Does an AC Do Enough to Control Indoor Humidity?

Monday, August 22nd, 2022

The answer to the question in the title depends on how much humidity your home deals with during the summer. If you don’t normally experience extremely high indoor humidity (relative humidity higher than 70%, although some people find more than 60% uncomfortable), then your AC will be able to keep you cool and happy. The air conditioner is not exactly controlling the humidity—although it’s doing some dehumidification—but it doesn’t have to work hard against humidity to deliver a comfortable environment for your house.

If high humidity is a problem you often encounter during warm weather, then it’s unlikely your AC can do much about it. It can provide cooling, but it won’t make a noticeable effect on humidity because an air conditioning system isn’t equipped to do that job.

Why Air Filters Often Need Pairing With Air Purifiers

If you’re looking to have cleaner air in your house—and more people are concerned about this than ever before—you have several options. Most people usually think of having special whole-house air filters installed. These filters need professionals to plumb them into the ductwork (the filter that’s already in place on the HVAC system isn’t for air cleaning purposes). Filters are an excellent method for improving indoor air quality, and most homes can benefit from them. 

However, air filters sometimes need the assistance of air purifiers. The right air filtration and air purification system combination can remove more than 98% of unwanted particles from the air circulating through a home. Let’s look into more of the details about when air filters need the help of air purifiers.

The Difference Between a Whole-Home Air Filter and an HVAC Air Filter

Monday, May 2nd, 2022

If you looked at the title of this post and thought, “Wait, aren’t those the same thing?”, then we recommend you read further. Homeowners are often confused about their options when it comes to getting air filters and air purifiers to improve their household indoor air quality. It often starts with mistaking the job of the standard filter that’s part of the HVAC system—also called the “furnace filter” or “AC filter” (one filter usually does both jobs.)

There’s an important difference between what we call a whole-home air filter and the filter located on the HVAC cabinet or behind the return air duct in the house.

Monday, March 7th, 2022

At this moment, you might have a sneaky thief crawling about your home, maybe in the attic, maybe hiding in the walls. This thief won’t carry off your most valuable possessions, but it will lift money from your pocket bit by bit so that it can add up to hundreds of dollars over a year. This thief can even cause other damage to your house without you knowing about it at first.

You don’t need to call the police to catch this thief. To stop this pickpocket, you’ll need an HVAC expert! Because this thief is actually the ductwork of your home: the air channels carrying heated and cooled air throughout the rooms. When air ducts start to spring leaks, it will take money from you on your utility bills, month after month until you have professional duct service in Hatboro, PA.

Winter Is Tough for Healthy Indoor Air, But We Can Help

There are two times during the year when the indoor air quality inside a home can take a steep plunge. The first is the beginning of spring, which is prime time for allergies. The second is during the coldest period of winter. 

What makes winter so difficult? Because in order for a home to stay comfortable and not allow all the heat inside to escape outside, the doors and windows must stay shut. This prevents fresh air circulation through the house that removes dry and pollutant-filled air. 

The good news is that this isn’t a hopeless situation. If you want to enjoy better indoor air quality in your house this season, our team at Dowd Mechanical can help you with several special HVAC services. Below are some of the ways we can help you enjoy a better life indoors this winter.

It’s a good question, and to get a solid answer, you’ll need to have professionals assist you. Some homes don’t need special air purifiers, while others will benefit immensely.

4 Great Benefits of Whole-House Dehumidification

Monday, July 12th, 2021

Humidity. The word itself usually conjures up thoughts of sweating through hot days. Humidity on its own isn’t necessarily bad—extreme dry air can also create problems. But when the relative humidity of the air rises above 60%, the amount of moisture in the air can lead to many issues.

But you have an air conditioner in your house, so that should take care of the humidity, right? We have some bad news there:  a central air conditioning system can help keep your house cool, even on humid days, but it isn’t actually a dehumidifier. It does remove some moisture from the air as it runs (which is why you hear dripping water from its cabinet), but not enough to make a difference. If you want balanced humidity for your home, you’ll need to have professionals install a whole-house dehumidifier. 

There are four major benefits of having whole-house dehumidification:
