Yes! We offer 0% Financing or low monthly payment options for well-qualified clients. Our energy consultants will work with you to find the best boiler for your home and the perfect financing solution for your budget. 

Here are some key signs to look for:

  • Some rooms are hotter/cooler than others (ie. not heating evenly)
  • You are experiencing multiple or expensive repairs
  • The system is over 15 years old
  • You have noticed an increase in fuel costs
  • Your boiler’s flame is yellow instead of blue
  • Your system runs for a long time and doesn’t heat your home like it used to
  • Parts needed for your boiler are no longer available
  • The boiler is leaking
  • Your boiler takes a long time to heat up
  • The efficiency rating for your boiler is lower than an “A”

A New HVAC System can offer the following benefits: 

  • Energy Savings: Save on heating energy costs, which make up nearly 60% of your home’s energy bills. A new HVAC System can help save money in the long run and reduce your fuel costs.
  • Increased Efficiency: Older HVAC equipment loses efficiency at a rate of 2-6% per year, just like a car with high mileage. Along with becoming less efficient, old units will lose their capacity to cool. Newer boiler models with A-ratings have an efficiency rate of 90% or more.
  • Increased Comfort: A new HVAC system can dramatically improve your home’s comfort by getting rid of the uneven distribution of warm air.
  • Noise Reduction: Thanks to improvements in design, new boilers may be significantly quieter than old boilers making for much quieter operation. 

Unexpected repairs and part replacement are never fun. With all new equipment purchases, SMO Energy offers a warranty up to 10 years and optional Service Agreements to help you keep your warranty active and system running at peak performance.
