Importance of Size in HVAC

When it comes to getting a new HVAC system, most households are unaware that having the largest air conditioning or heating equipment is not always the greatest option. If you search for HVAC contractors near me, you will get the required help in selecting the optimum size to achieve maximum comfort.

If the HVAC System is Too Small

  1. The system will most likely cool or heat some areas of a home while leaving others uncooled or unheated. 
  2. An undersized system will continue to run and consume more power, resulting in skyrocketing energy bills. 
  3. The unit’s lifespan will be shortened as a result of the frequent short cycling.

If the HVAC System is Too Large

  1. Large systems tend to start, attain temperature quickly, and then shut down. 
  2. By installing the right size system rather than an oversized one, you’ll be happy in the long term.
  3. Be ready to get an oversized electric bill.

Criteria to Measure Correct Size

BTUs, Tonnage, and SEER ratings are the three criteria that determine the size of an air conditioner. You can take professional help like furnace installation near me to make a better decision. Let’s have a look at each one.

  • BTU 

It’s crucial to understand what BTUs are and why they’re essential. Because the variables in a home vary so considerably from house to house, no one can agree on how many BTUs are required for a room.

BTUs are determined not only by the size of the space but also by the number of levels in a house, the openness of the plan, the height of the ceiling, the number of windows in the room, and other factors. All of these factors influence the amount of energy needed to accurately chill a room.

Why Are BTUs Important?

Rather than attempting to calculate the BTUs yourself, you should get your air conditioner correctly sized by a licensed HVAC contractor by looking up the air conditioning installation near me. Otherwise, it will either never meet demand or will be overly intense, producing repeated stops/starts and causing damage to your system. 

  • Tonnage of A/C

BTUs and Tonnage are inextricably linked. They are reliant on each other. A tonne of air conditioning produces around 12,000 BTUs. Whereas BTUs refer to the rate at which water is heated, tonnage refers to the amount of energy necessary to melt a tonne of ice in 24 hours. 

  • SEER 

The SEER rating is the final factor in determining an ACs power and efficiency. Your ACs SEER rating does not imply that it will blow colder air than usual.

Faulty Sounds from your A/C

Sometimes the smallest things that go unnoticed might be the most important tell-tale sign that something is not right. In the case of your A/C, it is the sounds it makes. It is one of the easiest ways to catch the problem early and prevent any further damage to your HVAC system. Professional help is just a ‘find an air conditioning installation near me’ search away! But first, you need to know what these sounds mean.

And with this article, we try to help you understand what your A/C is trying to convey with sounds so that you can make an early call and save yourself from paying extremely high electric bills! 

  • Banging

This sound can indicate a problem with the compressor of your A/C. The compressor distributes refrigerant throughout the HVAC system by removing the hot air from the room where the A/C is installed. The banging sound may indicate the loosening of compressor parts that end up colliding with the external metallic frame of the compressor. In case of any metallic sounds, there might be parts of your A/C that need replacement. Either way, this is not a fix-it-yourself job and might require professional AC repair in Alvin, TX for better assistance. 

  • Screeching 

The refrigerant that is circulated throughout the HVAC helps carry away the heat from the room, while a motor blower fan is provided within the indoor A/C unit to help distribute the cooled air in the room. The squealing or screeching is a sign that either this blower fan is malfunctioning or that the motor of the fan, installed as the outdoor unit, might be damaged. If the bearings of these fan motors are damaged, even then a screeching sound can be heard.

  • Buzzing or Humming 

Usually, these sounds are characteristic of an electrical issue that needs immediate attention. The problem can be due to a short-circuit in the contactor relay switch. Apart from this, the reason can be mechanical – dysfunctional fan blades, loose condenser coils, or even a problem with the copper lines. When you hear a buzz or a hum, it’s better to contact a professional, especially an electrician, so that the risk of the short growing into an electrical fire can be minimized.  

  • Bubbling 

This sound might translate to a problem with the pipes – either a block, a hole, or crack in the drainage pipe or severe damage to the pipe that carries the coolant or refrigerant leading to a refrigerant leak. This problem reduces the efficiency of the HVAC system and consumes a lot of energy which will get reflected in your monthly electricity bill. 

These are some of the most common noises that are noticed generally with HVAC systems. If you hear these or any other concerning noises, it’s time to start looking for HVAC contractors near me or you can also contact us at (713)-875-0980 or write to us at We provide a lot of services related to HVAC systems, for which you can browse through our website
