What Size HVAC Unit Do I Need For My House?

An HVAC unit is an important component of your home, controlling the air and climate. It’s a big investment, and worth spending time and consideration on before making a decision. Part of selecting the perfect HVAC unit is by ensuring that you have the proper HVAC unit size for your home.

Read this article to find out some of the greatest benefits of having an HVAC unit installed, plus how to calculate what size of HVAC you need.

Benefits Of An HVAC Unit

Having an HVAC unit installed can offer a number of great benefits for your home. A few benefits include:

Energy Efficient

Rather than having your climate control systems in your home divided between air conditioning and heating, an HVAC is able to easily control both. Having both of these essential home features combined means savings on your energy bill, as well as space within your home.

Climate Control

An HVAC unit controls the temperature in your home, but it also controls the amount of humidity within your home. Having too much moisture in your home can cause mold and water damage issues in your home. An HVAC can help prevent this, saving you both time and money.

Improved Air Quality

Did you know that HVAC units can also aid in the quality of the air in your home? Having a quality HVAC unit ensures there is always clean, filtered air from indoors and out moving throughout your home. Having stagnant air in your home can cause health issues like allergies and respiratory issues, so having an HVAC can also help keep you feeling better.

HVAC Unit Size

Selecting the right unit size is critical to ensuring your unit works exactly as intended and lasts for a long time.

One of the best ways to figure out what size of HVAC unit you need is by using a professional HVAC calculator or HVAC formula. The very same calculators that HVAC professionals use are actually available online for anyone to check out. Making use of this great, practical tool can help you understand your home’s specific needs.

Other items to consider:

  • The size of your existing HVAC unit
  • Square footage of your home
  • Your climate zone
  • Insulation
  • BTUs (British Thermal Units)

Also, make sure you also do some basic internet searches for HVAC units, check out different models, and establish what your general budget is. Don’t hesitate to reach out to the friendly, local HVAC professionals in your area and speak with them about your needs. They’ll be able to help you figure out exactly what you need, suggest appropriate HVAC units, and provide you with an estimate for installation fees.

Basic HVAC systems include:

  • Portable heat pump systems
  • Ductless mini split
  • Hybrid split systems
  • Hydronic heat
  • Zoned HVAC equipment
  • Geothermal heat pumps
  • Electric furnace systems


Having an HVAC unit can offer a number of amazing perks to your home. It can help prevent water damage in your home, save you money on your utility bills, and even improve your air quality! To get all of these wonderful benefits, it is vital that you select the right size of HVAC for your home. Using a professional HVAC calculator and doing prior research before purchasing your unit can ensure you get the perfect HVAC.
