Is it time to replace your heating and cooling? You may be on the fence about products if it's time or how much you want to spend. But something else is more important than all of these factors. The most important thing when choosing your HVAC is the size of the air conditioning and furnace. 

Is there a rule of thumb to select the best unit possible? How many BTUs do you really need? Many experts in the industry have their own idea of how much you may or may not need. For example, Trane suggests that the best rule of thumb is,” The maximum size unit you should buy would be 15% over the BTUs you need for cooling and 40% of the BTUs for heating. The max for heat pumps is 25% since it handles both cooling and heating.” when purchasing a new HVAC system. Let's take a look at a few more factors to consider.

Initial Cost

Of course, the cost will be a factor for most individuals. hvac companies, do you know this fact when they review available products with you? It is likely that they will break down pricing or how much you have available to spend on a new HVAC unit before anything moves forward. Getting the initial cost out of the way, you can start comparing brands. Not every brand is created equal, and they will have their own price points. Industry-leading products like Honeywell and Trane may be more expensive.

Operating Cost

You also need to consider the operating cost of your HVAC system. Getting the proper size will lower your operating cost. But why? If your HVAC isn't having to work as hard, it won't cost as much to run. That is why we recommend that you get a proper unit to meet your needs. Technicians will look at how many people are in your home and how big of square footage you have to determine the proper equipment needed to maintain comfort.

Space Issues

Sometimes space can be an issue. Air conditioning systems have two parts when you choose a central system. One outside and one inside. Some things can be manipulated, such as a rooftop AC, but this isn't always possible depending on your location, city ordinances, HOAs, etc.

Final Thoughts

Don't run out and buy just any air conditioner. We also don't recommend simply buying one that has an energy star label thinking it will be enough to cool or heat your home. Instead, work with a professional to get a well-fitting AC and heating system.
