David Guyer

Very prompt, efficient, and the repaired device is working perfectly.

Steve D

Joshua came out for a electrical inspection on our initial contract. He was all business and knocked it out in around 30 minutes. Nice guy…very professional

Mark Dunkum

Haller diagnosed the issue with my whole-house water filtration system quickly. It was repaired quickly as well. Friendly service person who explained the issues and solution to me. I already had their service plan for one hvac system, so I converted to a whole home plan to cover the water and upstairs hvac as well.

Nancy Chapman

Systems check up – did a great job very efficiently once arrived. Was a little Kate due to heat wave related emergencies!

Steve Lazun

Jesse is extremely knowledgeable. He diagnosed the problem with my AC that others had missed.

Tom C Reed

We purchased our HVAC system from Haller and also established a service contract. Today, Haller sent Christian to service our unit. He was right on time and quickly performed the checkup. These guys do a good job!

Katherine Eberly

Jesse was personable and professional! More than willing to answer questions and informative during the entire visit!

Mark Schettler

The Haller representative arrived punctually, and completed the inspection of our air conditioning system in a timely fashion. He also took the time to describe what he did, and the functionality of said system. He completed all of this in a very friendly and professional manor.

Ed Stone

Phil was very friendly and even enjoyed our two dogs and gave them a lot of love. Work was done effectively both inside and outside.

Larrimore Anderson

Gabe from Haller Enterprises arrived promptly when scheduled. He listened carefully to my questions/concerns and then made an honest effort to find answers/solutions. Although no immediate resolution to the main issue was found, Gabe promised to continue his search on his own and contact me promptly when he had success.

Domenic Martelli

In an out very professional

Jeannie D'Amico

Don Humenik was our technician. He came with another technician, I think his name was Larry though did not get a last name. I could not ask for a more professional, helpful and friendly experience. We just moved into our house which had one prepaid maintenance visit left from the previous owners. They honored that last maintenance check and so there was no fee to us. That says a lot about how they do business. Because of that, and reinforced by Don and Larry, I signed onto their yearly maintenance agreement. I feel like I finally have a trustworthy, competent, and fairly priced company to work with. Other companies I’ve dealt with in the past have hit one or two of those, maybe good to work with but really expensive. I feel like Haller hits all the marks.

Gale Zorian

Gabe is the best plumber❣️

Lois Walker

Jared Simington is an excellent technician representing Haller Enterprises, we will be asking for him in the event that we have HVAC issues. There was no charge because our AC was installed last year.

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.

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