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

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.

Frequent Breakdowns
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.

How to Know If You Have A Heat Pump

Posted on August 15, 2024 | by arketing | Leave a Comment

When it comes to home heating and cooling, understanding what kind of HVAC system you have is crucial.

Among the various systems available, heat pumps are becoming popular in the U.S for their efficiency and versatility.

However, many homeowners aren’t sure if their system includes a heat pump or a more traditional furnace and air conditioner setup.

So, here’s how to know if you have a heat pump.

Heat Pump Exterior Unit — An Example of an Exterior Heat Pump Unit

Check the Exterior Unit

The easiest way to determine if you have a heat pump is to inspect the outdoor unit of your HVAC system. If your home uses a heat pump, the exterior unit will look almost identical to a standard air conditioner.

However, there are a few key differences:

Labeling: Look for labels or markings on the unit that say “Heat Pump,” “HP,” or mention heating functions. Some manufacturers explicitly label their units as heat pumps.

Mitsubishi Heat Pump Label — Look for stickers like this on your exterior unit. It will tell you if it’s a heat pump system

Brand and Model Number: If the unit isn’t clearly labeled, jot down the brand and model number and search online or refer to the user manual. The manufacturer’s website can confirm if the unit is a heat pump.

Ecobee Heat Pump Wi-Fi Thermostat — This Ecobee Wi-fi Thermostat is designed for Heat Pump Systems

Thermostat Settings

Your thermostat can also provide clues about whether you have a heat pump system. Modern thermostats are usually designed to work with various HVAC systems, including heat pumps. Look for the following:

“Heat” and “Cool” Modes: If your thermostat has separate settings for “Heat” and “Cool,” this isn’t necessarily conclusive, as both heat pumps and conventional systems have these. However, a heat pump will often have an additional setting labeled “Emergency Heat” or “Auxiliary Heat.” This setting activates the backup electric resistance heating, which is unique to heat pump systems.

Operation Behavior: During winter, switch your thermostat to heating mode. Then, go outside and check the exterior unit. If the unit is running while your home is heating, you likely have a heat pump. In contrast, a traditional system would use the indoor furnace to provide heat, with the exterior unit only running during the cooling season.

Observe the Unit’s Behavior Throughout the Year

A heat pump operates year-round, providing both heating and cooling. If you notice that your exterior unit is active in both summer and winter, it’s a strong indicator that you have a heat pump. On the other hand, if the outdoor unit only operates during the summer months and remains dormant in winter, it’s likely that you have a conventional air conditioning system paired with a separate heating system, such as a gas furnace.

Inspect Your Utility Bills

Heat pumps tend to use electricity for heating rather than natural gas or oil. If your heating bill is mostly electric and you don’t have a separate electric furnace, this could suggest you have a heat pump. Keep in mind that heat pumps are generally more energy-efficient than traditional electric heating systems, which might result in lower heating costs during milder winter months.

Our knowledgeable Comfort Advisors are experts at making your home more energy efficient. We partner with the Mass Save program to ensure you can get the best rebates possible on high-efficiency systems.

Pay attention to your utility bills. High Electrical bills may be from operating the heat pump

Just Call Landry!

If you’re still uncertain, it’s always a good idea to contact an HVAC professional. Our HVAC experts at Landry Mechanical will inspect your system, confirm whether you have a heat pump, and provide advice on maintaining or upgrading your system for optimal efficiency and comfort.

Knowing whether your home is equipped with a heat pump can help you make informed decisions about energy use, maintenance, and potential upgrades. By checking the exterior unit, thermostat settings, and your system’s behavior, you can quickly determine if you have a heat pump. If in doubt, “Just Call Landry” and our skilled technicians will bring comfort to your home.

How to Winterize Your Air Conditioner

Posted on August 6, 2024 | by arketing | Leave a Comment

How to Winterize Your Air Conditioner

HVAC Exterior Condenser covered in snow — Snow build up can cause rust to form on HVAC units. Leading to expensive repairs.

Hard to believe that Summer is almost over. The fun, warm summer days will soon give way to autumn colors and cooler temperatures.

That means it’s time to winterize your A/C system so that it works properly next summer.

If you don’t it could lead to expensive repairs that could de-rail next summer’s plans.

Why Winterize?

Winters in New England are often cold, long, and feature harsh conditions like blizzards. This weather can lead to corrosion inside your unit or damage from falling ice or tree limbs.

Small animals like Squirrels, Mice, and Chipmunks may also make your A/C unit their home if it’s not properly covered.

What Steps Should I Take Before Winter?

Listen To Your Compressor

Run your A/C system as you do normally.

Notice any grinding or unusual noises?

Noisy A/C Unit — Notice any unusual sounds coming from your A/C units? Time for a repair!

Probably time to “Just Call Landry” because you’ll need our expert Air Conditioning Repair services.

Change Your Air Filter

Change your air filter at the end of each cooling season. If you’ve ran your A/C this summer the filter is probably dirty from pollen and other allergens. A new filter protects system components and ensures acceptable indoor air quality.

Are you looking for a new filter for your A/C?

Check out our online store to order the filter directly to your home.

Cover The Unit

New England winters can cause snow to build up on the unit.

This build up can cause many problems with the unit come next spring.

In addition, small rodents often invade A/C units and make nests inside.

Properly Covered HVAC Exterior Unit — Properly Covering Your Exterior HVAC Units saves $ and increases lifespan of the system

Use a specially designed A/C cover that fits over the unit.

The fit shouldn’t be too loose or too tight as the unit will need some room for ventilation.

You may also use a tarp and bungie cords as seen in the photo above.

Call The Experts

If you are unable or confused about winterizing your A/C Landry Mechanical is here to help. Our home Cooling Experts are ready to assist you.

We offer a variety of Air Conditioning services including repairs, general maintenance, installations, and replacements.

What Does My Air Filter Actually Do?

Posted on September 4, 2023 | by Landry Mechanical Inc Plumbing HVAC & Electric

This is a great question, and one that could clear up a lot of misconceptions with our customers when it’s answered correctly. While yes, the air filter does positively impact your indoor air quality, that’s not its intended function. The air filter that fits in your air conditioner or heater’s return air duct is designed to keep things clean for the system itself, for a few reasons we’ll get to.

Changing the air filter on a regular basis has some huge benefits that you can take advantage of as well. For instance, you’ll see better energy efficiency, comfort, and a longer-lasting system if you change the filter every 1-3 months.

But when it comes to air conditioning in Middlesex County, you’ll want to know why you’re changing this component so frequently before you actually put it on your schedule. Let us help you with that down below.
