Our Step-by-Step Process for Furnace Installation

Installing a new furnace is more than just swapping old equipment for new. It requires careful planning, safety considerations, and precision execution. At Haller Enterprises, we follow a detailed process to ensure every installation meets our high standards.

Our process begins with a thorough assessment of your home’s layout, insulation, and existing ductwork. This step allows us to identify the most effective furnace options for your space. Proper sizing and placement are critical to maintaining efficiency and comfort throughout the year.

After evaluating your home, we present personalized recommendations with clear pricing before any work begins.

Technicians install your furnace with attention to detail, following strict safety protocols. Every connection, vent, and control is double-checked to ensure safe and efficient operation. Before leaving, we perform comprehensive tests to confirm the system is performing as intended, then review your new system’s operation and provide tips for maintaining peak efficiency, including guidance on filters, controls, and seasonal checks.

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.
The service was extraordinary. My service person was polite, informative and customer centric. This person is the type of person you want engaging with people. I also learned some good ac and furnace tips. I give Shane 5 stars….out of 5.
Nate was very nice to work with and very professional.
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.

Common Signs You Need a New Furnace

Recognizing the warning signs early can prevent disruptions during the coldest months.

Our team helps homeowners identify problems before they become emergencies.

Banging, rattling, or whistling sounds often indicate worn components or airflow problems. Ignoring these noises can cause further damage or decrease efficiency. Early evaluation ensures your heating system maintains both performance and safety. By addressing these sounds promptly, you can prevent costly repairs and enjoy a quietly operating furnace all season long.

If some rooms feel warmer than others, your furnace may be struggling to distribute heat properly. This can result from duct leaks, aging parts, or an underpowered system. Addressing the issue restores consistent comfort and helps prevent energy waste. Fixing uneven heating ensures every room stays cozy and comfortable, no matter the temperature outside.

Furnaces that need repeated repairs often signal the system is reaching the end of its lifespan, and an unexpected spike in heating costs reflects declining efficiency. Both patterns mean the cost of continuing to service the existing unit is outpacing the value of keeping it. Taking action early helps avoid emergency situations and keeps your home warm when you need it most.

Furnaces that aren’t functioning properly may circulate dust, allergens, or moisture throughout your home, and most furnaces last 15 to 20 years before age makes them less efficient and more prone to unexpected failure. Upgrading or servicing your system can restore clean airflow and healthier conditions while ensuring consistent warmth for many winters to come.

Additional Types of Heating Systems Haller Enterprises Installs

Every home is different, and Central and Eastern Pennsylvania residents need options that fit their property and lifestyle.

Haller Enterprises installs a variety of systems to meet those needs. Whether you’re upgrading an old system or building new, we match solutions to your home’s unique heating requirements.

Heat pumps provide both heating and cooling in a single system. They extract warmth from outdoor air, even in cooler temperatures, and circulate it indoors efficiently. Many homeowners enjoy year-round comfort and lower energy costs with these versatile systems. Proper installation ensures your heat pump operates reliably through both winter chills and summer heat.

Geothermal systems rely on underground temperatures to heat and cool homes efficiently. Fluid circulates through buried loops, transferring heat between the earth and your home. While installation requires specialized expertise, the long-term energy savings and comfort are significant. Geothermal systems can dramatically reduce energy bills while providing steady, quiet heating and cooling year-round.

Boilers remain a trusted heating solution for homes that use radiant heat. Modern boilers are highly efficient and can be paired with water-based heating systems. Our technicians ensure proper sizing, installation, and testing for lasting warmth and reliability. A well-installed boiler delivers consistent, even heat throughout your home, keeping floors and living spaces comfortable during the coldest Pennsylvania winters.
