Yes, Dempsey Energy’s technicians are trained to work on both gas and oil furnace systems, plus electric heating systems. Many Green Harbor homes have older oil furnaces, while others have converted to gas or have newer gas installations. We can recognize the different types of furnaces and their specific maintenance requirements. Whether you’re dealing with ignition problems, circulation issues, or efficiency concerns, we have the knowledge to diagnose and repair your specific heating system properly.
This depends on several factors: the age of your system, the cost of repairs versus replacement, and how reliably it’s been performing. Generally, if your furnace is over 15–20 years old and needs major component replacements, a replacement might make more sense. However, many heating problems can be repaired cost-effectively, even on older systems. Our technicians will give you an honest assessment of your furnace’s condition and help you understand the pros and cons of repair versus replacement based on your specific situation and budget.
First, check your thermostat settings and make sure it’s set to heat mode at the right temperature. Check your circuit breaker to make sure power is getting to the furnace. For gas furnaces, make sure the gas supply valve is open. If these basic checks don’t solve the problem, call for professional service rather than trying to troubleshoot further. Furnace systems involve gas, electricity, and elaborate mechanical components that require proper training to service safely. Document any unusual sounds, smells, or behaviors you noticed before the system stopped working—this information helps us diagnose the problem more quickly.
Annual furnace maintenance is recommended for most heating systems, ideally scheduled before the heating season begins in fall. This preventive service includes cleaning, inspecting all components, testing safety systems, and replacing worn parts before they cause bigger problems. Regular maintenance helps your furnace run more efficiently, reduces the likelihood of emergency breakdowns, and extends the system’s lifespan. For older furnaces or systems that work harder due to poor insulation or other factors, more frequent service might be beneficial. The Dempsey Comfort Club offers structured maintenance programs that make it easy to stay on top of furnace care.
We focus on honest diagnostics and transparent communication throughout the repair process. Our technicians explain what’s wrong, what the repair options are, and give you the information you need to make positive decisions about your heating system. We use modern service tracking systems to verify consistent follow-up and maintain detailed records of your equipment’s service history. With over 12,000 customers in our database, we have the experience and systems in place to provide reliable service. Our goal is building long-term relationships with Green Harbor homeowners, not just making quick sales.
