AC Sizing in Mount Pleasant, WI: How to Pick the Right Unit
4.8 Google Rated
Getting a new AC is a juggling act between choosing features, price, and installation schedules. You may be surprised to find that the size can make or break the final decision.
The wrong size can cause a snowball of issues like short cycling, worn-out parts, and higher energy bills. Thankfully, once you learn about important ratings like BTU and SEER2, you can finally narrow down the best size for your home or room.
At Southport, we want you to understand your investment inside and out. We’ll explain AC sizing in Mount Pleasant, WI, and why this detail matters so much for your home.
Why Does Size Matter for Cooling Systems? 4 Main Benefits
Size is easily one of the most overlooked details for choosing the correct AC size in WI. While you should definitely consider features like variable speed settings or smart thermostats, these benefits should bump size to the top of the list.
1. Reduce Frustrating Short Cycling
The wrong size will leave you frustrated in no time. Short cycling is a common issue with cooling systems that are far too small, leading them to turn off before your home cools down. It constantly turns off because it thinks it’s doing the job right, but for a different house.
When you have the right size, your AC will emit just the right amount of cooling. If you’ve gotten the appropriate size before and still noticed problems with cycling, you may have other airflow problems in the home that need attention (like leaky ductwork).
2. Cool Your Home Faster
Have you ever waited hours for your home to cool down? We’ve looked at AC cooling times in other parts of Wisconsin, and it’s a pain point you can reduce with the right size.
An appropriately sized cooling system will start to noticeably cool things down within several minutes. At most, larger homes may need a half hour to an hour.
It’s important to keep in mind that airborne moisture traps heat and makes your home feel warmer than it actually is. If you notice your cooling system usually works well on dry days, but seems to take forever on muggy days, the humidity may be to blame.
3. Extend Your System’s Lifespan
Short cycling takes a toll on your cooling system since turning it on uses up significant energy. Leaving your system on for a long time to make up for weak cooling also wears it out faster.
Can you already see where we’re going with this? A poorly sized cooling system that constantly cycles or has to be turned on repeatedly is going to have a much shorter lifespan. Appropriate AC or HVAC sizing in Mount Pleasant, WI, can potentially add a few years onto your purchase with no extra effort on your part.
4. Trim Your Energy Bills
Leaving an incompatible air conditioner on for longer will finally cool your home down, but you’ll spend a lot more money in the process. The right AC sizing in Mount Pleasant, WI, is key for ensuring your energy bills don’t balloon out of control.
When AC maintenance isn’t giving you the performance you need, a new installation may finally give you a break. Your first order of business when choosing the right size is learning your way around common cooling system ratings.
BTU and SEER2: The Main Ratings for Choosing Your AC’s Size
While any manufacturer can tell you that their cooling system is right for your home, rating systems back these claims up. The main ones you need to be concerned with are BTU and SEER2.
BTU Measures Cooling Capacity
BTU is short for ‘British thermal unit’, referring to your main fuel’s heat content and how well your system can cool down your home per hour. However, you’ll also see BTU measured in tons, referring to how much your system weighs.
A single ton will measure roughly 12,000 BTUs. For example, if you have an air conditioning system that weighs two tons, it will have a BTU of around 24,000. However, AC sizing in Mount Pleasant also needs to look at SEER2 ratings to give you a fuller picture.
SEER2 Measures Energy Efficiency
While SEER2 ratings can seem similar to BTUs at a glance, they focus on measuring peak performance during a given season. Since cooling systems are mostly used in spring and summer, they let you know if your system is providing a fair trade of performance and energy usage.
Cooling systems made today will have a SEER2 rating hovering between 14 and 16, which is considered standard for most homes. However, you may want a rating in the 18 to 20 range if you want the best mix of long-term savings and performance.
A system that works for a one-story, single-bedroom home won’t do well for a multi-story house. Now that you know how BTU and SEER2 work for your home, you need to start calculating your house size with the Manual J Method.
What Is the Manual J Method?
A good rule-of-thumb for calculating the best size is to take your room’s square footage and multiply it by the standard BTU range. However, this calculation still doesn’t take into account details like your home’s ductwork or even its sun exposure. This one-size-fits-all problem is where Manual J comes in.
Skilled technicians use this industry-standard calculation that helps narrow down the ideal size. It takes into account small, yet significant details like window square footage, insulation, ceiling height, and local climate to make sure your system can handle any season.
