Home Dehumidifier Repair, Maintenance & Installation

Dust mites, mold, and mildew tend to enjoy higher humidity levels. Adding a whole-home dehumidifier to your home’s AC system can help reduce humidity levels by drawing excess moisture out of the air and permanently removing it. The addition of a dehumidifier will help protect your home and also lower energy costs, by helping your air conditioner run more efficiently. With heat and humidity, it is important to have a system in place that helps remove that excess moisture from your home. This is where Fenwick Home Services can help! At Fenwick, we offer whole home dehumidifier installation, maintenance, and repair services.

A whole-home dehumidifier can guarantee a balanced relative humidity level of 45%-55%. Improper humidity levels can cause additional problems such as follows:

  • Peeling paint/wallpaper
  • Dust mites
  • Warped flooring
  • Damaged furniture and art
  • Mold, mildew, and moisture
  • Worsened allergies and asthma
  • An infestation of pests and insects
  • Damaged electronics
  • Sticky windows and doors

With various types of home dehumidifiers available, the team at Fenwick home services highly recommends a whole-home dehumidifier system. Adding a dehumidifier both reduces and regulates the humidity in the air. Dehumidifiers can be used in single rooms. However, we recommend a whole-home dehumidifier to ensure you are able to maintain an optimal humidity level of 45%-55% in each area of your home.

Types of Dehumidifiers

  • Heat Pump Dehumidifier: This type of dehumidifier requires a fan, a heat pump, and heat exchange coils to remove excess moisture from the air. The fan receives the air which then passes through the heat exchange coils. These “heat” exchange coils in this type of whole house dehumidifier system are actually extremely cold. This allows moisture to condense and collect.
  • Dehumidifying Ventilator: The main component in a dehumidifying ventilator is the exhaust fan. The fan expels air outside, using a sensor. Dehumidifying ventilators are typically found in basements, attics, and crawl spaces.
  • Chemical Absorbent Dehumidifier: Commonly known as a desiccant dehumidifier. This home dehumidifier consists of hydrophilic materials, such as silica gel, instead of condensation, on the coils to remove humidity.
  • Homemade Dehumidifier: While we don’t recommend building your own dehumidifier, it is possible. Although possible, it should not be permanent. Homemade dehumidifiers can be made using charcoal, road salt, or de-icing salt.

Why is My Dehumidifier Not Collecting Water?


Humidity tends to form in environments with a temperature above 65 degrees. If your home dehumidifier is no longer pulling water from the air, and the temperature is above 65 degrees, the unit’s compressor may not be running. The compressor is a pump that circulates the refrigerant through the evaporator to extract moisture from the air.

The compressor circuit located in the capacitor is in place to help the compressor’s motor to start. If the capacitor has failed to start or if the overload device continues to trip, you might have a faulty capacitor. Schedule your appointment with Fenwick Home Services to ensure an accurate diagnosis.


If the compressor doesn’t run, you can test the overload. A common cause for failure of the overload is from operating the dehumidifier with an extension cord that is either too long or too short.

Fan Motor

In order to have a properly functioning whole home dehumidifier, there needs to be an adequate amount of air blowing across the evaporator coils. Air blowing across the evaporator coils prevents frost or ice buildup. Once you can identify little to no air coming through the grille, you can determine the filter is clean.

Removing the cover, check the fan area and inspect the coils to look for any restricted areas. The fan motor should rotate freely and be clear of any lint or dirt. With caution, you can observe the fan motor, paying attention to any humming noises. If the motor or fan is rotating slowly it might be considered defective and needs to be replaced.

Electronic Control Board or PCB Assembly

Modern home dehumidifiers are equipped with an electronic control board. The PCB is used to control the compressor and fan motor. The control board is fully furnished with sensors connected to the individual parts. If the PCB is not running properly, a skilled technician at Fenwick can run a diagnostics test to better understand the problem.
