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.

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.
