Our church in Downingtown recently constructed a memorial garden. This was a fairly diverse project that required masonry, landscaping, and electrical crafts. We selected Hallar for the electrical portion of the project which required them to work closely with the mason in order to ensure a coordinated installation. Things went very well and the end result was a very successful project. Hallar installed the lights and a timer system which make for a very subdued and quiet setting in the evenings. In addition, during excavation for the masonry walls, our water service pipe was damaged. Because Hallar’s is a multi-craft company they were able to make the necessary repairs to the water line without any disruption to the project schedule at a very reasonable price. We would recommend Hallar’s for any project which requires electrical, plumbing, or HVAC expertise. They are proven to be cooperative, timely and highly skilled.

Wesley arrived at the designated time frame the appointment was made. He answered all are questions and addressed the concerns we had. The HVAC inside system is located in the attic and is not easily accessible. Wesley brought a ladder and was able to get the job done. He was very polite and honest. He also made sure to wear foot coverings while inside the house. A job well done!

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.

I scheduled a full HVAC inspection and service going into this winter season. Haller tech Shawn arrived on schedule inspected the system and while delivering not the best of news gave me a number of very satisfactory solutions, that was on a Friday, Tuesday the following week the installers arrived. The HVAC installation team, Edwin and Conner were on time, exceptionally courteous, knowledgeable. The entire old system was dismantled, removed and the new system installed. The final price was exactly as quoted by Haller rep. Josh Rivera and the new HVAC system is 100% operational. If you need to work with a professional staff send for Haller.

Frequently Asked Questions

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

Your AC likely needs professional attention if you notice warm air blowing from vents, reduced airflow, strange sounds, or the system turning on and off repeatedly. Rising energy bills without increased usage also signal potential problems. Pennsylvania’s humid summers put extra stress on cooling systems. Any decline in your home’s comfort levels warrants a professional diagnosis to prevent bigger issues down the road.

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

We typically schedule regular AC repairs within 24-48 hours, but emergency calls get immediate attention any time of day or night. Pennsylvania’s hot, humid summers can turn a broken air conditioner into a real problem fast. We prioritize getting technicians out quickly when your cooling system fails. For urgent situations in Lehigh, our emergency service means you won’t be stuck sweating through the night waiting for help.

Do you repair all brands of air conditioners in Lehigh?

Our technicians work on all major air conditioning brands and models throughout Lehigh, PA. We maintain specialized training and factory authorization as a Carrier dealer, which gives us deeper expertise with those systems. Our team handles everything from Trane and Lennox to Goodman and Rheem with the same professional skill.

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

The repair versus replacement decision comes down to three main factors: your system’s age, repair costs, and breakdown frequency. Systems over 10-12 years old that need expensive repairs often make better candidates for replacement. This is especially true in Lehigh’s demanding summer climate where older units struggle to keep up efficiently. Our technicians will assess your situation and give you straight answers about whether fixing your current system makes financial sense or if replacement would serve you better long-term.

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

Absolutely. Our technician will complete a full system diagnosis and walk you through the repair options with transparent pricing before starting any air conditioning repair in Lehigh, PA. You’ll understand exactly what’s wrong with your system and what it takes to fix it. No unexpected costs or surprises along the way.
