What Our Customers Say
quality
“Technicians performed the regular maintenance on the a/c system and they were very thorough in the inspection and in running the heating and cooling systems. Great job and provided feedback on the condition of the system.”
professionalism
“Our home HVAC system was installed by DelAir 7 years ago and recently had a few issues come up and DelAir has been prompt and effective in getting them resolved under the 10 year parts and labor warranty. Thank you again for a continued smooth ownership experience.”
speed
“Great experience today with William from Del-Air. He came out late in the day to help make a maintenance appointment happen on my heat pump. Fast, professional, and more than willing to explain the process as he went. Thanks to him and the team!”
If your heater is not working in your house, check a few simple items first and schedule professional service if it still won’t run. The most common culprits are thermostat settings or a tripped breaker, followed by a clogged air filter or a full condensate drain that trips a safety switch. A technician sees this often: a stuck float switch can stop heat with no obvious warning on the thermostat. We help homeowners across the Winter Park area with same-day and 24/7 emergency support when basic checks don’t restore heat.
Try these quick, safe checks before you call:
- Set thermostat to Heat and a few degrees above room temperature; replace thermostat batteries.
- Verify the furnace/air handler switch is On and reset a tripped breaker once after waiting 5 minutes.
- Replace a dirty air filter and make sure supply and return vents are open.
- If accessible, power off and look for a full condensate pan or float switch trip; don’t bypass safety devices.
If you smell gas, hear electrical arcing, or see scorch marks, keep power off and call a licensed technician immediately.

Heating system installation pricing is confirmed after an in‑home evaluation because the right system and scope vary by home. The biggest driver is the type of equipment you choose (heat pump, furnace, or ductless), followed by the size needed to heat the space efficiently. Our team regularly installs and replaces systems for homes across the Cassadaga area, and we provide clear options before any work begins. Free estimates and financing options are available.
You’ll see cost change based on:
- Equipment type, capacity, and efficiency level
- Ductwork condition or modifications (repair, sealing, or new runs)
- Installation access and labor complexity (attic, crawl, or tight spaces)
- Add‑ons like smart thermostats or indoor air quality upgrades
If your existing system is failing often, a replacement can be more economical than repeated repairs, while newer systems may only need targeted fixes. Schedule an on‑site assessment to get a firm price and the correct system size for your home.
