Before you make your decision based solely on price, consider this:  What will that “savings” cost you down the road?  Some companies don’t care about what is best for you, they care about getting the job.  If you want a low price, many companies will figure out a way to hit that mark.  But at what cost?  You need to trust that your Installation Professional is guiding you in the right direction, with the correct equipment for your home and for your needs.  You need to feel a sense of trust in that person.

When we quote a job, there is a process.  We take the time to understand you, your needs, and your budget.  We do not cut corners, because we understand taking shortcuts will cost YOU in the end.

  • We will not provide a quote for an Installation over the phone. 
  • We will come to your home and meet with you. This provides us with an opportunity to understand exactly what your heating needs as well as your budgetary concerns are.
  •  We will take the time to measure your home and perform a heat loss analysis to ensure that we install the correct size equipment for your Heated space.  
  • Systems that are too large or too small both create issues that lead to poor-running systems. Over sized equipment will consume far more energy than a properly sized system.
Keeping your Furnace or Boiler Clean


Not only does a cleaner furnace alleviate allergy or asthma symptoms, it also ensures that your heating system will last longer. We recommend an Annual Tune Up to help prevent furnace breakdowns and carbon monoxide leaks. Even though gas-fired systems burn cleaner than oil, high efficiency gas furnaces & boilers still require cleaning & maintenance due to the condensing action within the heat exchanger. The annual tune up service typically includes, but are not limited to the following:

- Vacuum Out Combustion Chamber                                                       
- Clean Heat Exchanger Surfaces                                                            
- Service Burner Assembly                                                                      
- Flue Pipe and Fresh Air Intake Cleaning
- Indoor fan assembly cleaning
- Clean condensate drain, trap and pump                                              
- Replace Fuel Oil Nozzle, Fuel Oil Filter & Pump Strainer
