8 HVAC system myths that are a burden on your pocket

8 HVAC System myths

HVAC systems are one of the most convenient heating and cooling systems that have revolutionized the world. Heating Ventilation and Air Conditioning, as the name implies, is a system specifically designed both for heating and cooling. Hence, with HVAC, you do not need to buy separate AC and a heater for different summer and winter, respectively.

Moreover, there are numerous benefits of an Heating and Air system. However, there are some common myths related to an HVAC system, which are a burden on your pocket. Today, we will discuss those 8 myths and debunk them.

Top Heating and Air system myths that are a burden on your pocket

Below-specified are the 8 HVAC myths that are a burden on your pocket.

1. Regulating the thermostat will save you money.

One of the most popular myths that we are sure everyone has heard in their lifetime is that lowering or raising the temperature by varying the thermostat would save you money.

. A lot of people believe that lowering their thermostat settings would make their room cool faster. Plus, many people believe that increasing their thermostat value would make their room warmer in a short period.

. But to tell you the truth, it is not the case at all. Increasing or decreasing the temperature does not affect the operating principle of an HVAC system.

. Instead, the system takes the same amount of time to cool or warm your room or house irrespective of temperature.

However, the thing, which you probably do not know is that adjusting the temperature of your HVAC system closer to the outside temperature reduces the electricity bill. And help you save a few extra bucks.

2. Big HVAC systems perform better.

Another myth is that getting a big HVAC system would enhance the heating and cooling process and is, in general efficient. So, it is cost-effective. However, it is not the case. The truth is that if the Heating and Air system is too large or too small, its compressor would frequently turn on and off. It is known as short cycling.

Short-cycling puts too much pressure on the compressor of an HVAC system and reduces its lifespan. All this increases your maintenance and repair costs. Moreover, short cycling is also havoc on your utility bills.

3. Turning off the HVAC system on hot summer days when not at home will save energy.

Another popular myth that many believe in is that turning off their HVAC system on hot summer days before leaving their home reduce power consumption.

However, it is not the case. Doing this does the opposite of it. It is because when you turn off your HVAC system, its compressor boots up when you start it again after coming back home. All this uses more power, which increases your electricity bill.

The simple solution is to increase the thermostat value by certain degrees instead of completely shutting it down.

4. Closing vents in vacant rooms reduces power consumption

Closing vents in empty rooms (where there are no people) can reduce the overall power consumption is a lie.

The reason is that as the HVAC system is designed to cool and warm the air, there is a significant amount of air pressure inside the ducts. This pressure is needed to be released, and closing the vents increases the air pressure and mess up air distribution.

The buildup pressure can cause the air ducts to get leaked. Hence, doing this is extremely dangerous and can significantly increase your repair bills.

5. You can place the thermostat anywhere in your home

A thermostat is a device that controls or adjusts the temperature according to after a certain temperature condition is met. However, the thermostat’s location greatly affects your electricity bills.

. It is because installing your thermostat near heat or cooling sources, such as near a window where rays of the sun can directly fall on the thermostat, can cause the readings of a thermostat to be messed up.

. All of this can cause the thermostat to work even when it should not be. All of this increases your electricity bills.

Moreover, high temperatures can even wear down your thermostat. And without a thermostat, your HVAC system is of no use. Hence, make sure to avoid this mistake.

6. Covering the outdoor unit of an HVAC system improves performance

Another myth is that covering the outdoor unit of an HVAC system, particularly during winter, improves performance. However, it is not the case. You should not ever cover the outdoor unit of an HVAC system as excessive moisture builds up due to restricted airflow.

Moisture causes wear down your HVAC unit and also causes mold infestation, which increases your repair cost. Moreover, mold can also damage your entire ductwork. The cost of replacing air ducts is not inexpensive as well.

7. Maintenance of the HVAC Heating system is not beneficial.

Every piece of equipment needs frequent maintenance. Otherwise, it would break down. Many people believe that HVAC systems do not require any maintenance and then suffer the consequences. Most of the HVAC systems get damaged due to a lack of maintenance and tuning.

Therefore, to avoid any problems, make sure to conduct a frequent checkup of your HVAC system. You can also contact an HVAC system professional for a checkup and tuning.

Moreover, frequent checkups would also allow you to figure out and solve any problem in the system. As  

a result, you could save your money from being spent on high repairing costs.

8. The AC compartment in an HVAC system is linked with the ceiling fan

Many people believe that the AC compartment integrated into their Heating and Air system would not use more power when they would turn their fans on.

The truth is that the ceiling fan only distributes the cool air throughout the room instead of cooling the air. Turning on the ceiling fan with your HVAC system would only increase your electricity bill.


The above-specified are the 8 most popular HVAC system myths that are a burden on your pocket. Solutions to the myths are also covered above. So, makes sure to follow them.
