Is Excess Humidity Causing Problems in Your Home?

Condensation on Windows and Walls

Water droplets forming on windows, mirrors, or walls (especially in the morning) signal indoor humidity levels that are too high and need to be controlled before damage occurs.

Musty Odors That Won't Go Away

A persistent musty or damp smell in your home, basement, or crawlspace indicates excess moisture feeding mold and mildew growth that air fresheners can’t solve.

Visible Mold or Mildew Growth

Mold spots on walls, ceilings, bathrooms, or around HVAC vents are a direct result of uncontrolled humidity, and a serious health concern for your family.

Home Feels Sticky and Uncomfortable Even with AC Running

If your air conditioning is running but the air still feels heavy, clammy, and uncomfortable, your AC alone can’t remove enough moisture. A dedicated dehumidifier is needed.

Complete Dehumidifier Installation Services in Birmingham

Birmingham’s hot, humid summers, valley-trapped moisture, and frequent spring and summer thunderstorms can create persistent humidity problems inside your home, and the area’s many older houses with dated ductwork often struggle to keep that moisture under control. At One Hour Heating & Air Conditioning, our licensed and experienced indoor air quality professionals specialize in diagnosing and solving whole-home humidity issues for homeowners throughout Birmingham, Mountain Brook, Homewood, Vestavia Hills, and Hoover.

Whole-Home Dehumidifier Installation

A whole-home dehumidifier is the most effective way to control excess moisture throughout your entire home. Installed directly into your HVAC system’s ductwork or alongside the air handler, these systems automatically remove excess moisture from all circulating air before it reaches your living spaces. Residential systems are typically sized between 70 and 130+ pints of moisture removal per day, and we install leading brands including Aprilaire, Santa Fe, Ultra-Aire, Honeywell, and Lennox.

Whole-Home Dehumidifier Services:

Crawlspace & Basement Dehumidification

Crawlspaces and basements are often the largest sources of excess moisture, as ground moisture, poor ventilation, foundation seepage, and missing vapor barriers can create ideal conditions for humidity buildup beneath your living area. Because moisture naturally rises, a damp crawlspace can affect your entire home’s air quality, humidity levels, and structural integrity.

Crawlspace & Basement Services:

Humidity Assessment & System Sizing

Every humidity problem is different, and our assessment process includes testing humidity levels throughout your home, identifying moisture sources, evaluating crawlspaces, attics, and other problem areas, reviewing ventilation performance, and inspecting HVAC operation. The goal is to maintain indoor humidity between 30% and 50% year-round while identifying air leaks, duct issues, or ventilation deficiencies that should be addressed for optimal results.

Dehumidifier Installation FAQs for Birmingham Homeowners

How much does whole-home dehumidifier installation cost?

The cost of a dehumidifier installation depends on several factors, including the type of system (whole-home HVAC-integrated, standalone, crawlspace, or basement), the capacity needed for your home, and any additional work such as ductwork modifications, condensate drain routing, electrical upgrades, vapor barriers, or crawlspace encapsulation. We provide an in-home humidity assessment and upfront, transparent pricing before any work begins, so you know exactly what to expect with no surprises.

What size dehumidifier do I need for my home?

Homes with moderate humidity concerns often require systems rated between 70 and 90 pints per day, while larger homes or homes experiencing significant moisture intrusion may require capacities of 90 to 130+ pints per day.

Is a whole-home dehumidifier better than portable units?

Yes, whole-home dehumidifiers provide significantly greater effectiveness, efficiency, and convenience than portable units. Instead of treating a single room, they automatically control humidity throughout the entire home using your existing HVAC distribution system.

What humidity level should my home be?

Most indoor air quality experts, including recommendations from the EPA and ASHRAE, suggest maintaining indoor relative humidity between 30% and 50% year-round. Humidity above 50% creates favorable conditions for mold growth, dust mites, musty odors, respiratory irritation, and reduced indoor comfort.

How long does dehumidifier installation take?

A standard whole-home HVAC-integrated dehumidifier installation typically takes four to eight hours, standalone basement dehumidifier installations are often completed within three to six hours, and crawlspace dehumidification projects involving encapsulation coordination or moisture remediation may require one to two days. Additional time may be needed for ductwork modifications, condensate drain routing, electrical upgrades, or crawlspace preparation.

Do you offer warranties and maintenance plans on dehumidifier installations?

Yes, labor warranties for professional installations typically range from 1 to 2 years, depending on the project. Equipment warranties are provided by the manufacturer and commonly offer five to six years of parts coverage, with some premium brands including extended compressor protection.

When to Replace or Repair an Air Conditioner in Birmingham: 4 Top Signs

Most air conditioning units will last an average of 12 years but this is based on how well you maintain it and whether you get regular air conditioner repairs when something starts to go wrong. Thankfully, your air conditioner will give you signs that you might need Birmingham, AL AC installation on a new model, beyond just age.

Age

Age is of course the biggest indicator that you need to replace your air conditioner with a new AC installation from our license technicians rather than make a repair. Energy Star recommends replacing your air conditioner every ten years before things break down completely. So, if you just bought a new home in Birmingham, ask the previous owner when the last air conditioner was installed and whether or not they did maintenance at any point. It’s not uncommon for homeowners to neglect AC maintenance and only call technicians when something goes wrong and if that’s the case in your home, you might need to consider a replacement and new air conditioner installation sooner rather than later.

Condition

No matter the age, you can look at the condition of your current air conditioner and get a feel for how degraded it might be. For example, if you look at the AC unit under your porch and it is buried halfway up with debris and fallen leaves, surrounded by broken pieces of old garden pots and garbage, chances are it hasn’t been maintained and it’s not in great condition. You can save yourself significantly on energy bills as summers continue to increase by investing in a new Birmingham, AL AC installation.

Bills

Take some time to monitor your energy bills. If you have noticed your energy bills continue to rise but you aren’t using your air conditioner with increased frequency, it might be a sign that your unit is breaking down and needs to be replaced. In most cases, if you multiply the cost of a given air conditioner repair by the age of the unit and it’s more than $5,000, it’s going to be a better investment for you long-term to have a new air conditioner installed.

Repairs

Finally, if you are regularly calling our team or someone else to conduct repairs, that’s an indicator that your air conditioner is on its last legs and instead of trying to patch it regularly with minor repairs or even major repairs, talk to our team about installing a new air conditioner.

Choosing the Right AC System for Your Birmingham Home

At One Hour, our local technicians in Birmingham, AL can help install several types of air conditioners. If you aren’t sure which type of air conditioner you need or want, we can discuss the pros and cons of several options and then schedule your installation once you’ve made a decision.

Central Air Conditioners

The most common is called central AC. Central air conditioners usually have a furnace and an air conditioner or a furnace and a heat pump. They can also have an air handler and a heat pump. The combination means you have one unit to provide cool air in the summer and another to provide hot air in the winter. Each of these combinations requires ductwork so if you already have ductwork in your home, you can simply replace an existing central air conditioning unit or make a modification to something a bit more substantial. However, if you don’t have duct work and you have an older home, this might require some costly remodels.

Ductless Mini Split Systems

A ductless mini split system is an alternative to central air if you don’t have ductwork in your home and don’t want to install it. These units can be mounted to your wall or your ceiling.

Window/Wall Units

If these are too advanced or you want something that is smaller and can be used for single rooms or floors, we can help you install window units and wall units to improve your energy efficiency and maximize your space.

Let Us Help You Decide

When you contact our team for your initial consultation, we can help you decide which system would work best.

Size of Your Space

The size of your home is a big factor. You want to make sure that the system you have is large enough to support your cooling needs otherwise it will cycle on and off too frequently which is not only wasteful but can cause the motor to break much earlier.

Energy Efficiency

If energy efficiency is important you can look for those units with Seasonal Energy Efficiency Ratio (SEER) ratings.

Budget Considerations

Some models with those energy efficiency ratings might be higher costs up front but they can give you reduced energy consumption long-term. This is something you’ll have to weigh against the upfront costs.

Smart Technology Integration

If smart technology integration is important to you you can find systems that have things like home automation or smartphone integration. Contact us today to schedule a consultation.

Note, you don’t have to wait for your current air conditioner to completely break down before you invest in a new one.
