⭐⭐⭐⭐⭐ CUSTOMER REVIEW

There’s nothing better than hearing from a customer a year and a half after installation and knowing their system is still keeping them comfortable through it all—from snow and ice to 95°+ Georgia heat! 🙌

We take pride in quality work, dependable service, and making sure our customers are taken care of from start to finish. Reviews like this mean more to our small business than you know. ❤️

Thank you, Trent, for trusting Deerman HVAC and for taking the time to share your experience!

🔊 Tip Tuesday: Strange HVAC Noises

Your HVAC system should be relatively quiet. If you suddenly start hearing unusual noises, don’t ignore them—they’re often your system’s way of telling you something isn’t right.

Here are a few sounds to watch for and what it could possibly mean:
• Banging – Loose or broken internal parts
• Squealing – Worn belt or motor bearing
• Grinding – Motor or blower problems
• Hissing – Possible refrigerant leak or air leak
• Rattling – Loose panels, screws, or debris

The sooner you have a strange noise checked, the better your chances of preventing a much larger (and more expensive) repair.

If your system starts making a sound that doesn’t seem normal, give us a call. We’d rather help you catch a small problem before it becomes a big one.

💡 Tip Tuesday

One of the most common questions we get is:

“If I turn my thermostat way down, will my house cool faster?” 🤔

The short answer is no.

➡️ As a general rule of thumb, most air conditioning systems are designed to maintain about a 20° difference between the outdoor temperature and your indoor temperature under normal conditions.

For example:
☀️ If it’s 90° outside, most systems can comfortably maintain around 70° inside.

Trying to cool your home to 65° on a 90° day usually won’t make it cool any faster. It simply means your system may run much longer trying to reach a temperature it wasn’t designed to maintain under those conditions.

Every home and every system is a little different, but keeping realistic expectations during the hottest part of the summer can help your system perform its best while keeping you comfortable.

If you ever have questions about how your system is performing, we’re always happy to help.

Another family is staying cool thanks to a brand-new system! ❄️☀️

There’s nothing better than leaving a customer with dependable comfort and knowing the job was done right.

This week we completed a 4-ton Rheem heat pump and air handler installation, taking the time to make sure everything was installed cleanly, professionally, and with attention to detail.

Whether it’s a repair or a complete system replacement, our goal is always the same—provide honest service, quality workmanship, and treat every home like it’s our own.

Thank you to another customer for trusting Deerman HVAC. We truly appreciate every opportunity to earn your business.

💨 If your HVAC system can’t breathe, it can’t cool.

Your air filter is your system’s first line of defense.

When it gets clogged with dust and dirt, airflow drops—and that’s when problems start.

Don’t wait until your house isn’t cooling.

Take one minute today to check your filter.

Your HVAC system will thank you!
