What Your Neighbors Are Saying About Us
I recently had the pleasure of having Jay from BCI Mechanical service on our air conditioning unit, and I cannot recommend him highly enough. From start to finish, Jay was professional, punctual, and extremely knowledgeable.
Jeff was fantastic. He went the extra mile that the warranty company plumbers did not want to go, and he was able to identify that I had a blockage as opposed to the under-foundation pipe break the other company diagnosed.
I recently had a great experience with Zack. He cleared a blocked line and was efficient and professional. Zack arrived right on time, explained the issue clearly, at a very reasonable price. The work was completed quickly.
They were both very pleasant, honest, polite and respectful of our property. They went above and beyond and even drove from Denton to another warehouse to get a part so that we didn’t have to wait until Monday.
We’ve worked with BCI to replace our duct work and insulation, replumb our kitchen, and replace a leaking gas line. They have always been the most competitively priced, and their technicians were always professional and knowledgeable.
BCI is the best! I use them for AC and plumbing. Service is always excellent. They are like family! Never any creepy technicians and phone staff are kind and professional.
I could not ask for a better, more helpful person to arrive at my door to take care of my problem. The problem was solved and Jeff took care of two other issues. Plus he spent time to give me advice about replacing a sink.
Jay was an excellent technician! He answered all my questions, was courteous, professional and extremely helpful. I called for service and they came in two days. Going forward, I will continue using BCI and will recommend them to friends and family.
Noah and Josh were efficient in cleaning my ducts after tile renovation. They cleaned up the fine particles of dust that was left behind by the contractors. Noah and Josh went right to work upon coming in the house and completed the job in no time.
What Humidity Levels Should Be in Your Home
Keeping your indoor humidity within the right range makes a bigger difference than most people realize. The general recommendation is to keep indoor relative humidity between 30 and 50 percent. Staying within that range helps your home feel more comfortable, protects your belongings, and keeps your air healthier overall.
In Denton, outdoor humidity regularly climbs well above that range during the summer months, which means your home’s indoor humidity can creep up even with the air conditioner running. Your AC does remove some moisture from the air as it cools, but it’s not designed to handle dehumidification on its own. That’s where a dedicated whole home dehumidifier fills the gap.
How to Tell if Your Home Has Too Much Moisture
Excess humidity in a home tends to make itself known in a few different ways. Some signs are easy to spot, while others show up gradually over time. Here’s what to look for:
- You notice condensation forming on your windows, mirrors, or other cool surfaces.
- Your home feels sticky or clammy even when the air conditioner is running.
- You smell a musty odor in certain rooms or throughout the house.
- You see visible mold or mildew growth on walls, ceilings, or in bathrooms.
- Your wood floors, trim, or furniture are warping or swelling.
- Wallpaper is peeling or paint is bubbling in areas of your home.
- Family members are experiencing more allergy symptoms or respiratory irritation than usual.
If any of these sound familiar, your home’s moisture levels are likely higher than they should be. Denton’s climate makes this a common problem, and it’s one that tends to get worse the longer it goes unaddressed.
What Excess Humidity Can Do to Your Home
High indoor humidity isn’t just uncomfortable; it can cause real damage to your home and affect the health of the people living in it. Here’s a closer look at what too much moisture can lead to:
- Mold and mildew growth, which can spread through walls and surfaces and become a serious health concern for anyone with allergies or asthma.
- Structural damage to wood framing, flooring, and cabinetry as repeated moisture exposure causes warping, swelling, and rot over time.
- Damage to furniture, electronics, artwork, and other belongings that are sensitive to moisture.
- Increased wear on your HVAC system, which has to work harder to maintain comfortable temperatures when humidity levels are high.
- Pest problems, since many insects are drawn to damp environments inside the home.
- Worsened indoor air quality that can aggravate respiratory conditions and make your home feel less comfortable overall.
Getting a Whole Home Dehumidifier Installed
Installing a whole home dehumidifier is a job that requires proper sizing, placement, and integration with your existing HVAC system. Getting those details right is what separates a system that performs well from one that falls short of expectations. Here’s how we handle it at BCI Plumbing Heating and Air:
- We assess your home’s square footage, current humidity levels, and HVAC setup to determine the right size and type of unit for your needs.
- We install the dehumidifier in line with your existing ductwork so it treats air throughout the whole house.
- We connect the unit to a proper drain so condensation is removed automatically without any maintenance on your part.
- We set up and calibrate the humidistat so the system responds accurately to your home’s moisture levels.
- We walk you through how the system works and what to expect once it’s up and running.
We also provide repair services for existing whole home dehumidifiers. If your current unit isn’t keeping up or has stopped working altogether, our technicians can diagnose the problem and get it back in working order.
How a Whole Home Dehumidifier Actually Works
A whole home dehumidifier is installed directly into your existing HVAC system and works alongside it to manage moisture levels throughout your entire home. Here's the basic process: Warm, humid air from your home is pulled into the dehumidifier and passed over a set of cold coils. The moisture in the air condenses on those coils and drains away, and the drier air is then reheated slightly and returned to your living spaces. The system is controlled by a humidistat, which monitors your indoor humidity level and activates the dehumidifier when moisture climbs above your set threshold. Unlike a portable dehumidifier that only handles one room at a time and requires you to empty a water tank regularly, a whole home unit runs automatically and treats every room in the house. It's a much more practical solution for a home in a climate like Denton's.

Frequently Asked Questions
How is a whole home dehumidifier different from a portable one?
A whole home dehumidifier is integrated into your HVAC system and treats air throughout the entire house automatically. A portable unit only covers one room at a time and requires manual emptying. For a home in Denton’s climate, a whole home unit is a much more effective long-term solution.
What size dehumidifier does my home need?
Sizing depends on your home’s square footage, layout, and how much moisture you’re dealing with. Our team will evaluate your specific situation and recommend the right unit rather than guessing.
Will a whole home dehumidifier increase my energy bills?
Modern whole home dehumidifiers are designed to be energy efficient. In many cases, reducing excess humidity actually helps your air conditioner run more efficiently, which can offset the cost of running the dehumidifier.
How often does a whole home dehumidifier need to be serviced?
We recommend having it inspected as part of your annual HVAC maintenance. Keeping the coils clean and making sure the drain line is clear helps the system run efficiently and last longer.
Can high humidity really affect my health?
Yes. Excess indoor moisture encourages mold growth and dust mite activity, both of which are common triggers for allergies and asthma. Keeping humidity in the recommended range helps maintain healthier indoor air, which matters especially during Denton’s long, humid summers.
