Heating and air conditioning service built around Radnor
Nobody in Radnor wants to spend a day waiting on a technician with a four-hour window. We quote a 90-120 minutes target response time for this ZIP and hold crews locally so that number is realistic.
Homes in Delaware County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Radnor43066 HVAC questions, answered
Do you offer maintenance plans?
We do. A two-visit plan in Ohio covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
How quickly can a technician get to Radnor?
For the 43066 service area our target response time is 90-120 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
What brands do you service in Radnor?
All of them. Our 43066 technicians are trained on Goodman, Daikin, Trane, Heil and essentially every other residential brand sold in Ohio, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Why is my furnace short cycling?
Short cycling in Radnor most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Do you service commercial and light commercial properties?
Yes. Around Radnor we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
