Wyomissing is one of the older, more established communities in Berks County, and its homes ask a lot of a heating and cooling system. You will find 1920s planned-community houses with original boilers and radiators, mid-century homes that had forced-air heat and central cooling added later, and larger properties in Wyomissing Hills and Berkshire Heights running zoned equipment. DeLong & Sons HVAC is a family-owned company that handles all of it - furnace and boiler repair, air conditioning, heat pumps, generators, geothermal, and plumbing - for homeowners across Wyomissing, PA and the Reading area.
We are based just up the road in Shoemakersville, which means a local crew answers your call rather than a regional dispatch center. You get upfront pricing before any work starts, over 15 years of experience on every visit, and same-day service Monday through Friday when something quits. After-hours emergency service is available for an additional fee. Call 484-638-2837 and we will get you on the schedule.

Follow UsHeating is where Wyomissing homes vary the most. Many of the original 1920s planned-community houses were built around hot-water or steam boilers feeding cast-iron radiators, and a good number still run that way. Others had forced-air furnaces retrofitted in over the decades, sometimes squeezed into a converted coal-chute space or a tight basement corner. And it is common to find additions and finished attics heated by a second, mismatched system that never quite kept up with the rest of the house.
That history shapes how we work here. When a furnace stops heating on a cold morning, our technicians diagnose the actual fault - a failed ignitor or flame sensor, a bad control board, a clogged filter starving airflow - and give you a straight answer before any repair begins. See our furnace repair service for what a visit covers.
When a system is past the point of paying to fix, we help you weigh a furnace installation against the layout you actually have. In the larger homes across Wyomissing Hills and Berkshire Heights, that often means sizing a zoned system correctly so the upstairs is not roasting while the first floor stays cold. We install AireEase, Heil, and Concord equipment and service all major brands.
For the radiator and hot-water heat still common in the borough, our boiler repair service covers no-heat calls, failed circulators, low-pressure faults, and the leaks that show up in older near-boiler piping. We keep boiler systems running rather than pushing you toward a tear-out you do not need.
Cooling an older Wyomissing home is its own challenge. Houses that started with boiler heat have no ductwork to share, so central air was almost always added later - sometimes with a high-velocity system, sometimes with an outdoor condenser tied into ductwork that was retrofitted through closets and soffits. Those retrofit setups work well when they are sized and sealed properly, and they cause comfort complaints when they are not.
When your air conditioner stops keeping up during a Berks County heat wave, our AC repair service covers weak airflow, a system that runs but will not cool, refrigerant problems, and a frozen coil. We diagnose the cause instead of just topping off refrigerant and moving on.
If your system is aging out or was never a good match for the house, our air conditioning installation service helps you pick equipment that fits your ductwork and your home's real cooling load. In a two-story or three-story Wyomissing home, that often means addressing why the second floor never cooled well in the first place, whether that calls for a zoned setup, better return airflow, or a dedicated system for the upper level.
For homes where running new ductwork is not practical, a ductless system is often the smarter path, which we cover below. Either way, we would rather size the job to your house than sell you the biggest unit on the truck - an oversized air conditioner short-cycles, leaves the air clammy, and wears out faster than one that is matched correctly.
More Wyomissing homeowners are moving toward electric heating and cooling, and a heat pump is often the centerpiece. A single system handles both jobs, and today's cold-climate models hold their output well into a Pennsylvania winter. Federal tax credits and utility rebates can offset a meaningful share of the upgrade cost, which makes the math work better than it did a few years ago. Our heat pump installation service walks you through the options and the incentives that apply to your project.
For the boiler-heated homes with no ductwork, a ductless mini-split installation is often the cleanest way to add cooling and supplemental heat. A ductless system puts a quiet indoor head exactly where you need it - a converted attic bedroom, a sunroom addition, a finished basement - without tearing into finished walls. We install Fujitsu and Mitsubishi ductless equipment and size each zone to the room it serves.
Because a heat pump is only as good as its installation, we take the time to get the details right: proper line-set routing, a level condenser pad, and a controls setup you can actually understand. Done well, a heat pump keeps a Wyomissing home comfortable through both the humid summers and the cold snaps, on a single system that costs less to run than the electric-resistance backup it replaces.
When a storm knocks out power, a standby generator keeps the furnace, the sump pump, the refrigerator, and the well running while the rest of the block waits it out. For the larger homes in Wyomissing Hills and Berkshire Heights, that resilience matters, especially when heat or a sump pump is what stands between you and a frozen or flooded basement.
We install Generac standby generators sized to the loads you actually want to protect, wired to a transfer switch that brings your circuits back automatically. Our whole-home generator service covers the sizing, the install, and the ongoing service that keeps the unit ready to run when you need it.
For homeowners planning to stay put and interested in the lowest long-term operating cost, geothermal is worth a look. A ground-source heat pump uses the stable temperature below your yard to heat and cool the house, and it does both from one system with no outdoor condenser to look at or listen to. The upfront cost is higher than a conventional system, but a 30% federal tax credit on qualifying geothermal installations takes a real bite out of that difference.
Geothermal suits the larger lots you find in parts of Wyomissing better than a tight in-town parcel, so the first step is always a look at your property and your heating and cooling loads. Our geothermal installation service starts with that assessment before anyone talks about equipment.
The same building history that shapes Wyomissing's heating also shows up in its plumbing. Many of the borough's older homes were plumbed with galvanized steel supply lines and cast-iron drains, materials that corrode and clog from the inside over decades. That is why an older Wyomissing house can have good water pressure at the meter but weak flow at the tap, or slow drains that keep coming back no matter how many times they are snaked.
Our plumbing services cover the day-to-day - leak detection and repair, fixture installations, and failing supply lines - with an eye to what the house is actually built from. When aging galvanized pipe is the root cause, we will tell you plainly rather than chasing symptoms one leak at a time.
Water heaters are one of the most common calls we get here. For a traditional tank, our tank water heater service handles no-hot-water diagnostics, replacements, and installs, and we install dependable Bradford White units. If you want endless hot water and a smaller footprint, our tankless water heater service installs and services Navien tankless systems, which are a good fit for homes that have outgrown a single tank.
Wyomissing's commercial spine runs along Penn Avenue and out toward the Knitting Mills redevelopment, where offices, shops, and restaurants all depend on equipment that cannot afford a long outage. A rooftop unit that quits in July or a heating system that fails on a Monday morning costs a business real money for every hour it is down.
Our commercial HVAC service covers rooftop units, commercial furnaces and boilers, and the design and installation work behind a new or expanded space. We keep the workday moving with the same upfront pricing and local response we give homeowners, and we can set up a maintenance schedule that catches problems before they close your doors.
Whether you run a storefront on Penn Avenue, an office suite, or a space in one of the repurposed mill buildings, we size the fix or the replacement to your building rather than a generic template. Scheduled service is usually the difference between a planned tune-up and an emergency call in the middle of your busiest week.
DeLong & Sons HVAC is a family business built by Justin DeLong and run with the whole family involved. In a market with plenty of big Reading-area outfits to choose from, homeowners keep our number because they get the same crew each visit, a real person who explains the problem in plain language, and upfront pricing with no surprises at the end.
We were named a 2024 Nextdoor Neighborhood Fave and recognized as a Housecall Pro Super Pro, and you can read what your neighbors say on our reviews page. When something quits and you cannot wait, our same-day service gets a technician to your Wyomissing home Monday through Friday whenever we can, with after-hours emergency service available for an additional fee. Booking is simple through our online Housecall Pro scheduler or a quick call to the office.
The cheapest repair is the one you never have to make. Our maintenance plans keep your heating and cooling equipment tuned twice a year - cooling in the spring, heating in the fall - so small problems get caught before they leave you without heat in January. Plan members also get priority scheduling, which moves you to the front of the line during the busy stretches when calls stack up. For the older equipment common in Wyomissing homes, regular service is often what stretches a system a few more good years.
Wyomissing (ZIP 19610) is one of Pennsylvania's early planned garden suburbs, laid out in the 1920s with curving streets, generous setbacks, and a public park system built into the plan. The Wyomissing Park system and Wyomissing Creek still run through the heart of the borough, and the old textile plants at the Knitting Mills - long home to the VF Outlet before its redevelopment - remain a landmark on the commercial side of town.
Wyomissing sits right against West Reading and the Reading Hospital campus, and its Penn Avenue corridor anchors much of the area's shopping and dining. Families here are served by the Wilson School District, and neighborhoods like Wyomissing Hills and Berkshire Heights hold some of the larger, more established homes in Berks County. That mix of 1920s housing stock and newer construction is exactly why the borough needs a contractor comfortable with both.
All of that history adds up to a housing stock unlike most of Berks County: careful 1920s architecture, decades of retrofits layered on top, and newer construction filling in around it. A contractor who only knows new builds gets tripped up here, and one who only knows old homes cannot serve the newer neighborhoods. We work across the whole range, which is why so many Wyomissing families keep our number on the fridge.
We serve the surrounding communities too, including nearby Sinking Spring and Wernersville just west along the Penn Avenue line.
From furnace and boiler repair to air conditioning, heat pumps, generators, geothermal, and plumbing, DeLong & Sons HVAC handles the full range of comfort work for Wyomissing homes and businesses. Whether you need a fast repair or a system replacement sized to your home, our family crew is ready to help.
Call before 6 PM on a weekday for same-day service when we can manage it. After-hours emergency service is available for an additional fee.
