First time calling Haller for an electrical issue and ultimately a light replacement. Was given an appointment the next day, which I truly appreciated! The person that I spoke with to schedule the appointment was wonderful! And, Jason, the electrician was very knowledgeable about my situation and gave me two possible solutions. I picked one and he had the new light installed in no time! Will definitely call Haller again for future electrical needs. Thank you!

I've been using Haller Enterprises for a couple of years now, from purchasing a new heating and AC system from them and having them install it to doing maintenance through the current time. The system installation went without a hitch and was done to where the basement was left in pristine condition. They've always been great. More than great! Timely and tidy & super competent!

Annual preventative maintenance was easy to schedule when it fit best for me. The Haller rep arrived timely and was very professional. He reviewed his findings with me at the end and gave me plenty of time to ask any questions that I had. There were no hidden up charges or recommendations of expensive "added" services that weren't needed. I trust Haller for a quality job at a fair price and fully recommend them.

I called about the advertised $89 drain-cleaning special for a kitchen sink that was running slowly. After two technicians arrived in separate vans, they told me the special only covered main drains and quoted me $489 to $1,200. If kitchen sinks were excluded, that should have been explained when I scheduled the appointment, not after the technicians showed up. This felt like a bait and switch, and I wouldn’t recommend them. A waste of my time and theirs! UPDATE: Jason, the Senior Plumbing Team Leader, called me later that evening and apologized for the communication breakdown. He explained that the $89 ad had been worded too vaguely about what the special included. He offered to come back personally and clear my kitchen sink at no charge, which he did the next day. While inspecting the drain with a camera, he found significant buildup and two tight 90-degree PVC fittings that prevented the camera from going farther. He recommended replacing them with sweeping bends for a reasonable additional price. Even just running the camera improved the drain, and I appreciated Jason’s follow-up and willingness to honor my original request. I changed my rating from 1 star to 4 stars because of his follow-up and communication. He’s a good guy, and I wouldn’t hesitate to call Haller Enterprise again for service. Any company can make a mistake; what matters is how they respond to it.

Benefits of a Furnace Replacement in Bethlehem

Replacing your furnace is an investment in comfort, efficiency, and long-term reliability.

If your current system is outdated or unreliable, furnace replacement in Bethlehem can dramatically improve your home’s performance and lower your stress during Pennsylvania’s cold winters. Discover the benefits Bethlehem homeowners notice with a new furnace:

New high-efficiency furnaces installed in Bethlehem use less fuel to produce the same or better level of warmth. Furnace replacement pays for itself through lower monthly bills. That means you can enjoy improved comfort while potentially reducing your monthly heating costs.

An older furnace in Bethlehem is more likely to break down during the coldest stretches of a Pennsylvania winter. A new system provides dependable heating and reduces the risk of unexpected mid-winter repairs.

Modern furnaces distribute heat more evenly throughout your Bethlehem home. You’ll experience fewer cold spots and more consistent temperatures from room to room.

Today’s furnaces installed in Bethlehem homes are built with advanced safety controls and monitoring systems. Replacing your aging unit helps minimize risks such as carbon monoxide leaks and system malfunctions.

Time to Replace Your Furnace? Look for These Signs

Knowing the warning signs of a failing furnace can help you avoid a complete breakdown. These are the situations where furnace replacement in Bethlehem is often the smartest move.

If you’re calling for furnace repairs in Bethlehem more often than usual, those costs can quickly add up. Furnace replacement in Bethlehem is often more cost-effective than continuing to fix an aging unit.

An unexplained increase in heating costs in your Bethlehem home often signals declining efficiency. Older furnaces work harder to produce heat, using more energy while delivering less consistent comfort.

Cold spots or rooms that never seem warm enough can point to a struggling system. As furnaces age, they often lose the ability to distribute heat evenly and effectively.

Most furnaces in Bethlehem have a lifespan of about 15 to 20 years with proper maintenance. If your system is nearing or beyond that range, replacing it can improve reliability, efficiency, and overall comfort in your Bethlehem home.
