How to Cool Down a Brick House in Summer

How to Cool Down a Brick House in the Summer

Homeowners often wonder how to keep walls cool in summer, as heated exterior walls can make a home uncomfortable and cause an HVAC system to work harder. Bricks present a particularly big challenge. They’re extremely good at absorbing heat, so keeping your home cool may be more difficult unless other measures are taken. If so, then warmer bricks can serve as a barrier that contains cool air in your home.

To cool things down if your brick house is too warm, you can:

Protect Your House from Direct Sunlight

The greater the heat exposure, the more heat bricks will absorb. You can limit direct sunlight by using trees and other greenery for shade. Planting around windows is beneficial as it limits the amount of sunlight that enters your home. Sun reflective window film can also be an option for some.

Install Blinds/Awnings

Windows don’t really insulate against heat (unless you purchase replacements, such as double-pane windows, that are more insulating). Blinds and shades are effective for blocking sunlight. Covering your windows can help keep your home cool during the day. You can also place awnings over the windows where you’re getting direct sunlight. They can add charm to your exterior décor as well.

Also, don’t keep your windows open during the day. Opening them at night, however, can enable you to benefit from lower temperatures. You can also save energy by relying less on the AC.

Insulate Your Home

Insulation prevents a buildup of heat that bricks radiate into the building. The options aren’t limited to insulating foam in walls, around edges, and corners. If your home doesn’t have framing, install it behind brick walls, which allows you to place insulating materials such as fiberglass. On the inside, install drywall to seal the insulation between it and the framing, so the temperature remains lower inside on a hot day.

Seal Any Points of Air Leakage

Cracks around windows and doors are a major source of hot air entry. Any air that’s cooled in your home can escape as well. Seal any cracks by repairing window or door frames, adding caulking or filler, or installing weatherstripping.

Use Reflective Paint/Materials

Painting bricks a lighter color, like white, light green, or powder blue, allows them to reflect heat from sunlight instead of absorbing it. There are insulating paint additives that can help as well. Sun-reflecting materials can be installed on the roof, including metal and reflective coatings for shingles. Another option is to use clay bricks, which have a lower thermal mass than concrete; clay heats up faster, but also releases it quickly instead of continuously radiating it into your home.

Install Fans

A fan doesn’t actually cool the air in the room, but it can make you feel cooler and lower your body temperature. Fans also help reduce the demand on your air conditioner. When turned on, they make the apparent temperature seem lower, so you can set the thermostat a couple of degrees higher. This can make a big difference on your energy bill.

Install or Replace Your Air Conditioning Unit

Air conditioning is an investment, but today’s reliable, high-efficiency ACs can keep your brick home cool for many years if properly maintained. Running an air conditioner can help keep the temperature of bricks low to start. This means your home is cool starting early in the day. Bricks, combined with insulation, are very effective at holding in cold air.

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.

My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
