We had been having air conditioning issues for a couple years where we had to fix it multiple times a year. We discussed the issues with our current air conditioning repair company who said the problem was the ac was getting near end of life and was struggling to keep the house cool when it got hot out. We asked them to give us a quote to replace the system. The person who came out only wanted to sell us on heat pumps and a lower quality air conditioner than what we had. So we contacted Haller to come out to give us a second opinion. One of their sales people ( Alex Steffy) came out looked at our current system and provided us with a variety of options to address our issue. He was very professional knowledgeable and polite. He explained why we had issues and how we should possibly remedy them. He provided 3 separate quotes outlining exactly what what equipment we would be getting and the cost for each option. The installation was done quickly and professionally by two gentlemen. The even offered a 5 year warranty though Haller in addition to the 10 year warranty by carrier. They may be a bit more expensive but I believe the service and care your get from them is worth the extra money.

We had an issue with what looked like a tiny drip in the basement, but Nathan who was amazing (friendly, caring and very professional) spent the necessary time checking out all the area. He found a bird had built a nest in the dryer outside vent causing this crazy scenario. He found it and fixed it that same day. 100% satisfied from this service.

Scheduled an estimate for what we thought would be a complicated fix. Arrived on time, pleasant, thoroughly assessed the situation, made his professional recommendations, and didnโ€™t try to upsell me on any extra repairs that werenโ€™t urgent, and actually let us know that the wiring situation didnโ€™t require an expensive replacement or re-wiring, just someone comfortable with that specific wiring and hardware layout. Would call them again.

Jason from Haller-Electric did a great job troubleshooting an issue in our old home. Quickly diagnosing our issue and solving our problem, and he did so with a positive, conscientious and professional attitude. Well done and thanks!
Shawn was excellent as diagnosing a problem that was not previously identified by other technicians. He explained it very clearly and was doing so in our best interest. He was not pushy or come off as โ€œa salesmanโ€, just letting us know what the issue was. I will definitely be requesting him to do all future maintenance and repairs!

The technician, Eric , called in the morning of my ac and furnace installation to let me know he was on his way. Upon arrival he and Connor reviewed the process for the day and layed down plastic to prevent damage to my floors. Another gentleman joined them at some point to complete the job. overall very satisfied with courteousness and professionalism. Haller came recommended and would do the same for anyone looking for installation or yearly maintenance services.

Frequently Asked Questions

How do I know if my air conditioner needs professional repair in Lehigh?

Your AC likely needs professional attention if you notice warm air blowing from vents, reduced airflow, strange sounds, or the system turning on and off repeatedly. Rising energy bills without increased usage also signal potential problems. Pennsylvania’s humid summers put extra stress on cooling systems. Any decline in your home’s comfort levels warrants a professional diagnosis to prevent bigger issues down the road.

How quickly can Haller respond to an AC repair request in Lehigh?

We typically schedule regular AC repairs within 24-48 hours, but emergency calls get immediate attention any time of day or night. Pennsylvania’s hot, humid summers can turn a broken air conditioner into a real problem fast. We prioritize getting technicians out quickly when your cooling system fails. For urgent situations in Lehigh, our emergency service means you won’t be stuck sweating through the night waiting for help.

Do you repair all brands of air conditioners in Lehigh?

Our technicians work on all major air conditioning brands and models throughout Lehigh, PA. We maintain specialized training and factory authorization as a Carrier dealer, which gives us deeper expertise with those systems. Our team handles everything from Trane and Lennox to Goodman and Rheem with the same professional skill.

Is it better to repair or replace my air conditioner in Lehigh?

The repair versus replacement decision comes down to three main factors: your system’s age, repair costs, and breakdown frequency. Systems over 10-12 years old that need expensive repairs often make better candidates for replacement. This is especially true in Lehigh’s demanding summer climate where older units struggle to keep up efficiently. Our technicians will assess your situation and give you straight answers about whether fixing your current system makes financial sense or if replacement would serve you better long-term.

Will you provide an estimate before starting the repair in Lehigh?

Absolutely. Our technician will complete a full system diagnosis and walk you through the repair options with transparent pricing before starting any air conditioning repair in Lehigh, PA. You’ll understand exactly what’s wrong with your system and what it takes to fix it. No unexpected costs or surprises along the way.
