Air Sealing in Olympia, Washington

If you’ve noticed uneven heating and cooling, an increase in your energy bill, or even unusual noises coming from your HVAC system, then there might be a leak in your air ducts. Leaks in your air ducts increase the chance of allowing outside air and moisture into your home and force your HVAC system to work twice as hard.

If you suspect a problem with your air ducts, reach out to the experts at Black Hills. We offer duct sealing services in Olympia, Thurston County, and the Western Washington area.

Signs You Need Duct Sealing

If you are experiencing any of these common ductwork problems, call a professional to inspect your air ducts. 

  • High Energy Bills: A sudden rise in your energy bill could be a sign that your HVAC system is working harder than necessary due to air leaks in the ductwork.
  • Uneven Heating or Cooling: If certain rooms in your home are consistently warmer or cooler than others, it could mean that conditioned air is escaping through leaks in the ducts.
  • Visible Damage: If there are holes, cracks, loose connections, or disconnected segments, air is leaking through. 
  • Drafts or Cold Spots: Feeling drafts or experiencing cold spots in certain areas of your home, especially near air vents or ductwork, could indicate air leaks that need sealing.

Benefits of Duct Sealing

There are many benefits that come with duct sealing:

  • Improved energy efficiency and lower utility bills
  • Consistent temperatures throughout the home
  • Enhanced indoor air quality and reduced allergens
  • Extended lifespan of HVAC equipment
  • Quieter operation of the HVAC system

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.
