Keeping your home warm in the winter and cool in the summer requires HVAC equipment that is properly installed, well-maintained, and in good working order. COD Delivery doesn’t just deliver home heating oil: we also install and service heating and cooling systems to ensure your home is comfortable year-round.

Heating
Installation
Whether your home is heated by oil, gas, or electricity, a new system may run more efficiently and save more fuel and money than you thought possible.
It may be time for a new furnace/boiler if:
- Your furnace or boiler is more than 10-15 years old;
- The system requires frequent repairs;
- Your home is heating unevenly;
- Your power bills or oil usage have increased significantly with no other obvious cause;
- The furnace, boiler, or blower is loud or is making strange noises;
- Air quality is poor, especially if you see excessive dust in your home or if you experience unpleasant smells when the heat is running.

MAINTENANCE
If you have a furnace, a boiler, or another type of heating system, proper maintenance can keep your equipment running efficiently all winter long and lessen the likelihood of expensive surprise repairs.
We suggest an annual tuneup by one of our licensed technicians where we will check all aspects of your heating system, including electrical connections, voltage and current, fan belt, oil or gas connections (if applicable), and condensate drain. We will also test the ignition, the exhaust system, system controls, and carbon monoxide levels (if applicable). We will make minor adjustments when necessary and inform you of any problems that will need to be addressed to keep your system operating safely and effectively.

Our team of expert technicians can repair all types of heating systems. Whether it’s a small fix or a major repair, give us a call or schedule service online
Cooling
Installation
If you’re looking to install your home’s first air conditioning system or you’re replacing an existing system, our experienced techs can help you keep your cool when the temperature rises.
Signs you may need to replace your air conditioner:
- Your air conditioner is more than 10-15 years old;
- You need to make frequent service calls;
- The system is blowing warm air or very little air at all;
- The air conditioner runs constantly;
- Your energy bills are higher than usual;
- Your home is more humid than it should be;
- The system is making loud or unusual noises.

MAINTENANCE
Your air conditioner is an investment in your warm weather comfort. Proper maintenance prevents unexpected problems when you least expect them, and extends the life of your system.
It’s important to change the filters regularly and to keep your outdoor unit free of dirt, trash, and yard debris. It’s just as important to schedule a seasonal tune-up with an HVAC pro so we can check your system for any small problems that could turn into big ones.
During a routine seasonal tuneup, we check your compressor, condenser coils, evaporator, fan, and drains. We may also run additional electrical diagnostics and check your thermostat to ensure it’s functioning properly. At this time we can make minor repairs or adjustments to keep your system operating as efficiently as possible.
