Do You Live with a Hot Upstairs?

This is a common problem for a lot of large homes. The 2nd floor can never get properly cool in the summer. You may have to crank up the AC to get it to acceptable levels, meaning freezing out anyone on the first floor.

If you live in a 2-story house, you probably know this situation all too well. Here at Standard Plumbing, Heating & Air Conditioning, we have heard from many Manhattan homeowners who have been suffering with a hot upstairs.

There are a lot of old homes in Manhattan. Being the HVAC company that has serviced Manhattan homes for nearly a century, we have run across every type of heating and cooling problem. And fortunately, there are more solutions to achieve true home comfort in all rooms today than they were a hundred years ago. So even if we are dealing with a drafty old house, you do have options to make all floors on your home cool and comfortable this summer.

Potential Cooling Problems

  • Does your home have sufficient insulation? Many older ones do not. They can be so drafty that it’s virtually impossible to get consistent temperature control throughout the house.
  • Is your roof absorbing heat? Not only can a poorly insulated a roof cause a warmer upstairs, a roof made from materials that absorb heat could also play a role.
  • Did your home undergo an attic renovation? If so, that may be a part of the cooling problem. If proper adjustments were not made to your home’s heating & cooling system to accommodate this new living space, that could be affecting comfort levels in other parts of your home. A system that was originally designed for 1 floor will probably not give you comfortable temperature everywhere.

Understanding Why a 2nd Floor Gets So Hot

Hot air rises. Without utilizing any air conditioning system, your upstairs should always feel hotter because of this basic scientific fact. But even with central air or other HVAC system, some homes’ 2nd floors will still get hotter than the main level. After all, your single cooling system (with components usually located on the ground floor and basement) has to do more work to get that cool air all the way to your 2nd floor.

As you head into another hot Kansas summer, facing the dread of how uncomfortable it’s going to be on your 2nd floor, you may think you’re not left with a lot of options.

You may think your choices come down to either getting a larger, more energy-efficient air conditioner or just give up. You think there’s no real way to fix it, so you’ll just avoid spending time upstairs.

It’s your home. You deserve to be comfortable in all your rooms. There are solutions to having a hot upstairs!

When you have Standard help you finally solve your hot 2nd floor problem, the first thing we do is to determine the source of the problem.  Some of the issues we will look for include:

  • Could you have an issue with your duct work?
  • Do you need better insulation?
  • Is your AC unit the proper size to handle your home’s square footage?
  • Is your cooling system in proper working order?

When to Consider Getting 2 AC Units for a 2-Story House

Instead of replacing what may be a perfectly working air conditioner with a larger one to accommodate your 2nd floor, you should get an AC unit installed to specifically address cooling the 2nd floor.

There are a few things to consider when trying to decide if you need a second air conditioning system installed:

 

AC INSTALLATION COST

An additional unit may cost less than what you think. After all, this AC is not going to cool the entire square footage of your home. A 2nd AC unit that works to only cool your 2nd floor would be much smaller than one that would be needed to cool your entire home.

Standard, or any professional HVAC company, will be careful to calculate exactly what size AC unit your rooms upstairs need. The square footage of your 2nd floor will determine the proper unit size. Give us a call at Standard Plumbing Heating & Air Conditioning at (785) 776-5012 and we will be able to determine exactly what air conditioner would be best for your home.

 

ENERGY WASTE & BILLS

New installation isn’t the other money matter. How much do you spend on your energy bill each month? It might sound surprising but by having 2 air conditioners to cool a 2-story home may save you money.

If you’ve been dealing with a single AC system that wasn’t built to handle all your space, you are putting a great demand on your system. It’s working to put out more cool air than it was designed to do. If you are making your downstairs cooler than comfortable to make it right upstairs, then you probably already have realized you are wasting energy (and money). An additional air conditioner focused on cooling just the upstairs will take the work away from the other unit.

 

PEACE OF MIND

Having 2 air conditioning units provides you with some unique assurance. You may feel more secure in knowing that your chance of a summer HVAC disaster is greatly reduced. If one of your air conditioners were to break down, you will have another unit still operating. While this lone unit won’t be sufficient to cool your entire home, you will at least have some level of cooling in your home until an AC repair technician come out and fix the broken air conditioner.

 

2nd AC LOCATION

Finding where to put a second AC system can be a challenge. This includes the inside unit (the evaporator) and the outside AC unit (the condenser). You may have limited space for installing a second air conditioner. In addition, a 2nd unit will need ductwork that is separate from existing ducts with your current unit. Our technicians can walk you through your options to make sure the best space is used for this installation.
