🧹 A dirty filter is your AC’s worst enemy. It blocks airflow and makes your whole system work overtime — especially during a heat wave. Check your filter monthly and swap it out when it’s dirty. Simple fix, big impact.

If you need one more to-do list off your plate, our Preventative Maintenance Agreement can help. As a PMA customer, we call YOU twice a year to schedule your maintenance, clean your equipment, fully inspect it, and change your filter for you.

One less thing for you to remember and a wise investment to keep your equipment running efficiently for as long is possible.

A dirty outdoor A/C unit can make your system work harder than it has to.

One of the easiest homeowner maintenance tips is gently rinsing the outdoor condenser with a garden hose to remove dirt and debris.

🚫 Skip the pressure washer! Those aluminum fins bend easily, reducing airflow and efficiency.

Not sure if your system needs more than a quick cleaning? We’re happy to help.

☀️ 5 Ways to Help Your A/C Keep Up During Extreme Heat

When the heat index climbs into the triple digits, your air conditioner is working overtime. Here are a few simple things you can do to help it perform its best:

1. ✅ Change your air filter.
A dirty filter restricts airflow, making your system work harder than it needs to.

2. 🌡️ Don’t keep adjusting the thermostat.
Setting it lower won’t cool your home faster. Pick a comfortable temperature (a little closer #) and let your system do its job.

3. 🪟 Keep blinds and curtains closed.
Blocking direct sunlight can significantly reduce the amount of heat entering your home.

4. 🚪 Keep doors and windows closed.
Every time cool air escapes and hot air gets in, your A/C has to work even harder.

5. 🌿 Keep the outdoor unit clear.
Trim back weeds, grass, and shrubs, and remove any debris so your condenser can breathe.

💛 Remember: On days like these, it’s normal for your air conditioner to run for long periods or even continuously during the hottest part of the day. If it’s maintaining a temperature that’s within a few degrees of your thermostat setting, it’s often doing exactly what it should.

📞 If your system isn’t keeping up or you have concerns, give us a call. We’re always happy to help.

We asked three of our experienced installers and service technicians one simple question:

“What’s the #1 thing every homeowner should do to take better care of their HVAC system?”

We didn’t coach them. We didn’t compare answers.

All three immediately said the same thing…

👉 CHANGE. YOUR. FILTERS. 👏👏👏

A clean filter helps your system:
✔️ Breathe easier
✔️ Run more efficiently
✔️ Reduce unnecessary wear and tear
✔️ Improve your indoor air quality
✔️ Potentially help you avoid costly repairs

It’s one of the easiest (and least expensive) ways to protect one of the biggest investments in your home.

📅 If you can’t remember the last time you changed yours… this is your sign.

How long has it been since you checked your filter? 👇

Some things are bigger than softball. 💚🥎

Tonight our team plays its final tournament game of the season, and I can’t help but think about how special this league has been to our family.

Arnold Brothers has been sponsoring McDonough County Girls Softball League teams for as long as I can remember—nearly since the league began almost 40 years ago.

I grew up playing on Arnold Brothers teams, coached by my dad. My two younger sisters did too.

Now, years later, I’m standing on the same field coaching alongside my dad…this time with my own 10-year-old daughter wearing the jersey.

It’s pretty incredible to think about the thousands of girls, countless teams, and so many memories that Arnold Brothers has been blessed to be a small part of over the years.

We’re grateful for this community, for the volunteers who make this league possible, and for every player who’s ever put on an Arnold Brothers jersey.

Now let’s go finish this season the best way we know how. 💚🥎

Not every hero wears a cape.

Sometimes they drive a bright green van and show up with your house is 85 degrees in June or 60 degrees in January.

Thanks for choosing Arnold Brothers for your home comfort needs! 💚
