Heating, cooling and commercial refrigeration for homes and businesses across Kent and New Castle County. Same-day repairs, fully stocked trucks, and a real technician on the phone at 2 a.m. — not a call center reading from a script.
Three taps and we'll route you to the right tech. No account, no hold music.
We'll text you shortly to confirm your window. Need us sooner? Call the 24-hour line and we'll move you up.
Call 302-515-0777So we don't treat them the same. Home repairs get scheduled around your day — usually the same day. Critical cooling gets priority dispatch, because every hour costs you product, uptime or a health inspection.
Repairs, replacements and tune-ups for houses from Smyrna to Middletown and Dover.
Refrigeration and commercial HVAC for kitchens, retail, labs and equipment rooms.
You're probably comparing options right now. That's smart. Here's what actually separates a same-day fix from a week of waiting.
Every technician rolls up in a fully stocked truck with parts and the latest tools, so most repairs finish on the first visit — the same day you call.
Blowing warm, short cycling, frozen coil or tripping the breaker — we diagnose it, price it before we start, and fix it.

Read all 40 reviews →★★★★★A sudden AC problem on a weekday: their tech arrived in just a few hours, and fixed the problem. Fair rates, personable office staff, and a new HVAC company for good.
Based in Smyrna, Delaware, covering Kent County and New Castle County — north to Wilmington, south to Dover. Not sure if you're in range? Call. Usually the answer is yes.
Systems fail on the hottest and coldest days, never on payday. We offer approved financing on qualifying installs, so you can pick the right equipment instead of the cheapest one.
Ask about financing →Most repair calls, yes — we hold slots open every day for them. Call early and you'll usually get a window that afternoon. Emergencies get moved to the front of the line day or night.
Yes. The 24-hour line reaches an on-call technician, not a voicemail box. No-heat calls in winter and refrigeration failures any time of year get dispatched.
We quote the diagnostic fee on the phone before we roll, and you approve the repair price before any work starts. You'll never see a line item you didn't agree to.
Age, refrigerant type, repair history and the cost of the fix all matter. Rule of thumb: if the repair costs more than a third of a new system and the unit is past ten years, replacement usually wins. We'll show you both numbers and let you decide.
Check that the filter isn't clogged, the supply vents are open, and the outdoor unit isn't packed with leaves or ice. If the outdoor coil is iced over, shut the system off and run the fan only — then call us. Running an iced system can wreck the compressor.
Yes — walk-ins, reach-ins, prep tables, display cases and ice machines, plus rooftop and split HVAC. Priority service agreements are available for sites where downtime costs money.
It depends on the failure, not just the brand of equipment. A capacitor or contactor swap is a fraction of what a compressor or heat exchanger replacement runs. We quote the diagnostic fee on the phone and the repair price on site, before any work starts, so you're deciding with real numbers instead of a ballpark from a search result.
Most central air conditioners run 12–15 years with regular maintenance; furnaces often reach 15–20. Coastal Delaware humidity and salt air can shorten that for units near the coast. Annual tune-ups are the single biggest factor in hitting the long end of that range instead of the short end.
It means if you call before early afternoon on most days, we can get a technician to you before the day is out — not "someone will call to schedule you." Same-day isn't guaranteed on every call (a rare parts-order situation can push a repair a day), but it's the outcome on the large majority of residential service requests.
Yes — JEM Comfort Care holds a Delaware Master HVAC Contractor license, the highest tier the state issues, and we carry full insurance. We'll provide a certificate of insurance on request for commercial and property management work.
Book online in about thirty seconds, or call and talk to a person. Either way you'll get a real arrival window — not a "sometime between 8 and 5."
