3 Things To Know Before Installing an HVAC Unit

May 12, 2025

Installing a new HVAC unit is a big step—it’s not just about staying cool in the summer and warm in the winter. It’s an investment in your comfort and your energy bills. Before you dive in, it helps to understand a few key points so you’re not caught off guard. Whether you're upgrading your system at home or looking into options for your business, here’s what you should know to make the best choice.


1. Choose the Right Size

First things first—size matters, and we’re not talking square footage alone. If your HVAC system is too large, it may cycle on and off frequently, causing wear and tear and jacking up your bills. Too small, and it won’t keep up on the hottest or coldest days. This is where commercial HVAC companies come in handy—they have the tools and expertise to run a proper load calculation based on your building’s insulation, layout, and even sun exposure. It’s worth the time to get this right.


2. Plan for the Full Cost

Installing a new unit isn’t cheap, and there’s more to the price tag than just the equipment. According to Bob Vila, the average life expectancy of an HVAC unit is between 12 to 15 years. That’s over a decade of repairs, tune-ups, and energy usage to consider. Before you sign off on anything, make sure you budget not just for the unit itself but also for regular maintenance and possible future repairs. Reputable commercial HVAC companies often offer maintenance packages, which can save you money (and headaches) down the road.


3. Prioritize Energy Efficiency

These days, it’s all about efficiency—both for your wallet and the environment. A higher SEER (Seasonal Energy Efficiency Ratio) rating generally means lower energy use and monthly bills. Plus, depending on where you live, you might qualify for rebates or tax credits just for choosing a high-efficiency system. Commercial HVAC companies can walk you through the options and help you find a unit that balances upfront cost with long-term savings.


Installing an HVAC unit doesn’t have to be overwhelming, as long as you’re informed and ask the right questions. From choosing the right size to prioritizing energy efficiency and verifying your installer, you'll be in a strong position to make a smart, long-lasting investment.
