Now this is a satisfying transformation! 😲
In the before photo, you can see the evaporator coil buried beneath a thick layer of dust, debris, and buildup. That grime was restricting airflow and making it harder for the system to do its job.

After a professional cleaning, the difference is night and day! 🙌 The individual coil fins are visible again, clean and shiny, allowing air to move freely across the coil as designed.

Keeping your coils clean helps your HVAC system run more efficiently, keeps your home more comfortable, and can even extend the life of your equipment.

This is just one of the many reasons routine maintenance is so important. A little cleaning today can help prevent big problems tomorrow! 🦅

🤔 Should you repair your HVAC system or replace it?

The answer isn't always as simple as people think.

Before making a decision, Gilbert explains a few important things that should be considered:

✅ How old is the system?
✅ Is it still under warranty?
✅ Was it installed correctly in the first place?
✅ Why did the failure occur?
✅ Could the issue have been prevented?

Sometimes a simple repair can keep a system running reliably for years. Other times, investing in new equipment may provide better value, improved efficiency, and greater peace of mind.

Our goal isn't to push you toward a repair or a replacement. Our goal is to give you the information you need to make the best decision for your home, your budget, and your family's comfort.

At Allegiance Heating & Air, we believe informed homeowners make the best decisions—and we'll be right there with you every step of the way. 🦅

This weekend was a special one for the Allegiance team as we celebrated the marriage of one of our own, Lucas, and his beautiful bride, Kendall.💍🦅

The ceremony was absolutely beautiful, and while this selfie was unfortunately the only photo we managed to take, trust us when we say the bride looked stunning!

We couldn't be happier to see these two begin their forever together. Please join us in congratulating Lucas and Kendall and wishing them a lifetime filled with love, laughter, happiness, and countless blessings.

Congratulations, Mr. & Mrs. Schneider! 🥂❤️

Field Day fun with Greenville Elementary! 🏫

We had such a great time volunteering at Greenville Elementary School’s Field Day! Our team handed out popsicles while Ace joined in on the fun by playing games, taking photos, and making lots of new friends along the way.🦅

We’re so thankful Greenville Elementary allowed us to be a small part of such a special day. Seeing the kids’ excitement when they met Ace and got to spend time with him is one of the many reasons we love giving back to our community.❤️

Ed and Chyrell are the second local family we’ve had the privilege of blessing through Project Ace with a free HVAC installation. 🦅🇺🇸
From the moment we met them, we knew they were incredibly special people with hearts dedicated to serving others.

Ed proudly served our country in the United States Air Force, and his service is something we are deeply grateful for. But his impact didn’t stop there. Together, Ed and Chyrell have continued serving their community by refurbishing and opening a church where they help bring hope, faith, and support to those around them. Their passion for helping others and living out their faith was inspiring to witness firsthand. 🙌

When we learned more about their story and saw a couple who give so much to their community in need of a new HVAC system, we knew exactly what we wanted to do. Project Ace was created to give back to veterans in our local community, and being able to help people like Ed and Chyrell reminds us why this program means so much to all of us at Allegiance Heating & Air.

We would like to personally thank Ed and Chyrell for opening up their home to our team and trusting us to complete this work for you.😊 It was truly an honor getting to know you both throughout this process. Your kindness, hospitality, and servant hearts left a lasting impact on everyone involved in this project.

Giving back to our community is always a privilege, but Project Ace holds a very special place in our employees’ hearts. It’s more than just installing equipment — it’s about showing appreciation, building relationships, and giving back to the people who have sacrificed so much for others.

We’re incredibly thankful to work for a company that gives us the opportunity to serve local veterans and make a difference in the lives of families right here in our community.

Thank you again, Ed, for your service to our country. And thank you, Ed and Chyrell, for continuing to serve your community with such compassion, faith, and generosity. We are grateful to have crossed paths with you both. ❤️

🚩 3 red flags to watch for when an HVAC technician comes to your home this summer:

1️⃣ No gauges?
Without gauges, there’s no way to properly monitor your system’s refrigeration cycle or check if refrigerant levels are correct.

2️⃣ No electrical meter?
An electrical meter is a crucial part of the diagnostic process. It helps tell us important information about high voltage, low voltage, open safeties, and compressor health — all things that help a technician properly diagnose what’s going on with your system.

3️⃣ Trying to sell you a new system before explaining why your current one failed?
You deserve to understand what happened to your system before anyone talks replacement options.

If you’ve experienced any of these red flags, it may be time for a second opinion. 👀

Luckily, Allegiance Heating & Air offers FREE second opinion visits to help homeowners feel confident in their decisions. 🦅
