Shawn arrived in the window the app provided. He was polite, friendly, and professional. I had scheduled just semi yearly check on the heating system before winter. Unfortunately, Shawn discovered my outdoor unit fan was leaking oil and my refrigerant pressure was lower than in the spring, indicating that may be a leak. He discussed all my options with me including ball park figures on a new unit. My wife and I decided to be proactive and replace the unit. He took all types of measurements for the sales office so they could give me as many options as possible. Within an hour after Shawn left, due to his thoroughness, we had a new unit ordered, financing, and install scheduled. Although that was not on my Bingo card for the day, the process was smooth and Shawn helped to make it so. Thank you!

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.

Common Air Conditioning Repairs Our Team Handles

During hot Pennsylvania summers, air conditioning systems can run into a variety of issues.

Haller’s experienced technicians are equipped to diagnose and repair a wide range of AC problems quickly and effectively.

Low refrigerant levels can prevent your system from cooling properly and may indicate a leak. We locate the source, repair the leak, and recharge your system to restore performance.

If your AC is blowing warm air or not working at all, frozen coils could be the cause. We identify the underlying issue — such as airflow restrictions or refrigerant problems — and get your system back to normal.

A malfunctioning thermostat can lead to inconsistent temperatures or a system that won’t turn on. We repair or replace faulty thermostats to ensure accurate control and reliable operation.

Worn or damaged electrical components can cause your system to short cycle or fail completely. Our team safely repairs or replaces parts like capacitors, relays, and wiring to keep your AC running smoothly.

Blocked drain lines can lead to water leaks and potential damage to your home. We clear clogs and ensure proper drainage to prevent future issues.

If airflow from your vents is weak or nonexistent, the blower motor may be the problem. We inspect, repair, or replace the motor to restore proper air circulation throughout your home.

Should You Repair or Replace Your Air Conditioner?

Deciding whether to repair or replace your air conditioning system can be a tough choice.

At Haller, we help you make confident, informed decisions by evaluating your system and recommending the most cost-effective solution for your comfort and budget.

If your air conditioner is more than 10 to 15 years old, it may be nearing the end of its lifespan. Older systems are less efficient and more prone to breakdowns, making replacement a smarter long-term investment.

Occasional repairs are normal, but frequent breakdowns can quickly add up. If you’re calling for service multiple times a season, it may be more cost-effective to replace your system.

Rising energy bills can be a sign that your AC is no longer operating efficiently. Newer systems offer improved energy efficiency, which can lower your monthly cooling costs.

A good rule of thumb is to compare the cost of the repair to the value of your system. If a repair is expensive and your unit is older, investing in a new system may provide better value and reliability.


Prevent Future Air Conditioning Problems with Regular Maintenance

Regular air conditioner maintenance is one of the best ways to prevent unexpected breakdowns and costly repairs.

With Haller’s Home Comfort Club, staying on top of maintenance is easy. Members receive scheduled tune-ups, priority service, and exclusive savings, making it simple to protect your AC system and enjoy reliable comfort all season long.
