First time calling Haller for an electrical issue and ultimately a light replacement. Was given an appointment the next day, which I truly appreciated! The person that I spoke with to schedule the appointment was wonderful! And, Jason, the electrician was very knowledgeable about my situation and gave me two possible solutions. I picked one and he had the new light installed in no time! Will definitely call Haller again for future electrical needs. Thank you!

I've been using Haller Enterprises for a couple of years now, from purchasing a new heating and AC system from them and having them install it to doing maintenance through the current time. The system installation went without a hitch and was done to where the basement was left in pristine condition. They've always been great. More than great! Timely and tidy & super competent!

Annual preventative maintenance was easy to schedule when it fit best for me. The Haller rep arrived timely and was very professional. He reviewed his findings with me at the end and gave me plenty of time to ask any questions that I had. There were no hidden up charges or recommendations of expensive "added" services that weren't needed. I trust Haller for a quality job at a fair price and fully recommend them.

I called about the advertised $89 drain-cleaning special for a kitchen sink that was running slowly. After two technicians arrived in separate vans, they told me the special only covered main drains and quoted me $489 to $1,200. If kitchen sinks were excluded, that should have been explained when I scheduled the appointment, not after the technicians showed up. This felt like a bait and switch, and I wouldn’t recommend them. A waste of my time and theirs! UPDATE: Jason, the Senior Plumbing Team Leader, called me later that evening and apologized for the communication breakdown. He explained that the $89 ad had been worded too vaguely about what the special included. He offered to come back personally and clear my kitchen sink at no charge, which he did the next day. While inspecting the drain with a camera, he found significant buildup and two tight 90-degree PVC fittings that prevented the camera from going farther. He recommended replacing them with sweeping bends for a reasonable additional price. Even just running the camera improved the drain, and I appreciated Jason’s follow-up and willingness to honor my original request. I changed my rating from 1 star to 4 stars because of his follow-up and communication. He’s a good guy, and I wouldn’t hesitate to call Haller Enterprise again for service. Any company can make a mistake; what matters is how they respond to it.

Frequently Asked Questions

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

Your AC likely needs professional attention if it’s blowing warm air, producing weak airflow, making strange sounds, turning on and off repeatedly, or driving up your energy costs. These problems often start small but worsen quickly during Pennsylvania’s hot summers. This is especially true in areas like Cedar Crest Boulevard where older homes may have aging ductwork. Professional diagnosis will identify the root cause and prevent more expensive repairs down the road.

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

We typically schedule non-emergency AC repairs within 24 hours. Our 24/7 emergency service responds immediately to urgent cooling failures in Emmaus. Response times for emergency calls are usually within a few hours, depending on your location and current service demand. During peak summer months in Pennsylvania, multiple systems fail simultaneously. We prioritize calls based on severity but still maintain fast response times throughout Lehigh County.

Do you repair all brands of air conditioners in Emmaus?

Our technicians work on all major air conditioning brands and models throughout Emmaus. This includes older units common in homes near South Mountain to newer high-efficiency systems. Being a Carrier Factory Authorized Dealer gives us additional training and access to genuine parts for Carrier equipment. We handle everything from Trane and Lennox to Rheem and Goodman with the same level of expertise.

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

The decision comes down to three main factors: your system’s age, repair costs, and breakdown frequency. If your AC is over 12-15 years old and needs expensive repairs, replacement often makes more financial sense. This is especially true given Pennsylvania’s demanding summers that stress aging equipment. Systems requiring multiple repairs each season typically cost more to maintain than replacing. Newer units with isolated problems are usually worth fixing.

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

Absolutely. We provide a complete estimate after diagnosing your cooling system but before starting any air conditioning repair in Emmaus. Our technician will walk you through exactly what’s wrong, what needs to be fixed, and what it will cost. You’ll have all the information you need to make the right decision for your home and budget. No hidden fees or unexpected charges.
