Signs Your Longmont Home Has a Humidity Problem

High humidity might seem minor at first glance, but it can lead to some sneaky issues that deserve our attention!

Here are a few signs to watch for:

  • A continual musty smell lurking in your basement or closets.
  • Condensation on windows or those humid rooms that just don’t feel cozy.
  • The unwelcome appearance of mold or mildew on walls, ceilings, or near windows.
  • Warping wood floors, sticky doors, or peeling paint that signals moisture trouble.
  • Stuffy air that can aggravate indoor allergies.

A great & easy solution is to invest in a humidity meter, which you can find for under $50. This device will help you monitor your indoor humidity levels, and the U.S. Environmental Protection Agency recommends keeping them below 60 percent, ideally between 30 and 50 percent. If levels are too high, consider a dehumidifier.

Also, if your home feels clammy while the AC is running, it may need to be checked to ensure it’s effectively reducing moisture.

Taking these steps will improve your indoor air quality and comfort. Let’s create healthier, more inviting homes with SAC Mechanical Heating & Air Conditioning.

Our Dehumidifier Services in Longmont

Whole-House Dehumidifier Installation

We start by checking the humidity in your home and where the moisture is coming from. Then we choose a unit with the right capacity, measured in pints of water removed per day, connect it to your ductwork and drain, and set the humidistat so you never have to think about it again.

We install trusted brands, including AprilAire, RGF, and Lennox, and we walk you through your options before any work begins.

Dehumidifier Repair & Service

If your dehumidifier runs constantly but the air still feels damp, stops removing water, leaks, or starts making new noises, call us. We diagnose the problem, explain what we found, and repair it, or tell you if replacement makes more sense.

We service whole-house dehumidifiers, including units we did not install.

Maintenance & Replacement

A yearly checkup keeps your system pulling moisture efficiently. We check the drain line and controls, clean as needed, and confirm the humidistat reads accurately.

When a unit is past repair, we help you replace it with a properly sized new one. Ask whether your dehumidifier can be added to one of our maintenance plans.

What Our Customers Are Saying

Frequently Asked Questions About Whole-Home Dehumidifiers

The right size depends on your home’s square footage, how damp it gets, and where the moisture comes from. Dehumidifier capacity is measured in pints of water removed per day, and a damp basement needs more than a dry upper floor.

Our technicians measure the humidity in your home and choose a properly sized unit.

Yes, a dehumidifier can alleviate allergy symptoms by reducing the moisture that promotes the growth of allergens like mold and dust mites. This creates a healthier, more comfortable living space for you and your family.

Dehumidifiers reduce excess moisture in the air, which can prevent the growth of mold, mildew, and dust mites. Maintaining optimal humidity levels improves air quality, creating a healthier living environment.

It can help. Mold needs moisture, and a dehumidifier lowers the humidity that allows it to grow. It will not fix a leak or remove mold that is already there, so fix any water source first and have the existing mold properly cleaned.

The cost depends on your home’s size, the unit’s capacity and brand, and how easily it connects to your ductwork and drain.

We give you a clear estimate before any work begins, and financing options are available for larger installations. Call (303) 825-9483 to get started.

Yes, Some do. Colorado’s dry climate means many homes need a humidifier in winter, but basements, crawl spaces, leaks, and stormwater seepage can still leave parts of a home damp.

A humidity meter reading above 60 percent is a good sign to call.
