Choosing the right size HVAC unit for your Greenville, SC home can be a daunting task. Not only do you need to know what size unit you need, but you also need to consider other factors such as efficiency ratings, installation costs, and maintenance needs. This guide will walk you through the steps of finding the best-sized HVAC unit for your home so that it is comfortable all year round.

Calculating Square Footage

The first step in choosing an HVAC system is calculating the square footage of your home. The square footage of a space is typically determined by measuring the length and width of each room in feet and then multiplying them together for each individual room or area. To get an accurate estimate, make sure to measure multiple rooms if necessary and account for any areas with limited air flow, such as closets or attics. Once you have an estimate of your home’s total square footage, you can use this number when selecting a new HVAC system.

Choosing an Appropriate System Size

Once you have calculated your home’s total square footage, you can begin looking at different types of systems that are appropriate for your needs. Most HVAC systems come in sizes ranging from 1 ton (12,000 BTU/hr) up to 5 tons (60,000 BTU/hr). As a general rule of thumb, one ton should provide enough cooling capacity for 400-600 sq ft depending on ceiling height and insulation levels. It’s important to note that larger homes may require more than one system to ensure adequate cooling capacity throughout the entire house.

When it comes to choosing an HVAC system, there are two main types available – centralized and decentralized systems. Centralized systems are typically more expensive than decentralized ones, but they allow you to control the temperature in multiple rooms simultaneously with one central thermostat. Decentralized systems, on the other hand, usually consist of several individual units that are placed throughout the house and controlled separately from one another. Depending on the layout of your home and how much control you want over which rooms get heated or cooled, one type may be better suited for you than another. 

Maintenance and Efficiency Ratings

In addition to selecting the right size for your home or business, it is also important to consider efficiency ratings and maintenance requirements when selecting an HVAC system. Most newer models offer higher energy efficiency ratings than older models which could save money on utility bills over time. Additionally, it’s important to factor in annual maintenance costs into the overall cost of ownership since regular tune-ups will help keep the system running efficiently and extend its lifespan.

Weather Conditions & Usage 

Another factor to consider is the weather conditions in your area and how much you use your AC/heating system on a daily basis. If it gets very hot in the summer months and very cold in the winter months, then you will likely need a larger system than if temperatures stay relatively mild all year round. Additionally, if multiple people are using the same AC/heating unit on different schedules throughout the day (e.g., one person arrives home from work while another leaves for work), then this can also affect what size HVAC unit you need in order to keep up with demand. 

Choosing a new HVAC system can seem like a daunting task but with a little research and preparation it doesn’t have to be! Start by measuring your home’s square footage and using this number as a reference point when shopping around for different models and sizes. Make sure to consider energy efficiency ratings as well as annual maintenance costs before making your final selection so that you get the best value out of your investment! With these tips in mind, you should be able to find an appropriately sized HVAC unit that fits both your budget and heating/cooling needs!
