Delaware Valley Air Conditioning & Heating has been the go-to heating and cooling company for Drexel Hill homeowners, landlords, property managers, and businesses since 2010. We handle the full range of residential and commercial HVAC work: AC repair, furnace repair, heat pump service, ductless mini-split installation, boiler service, system replacement, and everything in between. Whether your air conditioner stops on the hottest day of July or your furnace quits on a cold January night, we have you covered. Trusted by local homeowners and property managers for their heating and cooling, we keep Delaware County comfortable year-round.
Family-owned. Locally rooted. Comfort is our business.
Good HVAC work isn't complicated, it's just done right, and that starts with knowing exactly what your system needs. We offer a complete range of heating and cooling services for homes and commercial properties across the area. Here is what we handle:
Your air conditioner is not cooling, not turning on, or running constantly without keeping up. We diagnose the problem at the source: evaporator coil issues, refrigerant leaks, condenser and compressor problems, and airflow restrictions that cause uneven temperatures room to room. We get the system working again.
A furnace that won't turn on, blows cold air, or short-cycles is more than an inconvenience in a Pennsylvania winter. We repair oil and gas furnaces, inspect heat exchangers, and service blower motors and controls. If the heat is not right, we find out why.
Heat pumps are year-round systems, and when something goes wrong, it affects both heating and cooling. We handle refrigerant issues, reversing valve problems, and full heat pump diagnostics for Drexel Hill's mixed-season climate.
When a repair no longer makes sense, we replace the system. New AC unit, new furnace, full HVAC system replacement. We walk you through the options with straight answers and up-front pricing before any work begins. Call for a quote and we will tell you exactly what you are looking at.
A programmable or smart thermostat can make a real difference in comfort and energy use. We install and configure thermostats, sort out wiring issues, and replace thermostats that have stopped responding correctly.
Leaking or poorly sealed ductwork is one of the most common causes of uneven temperatures and higher energy bills. We inspect, repair, and seal ductwork so conditioned air actually reaches the rooms it is supposed to reach.
Whole-home air purifiers, UV air purifiers, air scrubbers, and HVAC filter upgrades all help reduce dust, allergens, and airborne contaminants. We also install whole-home humidifiers, a practical addition in Pennsylvania's cold, dry winters when indoor air can get uncomfortably dry.
A spring AC tune-up and a fall heating tune-up keep your system running efficiently and catch small problems before they become expensive ones. Work is performed by qualified HVAC technicians, and we stand behind every system we service.
Call us and we'll handle the rest.
Staying ahead of HVAC problems keeps your home comfortable, but sometimes a system fails without warning. No heat in the middle of winter. No air conditioning during a heat wave. A system that shuts down mid-day with no obvious cause. These are not situations where you want to wait a week for an appointment.
We offer same-day availability and after-hours response for urgent heating and cooling problems across Delaware County. We show up on time and ready to work, with the tools and parts on hand to handle most repairs in a single visit. If your system is down, call us and we will get someone out to you.
Pick up the phone and we'll get started.
Delaware County's housing stock is older than most, and the heating systems that come with it reflect that history. Many homes in and around Drexel Hill still run on boilers, steam and hot-water radiators, and oil heat. The Northeast accounts for roughly 79 percent of the country's oil-heated homes, and Pennsylvania carries a significant share of that. At the same time, humid summers and many homes without existing ductwork have made ductless cooling a practical solution throughout the area. These three services come up constantly in our work here.
Many older Delaware County homes heat with hot-water boiler systems, and these systems need qualified attention when they stop performing. A boiler visit typically covers burner inspection, zone valve service, system pressure checks, and hydronic balancing to make sure heat reaches every room evenly. When a boiler is short-cycling, losing pressure, or leaving certain zones cold, we find the cause and restore reliable heat. We also perform seasonal boiler tune-ups to keep systems running safely through the winter.
A large number of homes in this area still rely on oil heat, and many owners are ready to move on. Converting to natural gas or upgrading to a heat pump is one of the most common projects we handle. A heat pump conversion is particularly practical here because it handles both heating and cooling in a single system, which matters in a region with real winters and humid summers. We manage the equipment side of the conversion, coordinate the process clearly, and make sure the new system is set up correctly from day one.
Older homes without ductwork, room additions, converted attics or basements, and detached garages all present the same challenge: how do you condition a space without tearing walls apart to run ducts? A ductless mini-split is the right answer for most of these situations. We assess the space, size the equipment correctly, and install the system cleanly. The result is reliable heating and cooling right where you need it.
We'll get the job done and the system running.
Property managers and business owners need HVAC work handled efficiently and without disruption. We work with office buildings, retail spaces, and restaurants across the area on commercial AC repair, commercial heating repair, rooftop unit service and replacement, and ongoing commercial HVAC maintenance. When something goes wrong with your system, you need straight answers about your furnace, AC, and ductwork, no surprises. That is what we bring to every commercial job.
Pick up the phone and we'll handle the system.
We're your neighbors, and your comfort is personal to us. When you call, you reach someone who knows this area, knows the homes here, and understands what Delaware County winters and summers actually feel like. The same people who answer the phone are the ones who show up at your door.
We have been doing this work in Drexel Hill and the surrounding communities since 2010. Every job gets our full attention, whether it is a tune-up on an older boiler or a full system replacement in a home that has never had central air. Work is performed by qualified HVAC technicians who take the job seriously and leave your home clean and comfortable when they are done.
We find the fault. We make the repair. We restore the comfort.
Drexel Hill is our home base, and we serve customers throughout Delaware County and the surrounding area. If you are nearby, we can help.
We work with residential homeowners, landlords, property managers, and small commercial clients throughout Delaware County. Whether you need a single service call on a rental unit or ongoing HVAC support across a portfolio of properties, we handle both. Call (484) 465-3289 and we can talk through what your situation requires.
When you call, a real person picks up and gathers the basic details about your system and what it is doing. We schedule a visit, same-day when available, and a qualified HVAC technician arrives on time with the tools for the job. Before any work begins, we explain what we found and what the repair or replacement will involve, so you know exactly what you are agreeing to.
Yes. We handle Saturday and Sunday calls the same way we handle weekday calls. If your system goes down over a weekend, call (484) 465-3289 and we will get someone out to you.
If the repair cost is approaching half the value of the equipment and the system is more than 10 to 15 years old, replacement usually makes more sense on cost and long-term comfort. We walk you through both options honestly so you can make a confident decision. We will never push a replacement when a repair is the right call.
It helps to know your system type if you can, whether it is a furnace, boiler, heat pump, or central AC, and to describe what the system is doing or not doing. If you have the equipment brand or age handy, that is useful too. If you do not have any of that, just call and describe the problem and we will take it from there.
The scope of the work, the equipment involved, and the condition of your existing system all factor into the final cost. If something unexpected comes up once we are into a job, we stop and talk to you before moving forward. We do not change the number on you after the fact.
We give you a clear number before work begins, and what we tell you is what you pay. If the job turns out to involve something we could not see until we opened the system, we explain it and get your approval before continuing. There are no surprise charges at the end of a visit.
Payment is due when the work is complete and you are satisfied with the result. We go over the invoice with you before we leave so there are no questions about what was done or what you owe.

How do I know if my system needs a repair or a full replacement?
A few factors point toward replacement: the system is more than 10 to 15 years old, the repair cost is approaching half the value of the equipment, or the same components keep failing. We walk you through both options honestly so you can make a confident decision. We will not push a replacement when a repair is the right call.
What are the signs that my AC or furnace is starting to fail?
Common signs include a system that short-cycles, runs constantly without reaching the set temperature, makes unusual noises, or produces uneven temperatures from room to room. Higher-than-normal energy bills without a change in usage can also signal a system that is working harder than it should. If you notice any of these, it is worth having a technician take a look before a small problem becomes a larger one.
Why is one room always hotter or colder than the rest of the house?
Uneven temperatures usually point to one of three things: a duct leak or restriction that is starving certain rooms of conditioned air, an equipment sizing issue, or a zone control problem. We diagnose the actual cause rather than guessing, and we explain what we find before any work begins.
Same-Day and Emergency Availability
When your heat goes out in January or your AC fails in July, waiting is not an option. We offer same-day availability and after-hours response for urgent heating and cooling situations across Delaware County.
How often should I schedule maintenance and tune-ups?
Twice a year is the standard: a spring tune-up before cooling season and a fall tune-up before heating season. Each visit covers filters, coils, burners or refrigerant levels, and safety checks depending on the equipment. Staying on that schedule catches small problems early and keeps the system running efficiently through the season.
What does a seasonal tune-up actually cover?
A tune-up is not just a filter swap. For a furnace or boiler, it includes burner inspection, heat exchanger or combustion checks, blower or pump service, and a safety review. For an AC or heat pump, it covers coil cleaning, refrigerant level checks, electrical connections, and airflow testing. Work is performed by qualified HVAC technicians who document what they find.
What causes a system to short-cycle?
Short-cycling, where the system turns on and off more frequently than it should, can come from an oversized unit, a dirty filter or coil restricting airflow, a refrigerant issue, or a control or thermostat problem. It puts extra wear on the equipment and reduces comfort. We diagnose the root cause rather than treating the symptom.
Upfront Quotes With No Surprise Fees
We give you a clear number before any work begins. If something unexpected comes up once we are into the job, we explain it and get your approval before continuing. What we quote is what you pay.
Do I need to be home when the technician arrives?
Someone does need to be available to provide access to the equipment and to review the findings before work begins. If you cannot be there in person, we can work with a property manager or another adult who has access and can authorize the work. Just let us know when you call.
How does your pricing and quoting process work?
We give you a clear number before work begins. If something unexpected comes up once we are into a job, we stop and explain it before moving forward. There are no charges added after the fact. What we tell you before the work is what you pay when it is done.
Experienced With Older and Newer Systems
Delaware County's housing stock runs the range from century-old homes with boiler heat to newer construction with modern heat pumps. We are familiar with both ends of that spectrum and everything in between.
What should I know about converting from oil heat to a heat pump or gas system?
Oil-to-gas and oil-to-heat-pump conversions are among the most common projects we handle in this area. A heat pump is particularly practical here because it handles both heating and cooling in one system. We manage the equipment side of the conversion, size the new system correctly for the home, and make sure everything is set up right from day one.
Can you cool or heat a space that does not have existing ductwork?
Yes. A ductless mini-split is designed for exactly that situation. Older homes, room additions, converted attics, and detached garages are all common candidates. We assess the space, size the equipment for it, and install the system without opening walls to run ducts. The result is reliable heating and cooling right where you need it.
What do strange noises from my HVAC system usually mean?
Banging or clanking often points to a loose or failing mechanical component. Squealing can indicate a belt or motor bearing issue. Rattling sometimes means debris in the system or a loose panel. Gurgling in a boiler or hydronic system can signal air in the lines or a pressure issue. None of these should be ignored; a technician can usually identify the source quickly.
