DeLong & Sons HVAC is a family-owned company that installs and services heat pumps, furnaces, boilers, central air, tankless water heaters, and standby generators for homes throughout Emmaus, PA and the Emmaus-Wescosville-Macungie corner of Lehigh County. We are based in Shoemakersville, and while that is a short drive from the borough, Emmaus homeowners keep our number because we size systems correctly, quote the work up front, and stand behind what we install.
From the older homes near the Emmaus Triangle to the newer subdivisions off Chestnut Street, we match the equipment to the house instead of selling one size for every job. Call 484-638-2837 to talk through a heat pump upgrade, a no-heat repair, or a tankless water heater for your Emmaus home.

Follow UsHeat pumps have become the practical choice for a lot of Emmaus homes because a single system handles both heating and cooling. Today's cold-climate models are built to keep producing heat well into a Lehigh Valley winter, and their efficiency means you often spend less to stay comfortable than you would running an older furnace and a separate AC. Our heat pump installation work starts with getting the size right, not with picking a box off a shelf.
Before we quote a system, we do a load calculation, often called a Manual J. In plain terms, that means we measure your home instead of guessing from its square footage. We look at how many windows you have, which way the house faces, how well it is insulated, and how much air leaks around doors and in the attic. A heat pump that is too big short-cycles, wears out sooner, and leaves rooms clammy. One that is too small runs constantly and never quite keeps up on the coldest nights. Getting the size correct is the single biggest thing that separates a heat pump you are happy with from one you regret.
A new heat pump can qualify for real money back. The federal 25C tax credit covers 30% of the cost of a qualifying heat pump, up to $2,000 per year, according to the IRS. On top of that, Pennsylvania utilities frequently run rebate programs on high-efficiency equipment. We help you sort out which systems qualify and hand you the paperwork you need, so the savings are not left on the table.
If your Emmaus home already has good ductwork, a ducted heat pump usually makes the most sense and keeps the look of the home unchanged. If your ducts are undersized, in rough shape, or missing entirely, a ductless system may be the smarter path. We walk both options with you and explain the trade-offs before you spend a dollar. When a system does act up down the road, our heat pump repair team knows these units inside and out.
A good share of Emmaus housing dates back decades, and many of those homes were built long before central ductwork was standard. Retrofitting ducts into a solid old house near the Triangle can mean tearing into plaster and losing closet space you cannot spare. A ductless mini-split solves that. The outdoor unit connects to slim indoor heads through a small line set, so there is no full duct network to install.
Mini-splits also let you set temperatures room by room. The bedrooms stay cool at night without over-cooling a living room nobody is using, and a converted attic or addition that the old system never reached finally gets comfortable. Because each zone runs only when you need it, you are not paying to condition empty space. We install ductless mini-split systems from names like Fujitsu and Mitsubishi, both of which build units that hold up through Pennsylvania winters. For an older Emmaus home without ducts, this is often the cleanest way to add real heating and cooling without a gut renovation.
Not every Emmaus home is ready to move off gas or oil heat, and that is fine. Plenty of families want a dependable furnace or boiler, and we install, service, and repair them all. If your furnace is short-cycling, blowing cool air, or making a noise it never used to, our furnace repair crew will diagnose it and explain the fix in language that actually makes sense.
Older borough homes with radiators or baseboard often run on a boiler, and those systems can last a long time when they are maintained. When a boiler starts losing pressure, running cold, or leaking around the circulator, our boiler repair team handles it. We also service oil furnaces and oil heat cleanings for homes that still run on oil. We work on AirEase, Heil, Concord, and Navien equipment, and we service all major brands, so you are not stuck just because your system is not the one we would have sold you.
Most heating breakdowns trace back to a part that was overdue for attention, which is why a yearly tune-up pays for itself. A maintenance plan keeps your furnace or boiler checked before the cold sets in, catches small problems while they are still cheap fixes, and moves you up the schedule when the busy season hits.
Summers in the Lehigh Valley get hot and sticky, and an AC that quits during a heat wave is more than an inconvenience. If your system is running but not cooling, freezing up, or tripping the breaker, our AC repair technicians will find the cause and get you cool again. We carry stocked trucks so a lot of common repairs get finished on the first visit.
When a system is past the point of another repair, we handle central air conditioning installation with the same sizing care we bring to heat pumps. A right-sized AC cools evenly, controls humidity, and does not run up your bill. We will show you efficient options from AirEase and Concord and give you honest guidance on when a repair makes more sense than a replacement, so you are not pushed into a new system before you need one.
If you are already thinking about replacing an aging AC, it is worth asking whether a heat pump makes more sense, since one system would then cover both your summer cooling and your winter heating. We are glad to price both side by side so you can see the difference before you decide.
Storms roll through the Lehigh Valley every year, and when the power goes out, a home without a backup can lose heat, refrigeration, well water, and sump protection all at once. We install Generac standby generators that switch on automatically when the utility drops, so your Emmaus home keeps running whether you are there or not. A standby unit sits permanently beside the house and runs on natural gas or propane, so there is no fuel to haul and no cords to run through a window. We size the unit to what you actually want to power, from the essentials to the whole house, and handle the full installation, including the transfer switch that decides which circuits stay live. For families with a well pump, medical equipment, or a home office that cannot afford downtime, it is peace of mind that pays off the first time a storm knocks out the block. Ask us about adding a standby generator when we are already out for HVAC work.
A tankless water heater heats water on demand instead of keeping a full tank hot all day, which means endless hot water and no standby loss from a tank sitting in the basement. For Emmaus homes tight on space or tired of running out mid-shower, it is a real upgrade, and a tankless unit typically lasts longer than a conventional tank while freeing up floor space. We install and service Navien tankless water heaters, a brand we trust for steady output and a long service life. Navien is our go-to for tankless in this area, and homeowners here consistently choose them for reliability.
If a tank still fits your home and budget better, we install and repair traditional tank water heaters, including dependable Bradford White units. Beyond water heaters, our plumbing services cover leak detection, fixture work, and repiping for Emmaus homes.
Serving Wescosville, too. This page also covers Wescosville, just north of the borough along Route 222. Wescosville homeowners call us for the same tankless and plumbing work, and we treat that stretch of Lower Macungie as part of our regular Emmaus route.
Geothermal is the most efficient way to heat and cool a home because it moves heat to and from the stable temperature of the ground instead of fighting the outside air. For Emmaus homeowners with the property to support a ground loop, it delivers low operating costs and a system that lasts for decades. The upfront investment is higher than a standard system, but the numbers change with incentives: the federal Residential Clean Energy Credit covers 30% of the cost of a qualifying geothermal system, per the IRS, with no dollar cap. Our geothermal installation team will tell you honestly whether your lot and home are a good fit before you commit.

Emmaus, ZIP 18049, sits in the southern Lehigh Valley with a walkable downtown built around the Emmaus Triangle, where Main Street's shops, cafes, and the local businesses give the borough its character. South Mountain rises along the southern edge of town, and the Emmaus Farmers' Market draws crowds through the warm months. The borough carries a real publishing heritage as the longtime home of Rodale, and families here are served by the East Penn School District.
Emmaus neighbors Wescosville to the north, Macungie to the west, and Upper Milford Township to the south, and we serve all of them. Whether you are in a century-old home near the Triangle or a newer build toward the township line, we bring the same care to every job. If you are just outside the borough, see our nearby service pages for Wescosville and Slatington.
