HVAC in Horsham, PA | Heating & Cooling

A Local Family Shop Since 1946

W.F. Smith is a family-owned heating and cooling company that serves Horsham Township, PA. We install, fix, and take care of heating and cooling for homes across 19044 and the nearby Montgomery County suburbs. Our shop has been on State Road in Northeast Philadelphia since 1946.

Our office tells you the visit fee before we come out, and estimates for new systems are free. We work on air conditioners, furnaces, heat pumps, ductless systems, ducts, and indoor air quality. We do not work on boilers, water heaters, oil systems, or steam systems.

Most of our new systems use Lennox or Mitsubishi Electric. Our technicians also fix other big brands, and every new system starts by measuring your home first.

Horsham is the one main area we serve that sits in Montgomery County instead of Bucks County. The real difference is who gives out the permits here, since it is a different town with its own rules. The other difference is the homes themselves. Older mid-1900s neighborhoods, homes from the 1980s and 1990s, and newer homes built near the old naval air base all sit in the same township.

Common HVAC Problems in Horsham Homes

Horsham has a bigger mix of old and new homes than most townships its size. An older home loses air easily and loses heat or cooling to its far rooms. A newer home barely leaks air at all and has trouble getting rid of extra moisture.

What we get called for most:

A new home that cools fast but still feels damp. A tightly sealed home needs much less cooling than an older one. Equipment sized the old-fashioned way cools the air fast, turns off, and never runs long enough to pull the wet air out.
A mid-1900s home that cannot cool or heat its far rooms. The original ducts, the original insulation, and a system sized by an old chart can leave the far rooms behind in both summer and winter.
Stale air in a tightly sealed home. Cooking smells, moisture, and fine dust stay trapped inside unless the home has real ventilation and filtering built in.
Two homes the same size needing very different-sized systems. An older ranch home and a newer home do not need the same amount of cooling or heating. Only measuring the home tells you the real size needed.
Whole neighborhoods needing new systems at the same time. Streets built within a year or two of each other got their systems put in around the same time, so those systems can all turn 20 years old together.

Air conditioning

Air conditioning in Horsham is mostly about getting the size right, and it goes wrong in both directions. Newer township homes often get a system that is too big, while mid-1900s homes often have ducts too small for whatever system they have. We fix, replace, install, and take care of central air conditioners across the township. Common calls are warm air at the vents, a frozen coil, a refrigerant leak, and an outdoor unit that will not turn on.
When we replace a system, we measure your home to find the right size instead of just copying the old size. In a home built to today’s energy rules, the honest answer is often a smaller system than the old one. Running longer at a lower setting is what pulls the moisture out of the air.

Heating and furnaces

Furnace work in Horsham depends a lot on when the home was built. Mid-1900s homes have often gone through two or three furnaces, and each new one had to fit in a space built for the very first one. That can leave tight spaces, filter slots that are hard to reach, and vents that were adjusted rather than built right the first time.
Newer Horsham homes usually vent an efficient furnace through a side wall using plastic pipe. Common problems there are a blocked drain trap, a clogged intake screen, or a safety switch correctly telling us there is a vent problem.
In both older and newer homes, most no-heat calls come from a problem starting the flame, a broken flame sensor, a bad thermostat, or a dirty filter. A technician checks each step the furnace goes through to find where it stops.
We do not work on boilers, steam systems, or oil heating.

Heat pumps and dual-fuel

Horsham is a good area for heat pumps, and the newer half of the township is even better than most. A tightly sealed, well-insulated home needs so little heat that a heat pump alone can keep it warm all winter. New heat pumps still work well even when it is well below freezing outside.
For a home with a working gas furnace, we can add a heat pump that switches to gas once it gets cold enough outside. This is often the cheaper way to get most of the benefit. Rebates from the Electrical Association of Philadelphia and from the equipment makers often apply.

Ductless mini-splits

Ductless systems are worth it in Horsham for rooms your main system was never built to reach. A converted garage, a finished basement, a home office, or an added sunroom all qualify. These rooms sit too far away to get good airflow from the main ducts. A ductless unit gives one of these rooms its own thermostat, without touching the rest of the house.
Mitsubishi Electric is the brand we install most here. One outdoor unit feeds each indoor unit through a small hole in the wall, so there is no need to build boxes around pipes or lose a closet. In newer homes, a ductless unit also works well for a finished third floor or an extra room the builder left on the main system.

After-Hours Emergency Service

Emergency calls in Horsham can come in waves. Streets built within the same two or three years can have all their equipment wear out around the same time, so one cold snap can cause problems for a whole neighborhood at once.

W.F. Smith offers after-hours help for emergencies. We do not run regular service around the clock. Our office answers calls Monday through Friday, 8:00 a.m. to 4:00 p.m. Outside those hours, an answering service will reach the technician who is on call. After-hours and Saturday visits cost more. Sundays and holidays cost even more, and the technician tells you the price before heading out.

Customers with a maintenance plan get seen first when a week like that happens.

Ductwork, air quality, and maintenance

Once your main system is settled, three other things often come up. In Horsham, the second one matters more than it does elsewhere:

Custom ductwork

Fixing a mid-1900s home’s air return path means building new ducts, not just adding a vent cover. We build to fit the exact space your home has.

Indoor air quality

A tightly sealed newer home needs real ventilation and real filtering, because it cannot clear out stale air on its own.

Maintenance

Spring and fall check-ups catch problems early. On a street where every system is the same age, a check-up can tell you which year yours is likely to need replacing.

Ask about a maintenance visit before the season turns

Why Horsham Is Harder on HVAC Than the Rest of Our Territory

Most of what W.F. Smith does is in Bucks County. Horsham is in Montgomery County, and that shows up in the paperwork, not the weather. Four things make it different.

Four things drive the difference:

A different permit office. Home heating and cooling work in Horsham goes through the township, not a Bucks County town. The forms and wait times are different, so we check the current rules before scheduling an install.
Two very different ages of homes in one township. Mid-1900s neighborhoods and newer homes share the same ZIP code. Two homes the same size can need very different-sized systems, so we measure instead of guessing.
New building on the old air base land. The naval air base closed in 2011, and the land has been getting rebuilt ever since. Homes near that land are built to today’s codes, which means they are sealed very tightly.
Whole streets of equipment wearing out at once. Neighborhood streets built in one season often need their systems replaced around the same time too. Knowing which streets are due changes how we plan spring check-ups.

Wet summer air is the constant problem underneath all of this. Montgomery County summers stay sticky enough that a system that is too big can leave a home cool and damp at the same time.

Horsham Neighborhoods We Serve

We cover the whole township, and a few areas keep us busiest.

We also cover Philadelphia and more than 20 other communities across Bucks and Montgomery Counties, plus Lambertville, New Jersey.

Central Horsham along Horsham Road (19044).

Older mid-1900s neighborhoods where fixing the ducts matters more than the equipment itself.

The Easton Road area (19044).

A mix of homes from different decades along one road, so the right fix changes house by house.

The Welsh Road side (19044).

Newer neighborhood homes where systems tend to need replacing in groups.

The old naval air base land and streets around it (19044).

Newer, tightly built homes, where getting the size and ventilation right matters more than just having a bigger system.

The Hatboro line (19044).

Smaller, older homes on tighter lots, where we figure out space for the outdoor unit first.

The Maple Glen and Dresher edge.

Bigger properties, often with two systems or separate controls for different parts of the home.

The County Line Road area.

The Bucks County line runs right along it, so neighbors just a block apart can need permits from two different towns.

Our Experience in Horsham Homes

W.F. Smith has worked in Montgomery County homes since 1946. The Smith family still owns and runs the company. Our five owners have more than 140 years of work experience between them, and our main technicians have worked here for over 20 years each on average.

We hold Pennsylvania Home Improvement Contractor license PA003700 and have been accredited by the BBB since 1991. Parts on repair work come with a one-year warranty.

In Horsham, that long history mostly shows up as restraint, since our crew has measured enough newer homes to know the honest answer is often a smaller system, not a bigger one. It also shows up in the ducts, where fixing a mid-1900s air return path takes longer than swapping an outdoor unit, but often solves more complaints.

Why Horsham Homeowners Call W.F. Smith

Size set by measuring, not by the old system's label.

In a home built to today’s codes, measuring often shows that a smaller system is right, not a bigger one. We quote what the numbers say.

Permits handled through the right office.

Horsham is in Montgomery County, so we check the township’s current permit rules before scheduling your job.

Wet air treated as something to fix, not ignore.

Run time and airflow get set so a tightly sealed Horsham home comes out feeling dry as well as cool.

A heads-up before your whole street's systems quit.

When a neighborhood’s systems tend to go out in groups, we would rather tell you your system is getting old in April than have it break down in July.

HVAC Questions From Horsham Homeowners

Why does my newer Horsham house feel clammy even when the AC runs?

Because the unit is almost certainly too big for the house. A home built to today’s energy codes leaks far less air, so it needs much less cooling than the same size home would have needed decades ago. A system that is too big hits the thermostat setting in a few minutes and shuts off before it has pulled out much moisture. The fix is a correctly sized system, or one that runs longer at a lower setting.

Does being in Montgomery County change anything about the work?

It changes the paperwork more than the actual work. Horsham Township handles home heating and cooling permits and inspections for 19044, not a Bucks County town. The forms, fees, and inspection scheduling follow a different process, so we check the current rules before setting an install date. The equipment, the sizing, and the warranty handling are the same as on any job we do.

My mid-century Horsham house never cools the back rooms. Is the AC too small?

Usually not. In a mid-1900s home, the real limit is almost always the ducts, not the air conditioner. The original ducts were sized for a heating system moving warm air, and there are rarely enough return vents for cooling. Putting in a bigger air conditioner just pushes more air into the same too-small ducts and makes it louder without actually reaching the far rooms. Testing the airflow shows which problem you really have.

Everyone on my street is replacing their system. Should I get ahead of it?

It is often worth checking. Horsham neighborhood streets were frequently built within one or two seasons, so their original systems all went in around the same time and can reach 15 to 20 years old together. A spring check-up tells you if yours is near the end, which gives you time over the winter to plan and pick your own install date.

How does after-hours service work in Horsham?

The office answers Monday through Friday, 8:00 a.m. to 4:00 p.m. After those hours, an answering service reaches the technician on call, who calls back and tells you the price before leaving the shop. Customers with a maintenance plan get seen first, which matters in Horsham since systems on one street can fail in the same week.

Can a heat pump heat a Horsham house through winter on its own?

In a reasonably well-sealed home, often yes. New heat pumps still work well even when it is well below freezing outside, and Horsham winters rarely stay that cold for long. The home matters more than the equipment. A newer home with good insulation is a good fit, while a leakier, older home may want to keep a gas furnace as a backup.

Why does my new house smell stuffy when the old one never did?

A new home is sealed so tightly that it no longer airs itself out on its own. Cooking smells, cleaning product fumes, pet dander, and fine dust used to leak out through gaps that a newer home simply does not have. The answer is real ventilation plus real filtering, not an air freshener. A whole-house air purifier, a better filter, and a system that brings in fresh air all work together to fix it.

Comfort Problems Are Not Always Equipment Problems

In larger Horsham homes, uneven temperatures can come from duct design, additions, airflow, or equipment sizing just as easily as from a failed part. W.F. Smith customers often mention technicians who listen to the comfort complaint first and explain the available options clearly before work starts.
