So… how'd that AC test drive go? 👀

If everything ran cool, quiet, and smelled normal — congrats, you're set for summer. ☀️

If something felt off (warm air, weird sounds, weak airflow, a funky smell), don't wait to reach out.

Heil services Howard County, Montgomery County, Baltimore County, and beyond, and we’d be glad to take a look.

Quick PSA from your friendly neighborhood HVAC team: don't wait for the first 90° day to find out if your AC works. 🥵

Take it for a test drive on a warm spring afternoon — 15 minutes is all it takes. A small issue caught in May is almost always cheaper and easier to fix than a bigger issue in the middle of a heat wave.

Heil Plumbing & HVAC has been a family business since 1977, and the mothers in our family have been at the heart of it every step of the way.

From Miriam, who helped Joseph build this company from the ground up, to Laurie, who kept everything running behind the scenes, to Mengning, who helped carry us into a new generation — this business wouldn't be what it is without them.

Today, we celebrate them and every mom who pours herself into the people she loves. Happy Mother's Day from our family to yours. 💙

If you’ve ever had your HVAC system fail, you know it never comes at a convenient time.

It’s never planned. And it’s never cheap.

That’s why our HVAC Membership exists. For $95 per year, you get:

☑ AC tune-up
☑ Heating tune-up
☑ 15% off repairs
☑ Extended part warranties
☑ $500 Credit toward a new system

That’s less than the price of 2 tune-ups!

Less stress. Fewer surprises. More control. Learn more at https://heilplumbing.com/hvac-membership-plan/

We love Howard County and the incredible local businesses that make it special. 🙌

Today, we're highlighting UMI Sushi - Ellicott City. Featuring fresh Japanese cuisine and a beautiful outdoor patio overlooking the Tiber River, it’s a go-to spot for a relaxing lunch or dinner.

If you haven't been, you're missing out. And if you have — you already know. 🍣

Nobody thinks about their AC... until it stops working on the hottest day of the year. 😅

Don't be that person this summer. It only takes 15 minutes of DIY to:

→ Swap out the air filter
→ Peek at the indoor unit for any signs of moisture
→ Flip the thermostat to cool and make sure it kicks on
→ Clear any leaves or debris around your outdoor unit

That's it. You're ahead of half the neighborhood. Learn more here: https://heilplumbing.com/blog/hvac-tips/spring-hvac-maintenance-checklist/
