Air Conditioning Installation in Wynnewood, PA
Adding or replacing air conditioning in Wynnewood is more of a design decision than an equipment purchase, because a great many homes here were built with radiators and have no ductwork to work with. The question is not which brand — it is which of three approaches suits the building.
PJ MAC installs all three from our Bryn Mawr office on West Lancaster Avenue. Estimates are free and we are not a single-manufacturer dealer, so the recommendation is not shaped by a dealer agreement.
The three approaches, honestly compared
Conventional ducted
Where there is existing duct, or where chases and closets allow new duct to be run, this is usually the best value and the quietest option. The cost is space: in a house with no ductwork it typically means surrendering closet depth on every floor, and in a home with original plaster and millwork the disruption is real.
High-velocity small-duct
Flexible tubing runs through joist bays and wall cavities that conventional duct cannot reach, terminating in small round outlets. It preserves plaster, moulding and room proportions, which is why it is common in Lower Merion. It costs more than conventional duct, moves air at higher velocity so outlet placement matters, and it is less forgiving of a poorly executed installation.
Ductless mini-splits
No duct at all, zoned by nature, and the least invasive. The trade-off is visible indoor heads and one outdoor unit serving them. Frequently the right answer for a converted third floor, an addition, or a single room that has never been comfortable — and sometimes for a whole house where the alternatives would gut it.
Sizing in a masonry house
Thick stone and brick walls behave differently from frame construction. They absorb heat through the day and release it into the evening, which means the peak cooling load arrives later and the building holds temperature longer once conditioned.
This is exactly the situation where oversizing does the most damage. An oversized system satisfies the thermostat quickly, shuts off before it has removed humidity, and leaves a house that is cold and clammy — in a masonry home that never needed the extra capacity in the first place. We size from a load calculation on the actual building rather than matching whatever was there.
If you have a boiler, keep it
Homeowners adding cooling frequently ask whether they should abandon the radiators and put in a forced-air furnace at the same time, so everything runs on one system. Usually the answer is no. A sound cast iron boiler with hydronic distribution delivers comfortable, even heat, and replacing it with forced air to save on a second system rarely pays back — you would be scrapping working equipment and adding duct load the cooling design does not need.
We will tell you when the boiler genuinely is at the end of its life. We will not tell you that just because you are already spending money.
What the estimate covers
- ✓A load calculation on the building, accounting for masonry mass, glazing and orientation
- ✓An honest comparison of conventional, high-velocity and ductless for your specific house
- ✓Where duct is involved, an assessment of what can be run without disturbing finished surfaces
- ✓Condenser placement reviewed for clearance, airflow and noise to neighbouring properties
- ✓Removal and disposal of any equipment being replaced
- ✓A clear written scope so competing quotes can be compared on the same basis
Wynnewood AC Installation — Questions We Get
My house has radiators and no ductwork. What are my options?
Three: conventional duct where chases and closets allow it, high-velocity small-duct which threads flexible tubing through joist bays and preserves plaster and moulding, or ductless mini-splits which need no duct at all. Each has real trade-offs and we will compare them for your specific house rather than defaulting to one.
Is high-velocity worth the extra cost over conventional duct?
In a house with original plaster, moulding and tight proportions, often yes — it reaches places conventional duct cannot without surrendering closet space on every floor. In a house where conventional duct can be run cleanly, conventional is usually better value and quieter.
Should I replace my boiler with a furnace while I am adding air conditioning?
Usually not. A sound cast iron boiler gives even, comfortable heat, and scrapping working equipment to consolidate onto one system rarely pays back. We will tell you if the boiler genuinely is near end of life, but not simply because you are already spending money.
Does a stone house need a bigger system?
Generally the opposite. Masonry absorbs heat through the day and releases it later, so the load peaks later and the building holds temperature once conditioned. Oversizing does particular damage here — the system satisfies quickly, shuts off before removing humidity, and leaves the house cold and clammy.
Will you match the size of my existing system?
No. We run a load calculation on the actual building, because the existing system may well have been oversized and matching it would carry that mistake forward.
Are estimates free?
Yes, on installation work. You get a written scope so you can compare quotes on the same basis rather than guessing what each includes.
