Keep Your HVAC Unit Clean Between Service Appointments 🌬️ Your HVAC system works hard for you year-round here in East Texas! In between your scheduled maintenance visits, a little upkeep goes a long way in keeping your system running efficiently and avoiding costly repairs.

Here are a few simple things you can do:

✅ Change your air filter regularly
A dirty filter restricts airflow and makes your unit work harder. Check it monthly and replace as needed.

✅ Keep the outdoor unit clear
Remove leaves, grass, and debris from around your condenser. Make sure there’s at least 2 feet of clear space around it.

✅ Rinse off the outdoor coils
Gently spray the unit with a water hose (power off first!) to remove dirt buildup.

✅ Check your vents inside
Make sure furniture or rugs aren’t blocking airflow.

Taking these small steps helps improve efficiency, lower energy bills, and extend the life of your system.

If it’s been a while since your last tune-up, let’s get you scheduled!

❤️ “Y’all better discuss AC temperature before getting married.”

No truer words have ever been spoken in Texas.

68° vs 74° isn’t just a preference… it’s a lifestyle decision.

Before you argue over the thermostat, make sure your system can actually keep up. If your unit is struggling, running constantly, or not cooling evenly — it might be time for a tune-up or repair.

At Keystone Heating and Air, we help couples stay comfortable AND married. 😎❄️🔥

Did you know dust and debris cause up to 40% of HVAC breakdowns? 🤯

Dirty filters, clogged coils, and debris buildup restrict airflow, overwork your system, and can lead to expensive repairs—sometimes even compressor failure.

Regular maintenance helps:
✔ Prevent breakdowns
✔ Improve indoor air quality
✔ Lower energy bills
✔ Extend equipment life

Most of these failures are 100% preventable with routine service.

Did your heater not run as you thought it should during this past ice storm?

After 25 years in the HVAC industry, we’ve seen firsthand how extreme cold exposes hidden issues in heating systems—especially here in Texas, where ice storms push equipment beyond what it normally sees.

If your home struggled to stay warm, ran constantly, tripped breakers, or relied heavily on emergency heat, it may be a sign of:
• Worn or failing heat strips
• Weak contactors or electrical components
• Heat pump performance issues in freezing temperatures
• Poor airflow or ductwork restrictions

The good news? Many of these problems can be repaired or corrected without a full system replacement. A professional inspection now can help prevent higher energy bills, unexpected breakdowns, and uncomfortable cold snaps down the road.

We always recommend getting your system checked before the next freeze hits. Experience matters—proper diagnostics can save you thousands and give you peace of mind when the weather turns harsh again.

❄️ Stay warm. Stay prepared. ❄️

Freeze temps are hitting Texas ❄️ Longer heat pump run times are normal — no heat or heavy ice is not. If something feels off, don’t wait. Stay warm and protected.

We received a second opinion call this afternoon. Inspected the system and found the contactors with burned switching coils and not activating their electric heat. Previous company’s diagnosis was that they needed a circuit board and a whole new set of heat strips. We always recommend getting a second opinion especially with the high cost of repairs that can happen. We saved this customer over $1,500.00 today and earned a customer for life.
