Comprehensive Heating & Cooling Services in Sussex
Fast repairs, honest guidance, and quality work that holds up for the long haul.
When your system starts acting up, you need more than a quick fix. You need clear answers, fair pricing, and a team that knows how to solve the problem without wasting your time or selling you work you don’t need.
We provide heating and cooling services in Sussex for homeowners and small businesses who want reliable comfort and real peace of mind.
Cooling Services
When your air conditioner can’t keep up, airflow drops, or the system starts freezing, leaking, or short cycling, we find the cause and fix it the right way. We offer:
- Air conditioning repair for poor cooling, frozen coils, refrigerant issues, electrical faults, drainage problems, and worn parts
- Air conditioning installation and replacement for older, inefficient, or failure-prone systems
- Air conditioning maintenance to improve performance and reduce breakdowns
- Ductless mini-split service and installation for older homes, additions, finished spaces, and areas without ductwork
- Heat pump service, repair, and installation for efficient year-round heating and cooling
When replacement is the smarter long-term move, we’ll show you why. We help you compare system size, efficiency, comfort, and operating costs, and our instant online quote tool lets you quickly start exploring new system pricing.
Heating Services
Reliable heat matters in Sussex, especially when an older furnace, boiler, or heat pump starts failing in cold weather. We carefully diagnose the issue, explain your options clearly, and help you make the right decision for your home. We offer:
- Heating repair for furnaces, boilers, heat pumps, and other heating systems
- Heating installation and replacement, including high-efficiency equipment
- Heating maintenance to improve reliability, safety, and system life
- Oil-to-gas conversion planning and installation
- Oil tank removal and related heating upgrades when needed
A lot of homeowners call us when they’re tired of putting money into a system they no longer trust. We help you weigh repair versus replacement based on age, condition, repair cost, efficiency, and long-term value. If replacement makes more sense, we can also help with financing, rebates, and incentive options.
Indoor Air Quality and Home Comfort
A home can feel off even when the temperature looks right. Dry air, excess humidity, dust, and poor filtration all affect comfort. We install and service:
- Filter upgrades and replacement options
- Whole-home comfort improvements tied to your heating and cooling system
If you want a simpler way to stay on top of air filtration, we also offer online filter purchasing.

“I wish I had found this company sooner”
We had an issue with our furnace that Willco was able to diagnose that another HVAC company had missed. Willco was very professional and explained everything clearly. Communication with office staff was friendly and courteous. I wish I had found this company sooner. —K. Wagenbach
Bill Cowan built Willco on workmanship first, and that standard still drives our work today. We’re not trying to be the cheapest option. We’re here to be the team you feel good calling again because the work was done right the first time.
The Willco Way
A heating or cooling service call should bring relief, not more stress. Too many homeowners get vague answers, shifting prices, or a replacement pitch before anyone has fully diagnosed the problem. We handle it differently.
When you call Willco, you can expect:
- Real people who answer the phone and help you schedule service
- Careful diagnosis before we recommend a repair or replacement
- Clear explanations and flat-rate, upfront pricing before work begins
- Respect for your home, your time, and your budget
- Support after the job if questions come up later
With flat-rate pricing, you approve the repair cost before we start. You don’t have to watch the clock or worry about a longer visit leading to a bigger bill. You get clear pricing, honest guidance, and work done right.
