Had our power lines to the house taken down during a big storm, the folks at Haller were great at getting out quickly to check out the damage and give us an estimate to repair. We put a down-payment down to reserve service, ended up not needing them, and they promptly refunded our payment with zero fuss. Good experience, I recommend them

From Haller doing a routine check on my HVAC and noticing the the water heater leaking to the estimate to scheduling the replacementโ€ฆ then having to change the appointment because of leaving for a vacationโ€ฆ. Courtesy, professional, and the Plummer that did the job Shane was seriously great. Iโ€™m thankful.

Garage toilet replacement.
Opted to provide own fixture and Haller requested for install. Mark Habbershon did a great job in removal, prep work, install, test & cleanup. . Confirmed improved trap dimensions for the new unit and much less likely to clog like old toilet with narrower trap. Very friendly and eager to do a quality job! Bravo Mark!!
Repair man was amazing nice and kind , unfortunately it was on the 4th of July and the rates were a lot higher ! But the repair man was great would highly recommend
Excellent experience with Shane Keifer on water heater installation. In addition a shout out to Amanda for helping get us booked in a very timely and friendly manner.
Christopher is wonderful and came out quickly . He is very professional and friendly. He took care of my central air and resealed the unit in the house. Closed the vents that are not being used to keep the cold air where I needed it. I would ask for Christoper the next time I had an issue.
Haller is best.
The technician, Adam, was excellent. He explained what the problems were, and showed me the problems on my outdoor fan. He was very patient and polite. I am hard of hearing, so he spoke louder. He fixed everything, and thought of solutions that had not been mentioned to me before – like using a 2" filter instead of a 1" filter to possibly cut down on filter changes (since I cannot change them myself). He also explained how the $24/month plan worked, and set me up for that when I decided to go with it. He answered all my questions. Adam is an excellent Haller employee.
Prompt competent, courteous service
Tech Nevin top notch w/ customer service. Extremely thorough.
Adam B was really amazing to have service my AC unit. He explained things thoroughly and completed everything in a timely fashion. Future services will request him.
Excellent service
Service tech, Phil R. arrived as scheduled, diagnosed the problem quickly and replaced the part on the spot. Thank you Phil for your professionalism and your kind, personable service.
He did an excellent job. ๐Ÿ‘ He is very friendly and kind.
My air conditioner was repaired by Neffsville, but it failed again in just over a month. When it stopped working, I was told it would be four days before they could come back out (itโ€™s 101 degree outside!).

I called Haller Enterprises instead, and they had a technician at my home within 24 hours. Jesse B. was knowledgeable, professional, and took the time to explain the issue and the repair. He diagnosed the problem quickly and completed the repair efficiently.

The difference in responsiveness and overall service was night and day. Based on my experience, I highly recommend Haller Enterprises for your HVAC needs. Thank you, Jesse, and the Haller team, for taking great care of us!
Adam B. came out on an extremely hot day and got the air fixed up and running well as soon as they got my call. He was very polite and friendly and explained everything he needed to do. I would highly recommend the company.
Very professional and tells you exactly what is going on. Highly recommend.

How to Know If It’s Time for a New Air Conditioner

Your air conditioner may need replacement if it’s struggling to keep up with Lehigh’s summer heat demands.

Higher energy bills, uneven cooling, and frequent breakdowns often signal that your aging or inefficient AC system in Lehigh needs replacement. Air conditioning installation in Lehigh becomes the smart choice in these situations. Recognizing these warning signs early helps you avoid sudden system failures and allows time to plan for a more reliable, energy-efficient upgrade.

Constant summer repair calls mean costs pile up fast. An older unit approaching the end of its lifespan may cost more to maintain than replacing it with a new system would.

Cooling costs in your Lehigh home climb suddenly or gradually increase over time. This typically indicates your system’s efficiency is declining. Modern air conditioning systems deliver more consistent comfort while using significantly less energy.

Temperature variations from room to room in your Lehigh home often signal that your current system struggles with proper air distribution. Professional replacement with correctly sized equipment can bring back the balanced, even cooling your family needs.

Air conditioners in Lehigh typically provide 10 to 15 years of reliable service with proper maintenance. Units reaching this age range that show wear patterns benefit from replacement, as upgrading delivers improved reliability and peace of mind for Lehigh homeowners.

Types of Air Conditioning Systems We Install

From central air systems to ductless mini-splits, Haller installs high-performance air conditioning solutions designed for Lehigh homes’ specific cooling requirements.

Based on your home’s layout, energy goals, and budget, our team will guide you to the right solution that delivers long-lasting comfort and efficiency for your Lehigh property.

For Lehigh homes with existing ductwork, central air conditioning systems deliver ideal whole-home cooling with consistent temperatures throughout. High-efficiency models available today provide reliable performance during peak summer heat while offering improved energy savings and quieter operation.

For Lehigh homes lacking existing ductwork or needing targeted room cooling, ductless mini-split systems offer a flexible air conditioning installation solution. These systems provide zoned comfort control and improved efficiency while allowing for easy installation with minimal disruption to your home.

Heat pumps deliver both cooling and heating capabilities, which makes them an excellent air conditioning installation option for Lehigh homeowners focused on energy efficiency. Rather than generating heat, these systems transfer it from one location to another, allowing Lehigh residents to cut energy consumption while enjoying consistent comfort throughout the year.

Air Conditioning Installation FAQs

How do I know what size air conditioner my home needs in Lehigh?

Your home’s square footage, insulation quality, existing ductwork, and room layout all help determine the right AC size for your Lehigh property. An undersized unit will struggle during Pennsylvania’s humid summers. An oversized system cycles on and off too frequently, wasting energy and creating uneven temperatures. Our technicians conduct a thorough assessment of these variables during your consultation to match the equipment capacity to your home’s specific cooling needs.

How long does air conditioning installation take in Lehigh?

A typical air conditioning installation in Lehigh takes one full day from start to finish. Jobs requiring ductwork changes or electrical upgrades can extend to two days, depending on your home’s specific needs. Our technicians assess the scope during your consultation and give you an exact timeframe so you know what to expect.

Do you offer financing for AC installation in Lehigh?

Yes, we provide financing options that make air conditioning installation in Lehigh, PA, more affordable for homeowners. We also serve nearby Walnutport and surrounding areas. Our specialists explain the different payment plans available so you can find one that works with your financial situation.

What’s the average lifespan of a new air conditioner in Lehigh?

A properly installed air conditioning system typically provides 10 to 15 years of reliable service in Lehigh, PA. Regular maintenance plays a crucial role in reaching that full lifespan. Neglected systems often fail earlier due to dirty coils, clogged filters, and worn components. Our Home Comfort Club maintenance program helps protect your investment by keeping your AC running at peak performance throughout its expected life.

Is professional installation really that important in Lehigh?

Professional installation makes a significant difference in how well your air conditioning system performs and how long it lasts. Incorrect installation can void manufacturer warranties, reduce efficiency by 20-30%, and lead to premature breakdowns that cost far more than the initial installation savings. In Lehigh’s humid summers, an improperly installed system struggles to maintain consistent temperatures. It often develops refrigerant leaks or electrical issues. Our certified technicians follow manufacturer specifications and local codes during air conditioning installation in Lehigh, which protects your investment and keeps your system running reliably for its full expected lifespan.
