"Great company! We had used another company that our home warranty company sent us to but after 2 visits, they still couldn't figure out what was wrong. Mainline came out and had the issue figured out in no time. They ordered the part, fixed it, & no more issues! We were incredibly happy. From the lady who makes the appointments…

Frequently Asked Questions About Home Dehumidifiers

Alabama’s climate produces high humidity for much of the year, which can make homes feel sticky and uncomfortable. A whole-home dehumidifier lowers moisture levels, reducing mold risks, improving comfort, and helping your AC run more efficiently. For many homeowners, a dehumidifier is a must-have solution for year-round comfort.

Look for these common signs:

  • Condensation on windows or glass doors
  • Musty odors, especially in basements or crawlspaces
  • Mold or mildew spots on walls or ceilings
  • Sticky or damp indoor air
  • Higher energy bills due to AC overuse

If you notice these issues, a whole-home dehumidifier can provide relief.

Unlike portable units, a whole-home dehumidifier is connected to your HVAC system. As air passes through, the system removes excess moisture before distributing it back into your living spaces. This creates even humidity levels throughout your entire home, improving comfort and protecting against moisture-related damage.

In many cases, yes. Common issues include clogged filters, electrical problems, or drain line blockages. Our technicians inspect your system, identify the problem, and recommend the best solution. If repair is possible, we get it running again quickly. If not, we discuss replacement options that suit your needs and budget.

Most whole-home dehumidifiers last between 8 and 12 years, depending on usage and maintenance. Regular filter changes and inspections extend their lifespan. If your unit is older, frequently breaking down, or no longer controlling humidity effectively, replacement may be the best option. Our team helps you decide what’s right for your home.
