1 | Should I Have My HVAC Regularly Inspected?

At the very least, you should schedule general HVAC maintenance once a year. Regular inspections help prevent significant problems in the future and catch repairs early. That way, you spend less on emergency visits from the HVAC experts.

However, to best care for your HVAC system, you should book an inspection twice a year- once before summer arrives and again when winter is on its way. The technician will check for damages, wear and tear, and other potential hazards, like mold growth. Plus, they’ll prepare your system for a season of heating or cooling, depending on the time of year.

2 | How Important is Indoor Humidity?

Humidity is crucial to your health and comfort indoors, as well as the functioning of your HVAC system. Which leads us to another frequently asked HVAC question- What humidity level should your thermostat show for the best possible indoor environment?

Ideally, the humidity level inside your home should fall between 30% and 50%. The level will likely increase during the summer due to higher humidity outdoors. And in the winter, the opposite is true.

Excessive humidity can make your house feel sticky and warm. And unfortunately, it can create the perfect environment for allergens, mold, and mildew to flourish. These contaminants are detrimental to the health of those dwelling in the home.

On the other hand, when humidity levels are lower than the ideal range, you may feel uncomfortably dry and frigid. You can experience chapped lips, itchy skin, and respiratory irritation due to a lack of moisture in the air.

3 | Can I Save Money by Adjusting My Thermostat?

If you don’t mind compromising your optimal indoor temperature to save some cash, you can adjust your thermostat to allow your HVAC to work a little less hard. This can be done by setting the temperature closer to the outside temperature.

This may sound unrealistic living in Florida. However, you don’t have to set the thermostat to 90 degrees in the summer. In fact, the experts recommend adjusting the setting by just six degrees to make a difference in your utility bills.

For instance, you’ll want to raise the temperature six degrees over your preferred setting in the summer. Likewise, during winter, you can drop the setting by six degrees.

You can also save money by adjusting the indoor temperature for when you sleep or leave the house for an extended period.

4 | When Do I Need to Replace My Air Filter?

Some of the most common HVAC questions are about air filters. Particularly often, technicians are asked about when the air filter should be replaced. The answer to this question will depend on a couple of varying factors. However, an excellent rule to follow is to replace the air filter every 30 days.

You can determine if your filter needs to be switched out by inspecting its appearance. If the filter looks dirty, discolored, or clogged with debris, it’s a good time to replace it.

Keep in mind that the season and what you do indoors will impact how often you’ll need a new air filter. During the winter and summer, we use our HVACs more. Thus the filter will need to be replaced more. In contrast, autumn and spring allow for less replacement.

And finally, burning candles, owning pets, or even dusting less also plays a role in how quickly the filter becomes dirty. Taking all the above into consideration will help determine how often your HVAC’s filter will be switched out.

5 | Do I Need to Clean the Air Ducts?

The air ducts throughout your home may contain pollen, bacteria, mold, dust mites, pet fur, and a slew of other contaminants. So, clearly, your ducts will need to be regularly cleaned by professionals.

This is one of the HVAC questions that people may ask but not take seriously as they should. The contaminants found in air ducts can cause illness and irritation for those inside the home. For this reason, it is essential to prioritize this step in caring for your HVAC system.

And even if you are confident that your ducts are free of these dangerous allergens, scheduling regular maintenance will reduce the amount of dusting you need to do and help the system run efficiently.

6 | How Do I Know What Size Filter My HVAC Needs?

Each HVAC unit requires a certain size filter to operate properly. To discover what size your system needs, take the following steps:

  1. Locate the frame where the air filter is placed.
  2. Remove the current filter, if necessary.
  3. Look for the size printed on the frame.
  4. Identify the size by searching for three numbers. For example: 14 x 18 x 1.

After determining what size you need, you can find the filter at your local hardware store.

7 | Why Does My HVAC Keep Freezing Up?

During the hot and humid summer months, it is common for an HVAC to freeze. This irony will often throw homeowners off.

How could the system freeze while surrounded by all this heat?

That’s why out of all the HVAC questions our technicians receive every day, this one comes up the most in the summer season. Luckily, this issue has two likely causes that can easily be identified:

The coils are clogged: Clear the debris and dust from your coils to allow for better airflow. Moisture will settle on the coils if the airflow is blocked by debris, covering the unit with ice in minutes.

The refrigerant is leaking: Leaks can happen when refrigerant lines take on wear and tear. This results in low internal pressure that will cause your unit to freeze.

8 | How Does an HVAC Cool a Home?

The technical operation of an HVAC system involves advanced science. It can be challenging to understand without experience or the right education. That’s what makes this one of the most difficult HVAC questions to answer in simple terms.

Though, the general idea is that the unit absorbs heat energy and releases it outside. Then, the inside air is replaced with better-quality and cooler air.

9 | What Size HVAC Do I Need?

We want to say that this matter is as straightforward as a larger home needing a bigger HVAC system. However, the size you will need depends on other factors, like:

  • How well insulated your home is.
  • The placement and size of the windows in your house.
  • The design of your home.

In most cases, an energy auditor is required to determine what size HVAC your home needs.

10 | How Can I Make My HVAC Last Longer?

There are plenty of things you can do to prolong the lifespan of your HVAC system. To start, regular maintenance by a trusted HVAC company will keep your unit running as long as possible.

Other excellent habits to adopt when caring for your home’s HVAC include:

  • Clearing the unit of debris often.
  • Not overworking the unit by setting the temperature too high or too low, depending on the season.
  • Replacing the filter with a new one each month.
  • Keep the area surrounding your HVAC dust and debris-free.
