One room never seems to catch up with the rest of the house? 🏠

Notice which room it is and when the difference is most obvious. Make sure furniture, curtains, or rugs aren't blocking any visible vents. If the room stays uncomfortable, a qualified HVAC professional can check what's going on.

Olsen Air provides residential and commercial HVAC service across all of North Texas. Veteran and family owned and operated.

🇺🇸 Proud to stand behind those who have stood for us.

Olsen Air was proud to be a Platinum Sponsor of Texas Valor Project’s Boots & Brains Gala, supporting veterans and first responders living with traumatic brain injuries.

Texas Valor Project helps these men and women access specialized brain injury care, along with the travel and lodging support needed to receive treatment. Behind every person they serve is a family and a future worth showing up for.

Representing Olsen Air were David and Erica Olsen, alongside Andrew Dean, our very first employee and David’s right-hand man. We’re proud to have people who care about this community at the heart of our company.

Thank you to Texas Valor Project, the volunteers and everyone who came together to support this mission. To our veterans and first responders: thank you for your service and sacrifice. We’re grateful for the opportunity to give back.

Is your sink taking the scenic route? 🚰

A drain that keeps slowing down deserves attention. Notice whether it is one fixture or several, and whether you hear gurgling or see water backing up. If water is backing up, stop using the affected fixture and have a qualified plumbing professional take a look. Skip opening pipes or pouring in chemicals to guess at the cause.

Olsen Air LLC provides residential and commercial plumbing service across all of North Texas. Veteran and family owned and operated.

Things that go bump in the night belong in October movies—not your HVAC. 👀

A new, persistent rattle, bang, or grinding sound is worth paying attention to. Note when it happens and whether your heating or cooling has changed, then let a qualified professional check the system. Keep equipment panels closed.

Your thermostat isn’t a turbo button. 😅

If your home feels too warm or too cool, pushing the thermostat far past the temperature you actually want generally won’t make a typical system get there faster. Set it for comfort and give the system time to respond.

If it keeps falling short of the setting, or one room feels noticeably different from the rest, note what you’re seeing and when. That’s useful information to share with a qualified HVAC professional.

Olsen Air LLC is veteran and family owned and operated, Master Certified, and serves all of North Texas from Rockwall. For residential or commercial HVAC, mechanical, or plumbing service, call (469) 554-9748 or message us here on Facebook.
