“Joplin’s has always taken great care of us for over 20 years. Today was fantastic as our AC went out over Father’s Day weekend. They came to our rescue within two hours of our call.”

Jennifer S.Customer review, joplins.net

“Had an outage on Labor Day in 105 degree heat in North Texas. Michael from Joplin’s was there in 1 hour and got our unit working again.”

Common questions

Do you offer emergency service?

Yes. Emergency service is available 24/7. Call 469-846-8339.

How long will my AC unit last?

Most well-maintained AC units last between 10 and 12 years. Heavy use in a hot climate can shorten that, and regular maintenance helps extend it.

What thermostat setting is best?

Home experts recommend about 68 in the heating season and 78 in the cooling season. A programmable thermostat avoids wasting energy while you are away.

Someone told me I need a new system. Can you check?

Yes. Joplin's gives a free second opinion on replacement quotes from other companies, with no pressure and no upselling.
