What Our Customers Are Saying

"Excellent service. Tech arrived quickly the day of system failure. Conversation with Karl discussed options & helped decide what to do. Replacement done quickly after weekend. All techs very pleasant & polite young men, very helpful. Entirely good experience under stressful circumstances.."

- Eleanor S.

"Keath HVAC was outstanding from start to finish. We shopped several of the top companies in the area, and Keath clearly stood out—not only for their quality and professionalism, but also for offering the best price. Ryan and Carter were knowledgeable, efficient, and extremely conscientious. They worked neatly, respected our home, and made sure everything was done right."

- Stephanie H.

"Keath HVAC replaced our Trane heat pump last summer. I will say the customer service is amazing. Did a great job on the install. Had them back today to refine our settings and again, great service. Ryan, Carter, Noah and Charlie are a great team to do business with. They stay on task but have fun as well. Nice to share some great conversation with them. The office staff is also very nice and are extremely attentive when we call. I give this company a 20 on a scale of 1-10. I wish we would have used them sooner."

- John L.

We Find the Problem. We Fix It Right. The First Time.

We service all major brands and models.

A lot of AC problems look the same on the surface (warm air, weak airflow, a unit that won’t shut off), but the causes can be completely different. Replacing parts that don’t need replacing is expensive and doesn’t solve anything. That’s why Keath technicians take the time to properly diagnose your system before recommending a repair. We service all major brands and models, whether we originally installed your equipment or not, and we’ll give you a clear explanation of what’s wrong and what it will cost before we start.

We service:

Central air conditioners
Heat pumps
Ductless mini-splits
Thermostats & zoning systems
Ductwork & ventilation

Catch Small AC Problems Before They Become Big Repairs

The most common AC repairs we see (low refrigerant, failing capacitors, dirty coils) are things a trained technician can spot during a routine tune-up before they cause a full breakdown. Our Comfort Care Club is built around that idea: regular attention now means fewer surprises later.

Members enjoy:

Two comprehensive seasonal tune-ups per year
Priority scheduling for service calls
Exclusive discounts on repairs and parts
Improved energy efficiency and lower utility bills

Nearly 30 Years of Getting It Right

Since 1996, Keath HVAC has built its reputation in Berks, Montgomery, and Lebanon Counties on one simple idea: do the job right and be straight with people about what it costs. No unnecessary repairs, no parts swapped on a guess, no invoice surprises.

Our technicians are certified and experienced — and they know that a callback for the same problem is a failure, not an opportunity. When they leave your home, the issue is fixed.
