Whole-Home Dehumidifier Services in Olympia, Washington

Humidity over the summer gets miserable. Given that Western Washington is on the coast, humidity levels often rise above what a single AC unit can handle, and a whole-home dehumidifier may be needed to bring your indoor humidity to a comfortable level. At Black Hills, we can assess your home and help you determine the best dehumidifier system for you.

Bring your indoor humidity back to a comfortable level with Black Hill’s whole-home dehumidifier installation, repair, and maintenance services in Olympia, Washington.

Expert Whole-Home Dehumidifier Installation Services

The first step to installing a new dehumidifier is a home assessment. We first want to be sure that your air conditioning unit is working properly, as it should be taking care of at least some of the humidity as a natural part of its cooling process. 

Our professional HVAC technicians will expertly install a new whole-home dehumidifying system with precision and quality workmanship. The system will be integrated with your existing HVAC system so that all air circulated through the air handler can be treated. 

We’ll ensure the system works correctly and that it is properly draining water to avoid pooling or molding.

Professional Dehumidifier Repair Services

Typically, problems with dehumidifiers are mainly centered around the motor, compressor, or refrigerant lines. If your dehumidifier is having problems, it likely can be repaired. Replacement parts can often be obtained from the original manufacturer with the right channels. 

Black Hill’s experienced technicians can work on any make or model of dehumidifier system. We offer expert whole-home dehumidifier repair services so that your system works efficiently. 

Reliable Dehumidifier Maintenance Services

Your whole-home dehumidifier system should be serviced on a yearly basis, just like your air conditioning unit. We’ll clean the system’s condenser coils, replace or clean its filter, and ensure there aren’t any leaks, electrical issues, or blocked ductways. 

Whether it’s a minor adjustment or a filter cleaning, you can count on our indoor air quality experts to perform whole-home dehumidifier system maintenance and tune-up services. 

Benefits of Whole-Home Dehumidifiers

Take advantage of the following benefits of a whole-home dehumidifier:

  • Enhanced Comfort: High humidity makes the air stuffy and uncomfortable, even if the temperature is moderate. Removing the excessive moisture from the air allows you to breathe easier, keep your skin from sticking to clothes, and generally make your living environment more comfortable. 
  • Better Indoor Air Quality: Too much moisture will lead to mold, mildew, and allergen growth. Mold and mildew put out spores in the air, and dust mites feed on the water as well. Eliminating excess moisture will cut down dramatically on these fungi and pests, making breathing easier. 
  • Protection of Your Property: Excessive humidity can cause mold and mildew to grow in your home, cause your wood furniture and home frame to expand and shift, and can also cause your paint to bubble up. Dehumidifiers help protect your home from mold, mildew, paint bubbling, and wood rot by removing moisture.

Real Comments From Real People

So Very Impressed

- Debbie F.

Diamond Harris was the HVAC Design who came to my house to give me an estimate for a tankless water heater. I was so very impressed. His customer service, extensive knowledge, and professionalism certainly earn the grade of an A+. A true reflection on black hills Inc.'s hiring practice of hiring and retaining only the best employees. My estimate included not only the tankless water heater but the full installation. Diamond Harris is an asset to your company. Black hills inc was referred to me by my parents who had 3 major projects completed by black hills Inc., and loved working with them. With employees like Diamond, I now see why. Such a positive experience. Thank you. Please give my sincere thank-you to Diamond

Awesome Customer Service

- Lillian B.

We spoke to 3 different companies to get an estimate for a new system. Black Hills was the only company that did exactly what they said they would do from the start. I appreciate the text/photo letting me know who would be arriving and he came right on time. Travis was very polite and professional and answered all of our questions. The installation crew was also very quick and professional and cleaned up afterward. Follow-ups to make sure we were happy with service also appreciated. Awesome customer service

Great Service

- Jordon C.

Great service, No BS. Our AC was not keeping up, had a feeling it was because of a leaking coil on the inner unit. Was confirmed by Black Hills Inc. and was set-up with an appointment with a comfort specialist. After the survey with the specialist (Bento Yanez), we sat down and discussed options for replacement, turning out that full replacement with a heat pump/ac/new furnace would be the most efficient cost-effective option. Black Hills was able to access all the previous history on our unit since prior homeowners had used them, they could pull up everything that had previous work done. Looking forward to the replacement unit being installed in only 4 days, after the survey.
