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.

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.

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.
