We recommend annual professional maintenance, ideally in the Fall before winter starts. Regular maintenance ensures optimal performance, prevents unexpected breakdowns, and maintains your warranty.
FAQ
Do You Offer Financing Options?
Yes, we offer flexible financing options with approved credit, including plans with 0% interest for qualified customers. We believe cost shouldn't prevent you from having reliable, efficient systems in your home. Our team can help you find financing solutions that fit your budget.
When Should I Replace My Heating System?
Most heating systems last 15-20 years with proper maintenance. Signs it's time for replacement include frequent repairs, rising energy bills, uneven heating, and strange noises. If your system is over 15 years old and facing a major repair, replacement often makes more financial sense.
How Can I Improve My Heating System’s Efficiency?
Regular maintenance is key! Schedule annual tune-ups, change filters regularly, seal air leaks, add insulation, and consider a programmable thermostat. These simple steps can reduce heating costs by 20-30% while extending equipment life.

"Alex arrived on time and was very polite. We learned more from him than any other technician who came to check our furnace. Our furnace is only 2 1/2 years old but no one before told us to change batteries in the thermostat. Alex answered all my questions about the furnace humidifier.
Alex is a very knowledgeable young man."
