostat for times when you are away from home, re-arrange how furniture is set up within rooms of your house that get used most often (to allow better airflow), use ceiling fans whenever possible, etc. The goal should be to keep your HVAC system running for as little time as necessary-this can help you save money on energy costs without requiring much extra work on your end!
Q: What is an HVAC tune-up, and why do I need one?
A: An HVAC tune-up, also known as a maintenance check, can help extend the lifespan of your unit. You must hire a qualified professional to come out and inspect your system during different times of the year (especially if you have allergies or pets that you would like to keep safe from dust and other irritants) so they can clean all filters and vents/ducts throughout your home or business. This will ensure that air is flowing effectively and your equipment runs more efficiently at all times-if there are any issues, these will be caught during the tuning-up process.
Q: How often should I change my filter?
A: Most residential and commercial HVAC systems need to have their filters changed every one to three months, depending on the type of filter you use. If it appears dirty or dusty after this time frame has passed, it is likely time for a change! If you have pets or allergies, your filter may need to be checked more frequently.
Q: How often should I clean my air ducts?
A: Unless you notice any issues with your unit (e.g., leaking within the ducts), there is no set time frame for how often you must clean them. It should only take a professional about an hour or so to inspect and vacuum throughout your system; if there are any significant leaks, they will need to be repaired during this time.
