Very prompt, efficient, and the repaired device is working perfectly.
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
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.
Systems check up – did a great job very efficiently once arrived. Was a little Kate due to heat wave related emergencies!
Jesse is extremely knowledgeable. He diagnosed the problem with my AC that others had missed.
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!
Jesse was personable and professional! More than willing to answer questions and informative during the entire visit!
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.
My experience today was great.my technician was prompt, courteous, thorough and extremely professional. I'd certainly recommend.
Ron was excellent
These guys came out same day and did an excellent job. Customer service and workmanship is great. I love how they have 24/7 service. Would recommend them to anyone.
Excellent service!
Micheal came put and was GREAT! They sent him in a timely manner
Colin did a good job. We as yet havenโ€™t solved the problem
Jared is very professional, great attitude and attention to detail. Stellar service is always greatly appreciated and highly recommend Haller Enterprises for heating and air conditioning. Thank you for speedy and efficient service!!!
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.
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.
In an out very professional
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 Iโ€™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.
Gabe is the best plumberโฃ๏ธ
Mark was great, had a new toilet and a hot water tank installed,guy know what he was doing Definitely he is a keeper Thanks Mark
Shane and Matt are two pros who are really good at their job!!! We are very happy with their work…. thank you
Jared was on time, repaired and replaced our pump on our air conditioning unit and was very professional. He also explained the problem and explained what the solution was and then did what was needed.
Dude was friendly and professionalโ€ฆ top notch!
Good service….quick response

Frequently Asked Questions

What HVAC services does Haller provide?

Haller provides complete heating and cooling services for Fountain Hill homes. This covers repair, installation, replacement, and regular maintenance on all types of equipment. We service furnaces, heat pumps, boilers, ductless mini-splits, and central air systems to handle Pennsylvania’s demanding seasonal temperature swings. Our technicians are trained on both traditional and modern HVAC equipment. Got an older boiler or a new high-efficiency heat pump? We can keep it running properly.

How often should I schedule HVAC maintenance?

Your heating system needs professional maintenance once yearly. Schedule it before cold weather hits. Your cooling equipment needs the same attention before summer arrives. Pennsylvania’s harsh winters and humid summers stress HVAC equipment hard. These tune-ups catch small problems before they become expensive repairs. Regular maintenance keeps your system running well. It helps you avoid those middle-of-the-night breakdowns when you need heat or AC most.

Do you offer 24/7 emergency HVAC services?

Yes, we provide 24/7 emergency HVAC services for urgent heating and cooling issues. If your system stops working during extreme Pennsylvania temperatures, we respond quickly to restore comfort and safety.

How do I know if I should repair or replace my HVAC system?

Age is usually the biggest factor. Your HVAC system hits 10 to 15 years old and starts needing repairs every season? Replacement often makes more financial sense than continuing to fix an aging unit. Systems that can’t keep up with Fountain Hill’s temperature swings tell you they’re worn out. Same goes for units that run constantly without reaching your set temperature. A good technician will look at your equipment’s condition, how well it’s running, and what those repair costs add up to over time.

Can a new HVAC system help lower my energy bills?

Modern HVAC systems can cut your energy bills big time compared to older equipment. This matters in Fountain Hill where Pennsylvania’s temperature extremes make your system work harder. Today’s high-efficiency units use advanced technology that wastes far less energy than systems from even 10 years ago. Getting the right size for your home helps. Pairing it with a programmable thermostat increases those savings, since the system won’t cycle on and off as much or run longer than needed.
