What we do
Heating and cooling, start to finish
Repairs, new installs and the seasonal maintenance that keeps a system from needing either.
Air Conditioning
Same-day diagnosis on a system that won't cool, and straight talk on whether a repair still makes sense or a new system is the better money.
- No cooling / blowing warm air
- Central AC repair
- New system installation
- Refrigerant leak diagnosis
Heating & Furnaces
Furnace and boiler repair and replacement for Philadelphia rowhomes — including the older gas and steam systems a lot of newer companies won't touch.
- No heat / short cycling
- Furnace repair & replacement
- Boiler service
- Pilot light & ignition issues
System Replacement
A full replacement is a big check to write. Yanni walks the actual house, explains the options in plain terms, and puts the price in writing before anything is ordered.
- Full HVAC system replacement
- Combined heating + cooling installs
- Equipment sized to the actual house
- Written pricing before ordering equipment
Ductless Mini-Splits
Heating and cooling for additions, converted attics, and rowhomes with no existing ductwork — one outdoor unit, one or several wall or ceiling heads.
- Single & multi-zone systems
- Additions & converted spaces
- Repair & maintenance
- Energy-efficient heating and cooling in one unit
Maintenance Plans
A seasonal check before the first heat wave or the first cold snap catches a small problem before it turns into a no-heat or no-cooling call.
- Spring AC tune-up
- Fall furnace tune-up
- Filter & coil cleaning
- Safety & efficiency check
Why Philadelphia calls Green Air
Rowhome heating and cooling isn't the same job as a suburban split-level.
Narrow rowhomes, no duct chases, ancient gas risers and steam boilers that pre-date central air by fifty years — Green Air works on the housing stock Philadelphia actually has, not the housing stock a national franchise trains for.
- Yanni diagnoses and quotes in person — no call-center estimate
- Ductless options for homes that were never ducted
- Services all major brands — Trane, Carrier, Lennox, York, Goodman and more
- Text a photo or a description before you commit to a visit
How it works
Call or text
Describe what the system is doing. Photos help.
Diagnose on site
Yanni looks at the actual equipment before quoting.
Fixed in writing
You get a clear price before any work starts.
Second opinion?
Already have a replacement quote from another company? Bring it to Yanni before you sign anything.
A 15-year-old system giving you trouble?
Repair it, or replace it?
There's no universal formula — it depends on the equipment's age, what the specific repair costs, and how often it's breaking down. Yanni will explain both sides honestly instead of defaulting to whichever one costs more.

Questions
Before you call
Do you charge for a diagnostic visit?
Ask when you call — this site doesn't publish a number until it's confirmed, so what you're told is accurate rather than guessed.
Can I text a photo instead of calling?
Yes — Yanni often gets a good sense of the problem from a photo or description before ever driving out, which can save you a wasted visit.
Do you work on older Philadelphia rowhomes with unusual systems?
That's a lot of the daily work — steam boilers, ancient gas risers, additions with no duct chase. It's a different job than a suburban split-level, and it's the one Green Air actually does.
Do you serve Delaware County too?
Yes — Springfield, Media, Broomall, Havertown, Drexel Hill, Upper Darby, Ridley Park and the surrounding area. See the Delaware County page for specifics.
Heat or AC acting up?
Call or text Yanni directly and describe what's going on. No call center, no dispatcher — you're talking to the owner.
