How Summer Weather Affects Your Indoor Air Quality

Posted on July 17, 2025 | by arketing | Leave a Comment

Summers in Central & Eastern Mass can be very hot and humid. Many homeowners spend most of their time outdoors during the summer months. However, when they step inside, they often find their indoor air quality is very poor. Allergens, higher humidity and rising temperatures all contribute to reduced air quality. Landry Mechanical put together this guide on How Summer Weather Affects Your Indoor Air Quality and how to improve it.

The Summer Heat

Pollutants inside your home are exacerbated by warmer temperatures.

If you use A/C in your home, you most likely have the windows and doors closed to keep cold air in.

These allergens linger inside your home and mix with warm air to create an uncomfortable environment.

The Danger of Humidity

Humidity isn’t just uncomfortable; it can become a breeding ground for harmful air pollutants. If indoor humidity rises above 60%, mold, mildew, and dust mites will thrive inside of your home.

Here are some tips to reduce your home’s humidity:

Consider a humidity monitor to keep levels between 30-50%
Properly Vent Bathrooms, Kitchens & other High Moisture Areas
Use portable dehumidifiers or consider installing a whole-home dehumidifier
Clean and dry damp areas and spots quickly

The Danger of Allergens

Pollen from trees, weeds, and other plants ends up everywhere during the summer including your home!

Pollen can enter your home on clothes, pets, and open windows. This contributes to poor indoor air quality during the summer season. It can also trigger symptoms in people with asthma, allergies, or other respiratory issues.

Here are some tips to reduce allergens in your home:

Monitor pollen counts on weather apps
Keep windows closed during days with high pollen counts
Run an air purifier with a HEPA filter
Regularly clean your home with microfiber cloths and vacuum cleaners

Air Conditioning & Air Quality

Air conditioning keeps you comfortable on steamy summer days.

However, A/C systems can either improve or degrade your home’s air quality. Dirty A/C filters can spread dust, pollen, and mold throughout your home. Malfunctioning A/C systems can also increase humidity.

Here are some tips on how to use your A/C without reducing air quality:

Clean or replace your air conditioning filter regularly
Let fresh air inside your home on a regular basis during cooler weather
Consider upgrading your A/C system to a newer model with humidity control
Use an air purifier in addition to your A/C in your home to filter out other allergens

These beverages increase your chance of dehydration. Make sure you have bottled water available before the next heatwave strikes

Check Your A/C System

When Should I Repair or Replace My AC?

Spring is finally here! Many homeowners wonder when should I repair or replace my AC?

Landry Mechanical is here to offer expert advice on when you should consider repairing or replacing your AC.

How Long Do Air Conditioners Last?

According to Carrier, you can expect a good 15 to 20 years of cooling from a new high-efficiency air conditioning system.

However, there are a number of factors that impact how long air conditioners last.

Climate (Especially High Humidity)
Air Quality Issues such as pollution or salty sea air
Regular or Irregular AC Maintenance
Installation Quality & Proper Sizing
How Often The System is Used

Signs Your Air Conditioner Isn’t Working

There are many tell-tale signs that your air conditioner isn’t working. Here are some of the most common signs we run into at Landry Mechanical.

Water or Refrigerant Leaks
Thermostat Problems
Unit Won’t Turn Off or Turn On
Poor Airflow/Uneven Cooling
Burning or Moldy Smell Coming From Unit
Excessive Noise Coming From The Unit
Excessive Dust Accumulation
Hot Air Blows Out Of The Unit

AC Refrigerant Leaks Small & Large — If You Notice Bubbles like these you have a refrigerant leak

If you notice these signs it’s best to “Just Call Landry” Our Air Conditioning Experts frequently repair and replace Air Conditioning Systems in Central and Eastern Massachusetts.

When Should I Repair My AC?

New Central Air Conditioners can be an expensive investment.

Therefore, if your existing unit isn’t running properly it might be a good idea to consider repairs before replacements.

You Have A Newer Air Conditioner

If you have a newer air conditioner that’s less than five years old, it would be best to repair it. Many Air Conditioners come with a warranty that may cover repair costs.

You Have a Small One-Time Repair Need

If your ac has newer and you experience a small one time repair need it’s not a sign that you’ll need a replacement.

However, if you notice repeated breakdowns, it’s time to “Just Call Landry” and we’ll replace your AC system.

When Should I Replace My AC?

When it is no longer feasible to repair your AC it’s time to consider replacing it.

Here are some of the best reasons to replace your AC.

You Want To Lower Your Energy Bill

Older AC systems are not as energy efficient as newer models.

One of the best ways to reduce your energy cost is to replace old AC systems with new more efficient models.

However, this must be balanced with the cost of the new system.

Your Old AC Unit Is Rusty Or Ugly

If your old AC unit has signs of rust, corrosion, or is just ugly it’s time to replace the unit. Repair will not be an option in this case.

Your Air Conditioner is Too Small

Not All AC Units are equally powerful. Some AC systems are great for one room, but are unable to cool an entire house efficiently.

Also, underpowered AC units can raise your energy costs and shorten the unit’s lifespan by running it constantly.

Your AC System is Mismatched

In a central air system you have indoor units and outdoor units.

These components need to be compatible in order to cool your home effectively.

If you have a mismatched AC system, it won’t run smoothly and is far more likely to break down.

Conclusion

No homeowner wants their Air Conditioner to break down in the hot summer heat.

Fortunately, Landry Mechanical is here to help!

Our Air Conditioning Experts will keep you cool this summer with repairs and replacements when you need us.
