Heating and cooling system replacement
A replacement should solve the comfort problem, fit the property and make sense for the budget—not just match the old model number.
How we can help
Choose a system that fits the home.
Ottaway Mechanical replaces furnaces, air conditioners, heat pumps, air handlers and complete HVAC systems. We start with the property, existing ductwork, fuel source and comfort complaints before recommending equipment.
The old model number is useful, but it is not the entire sizing process. We consider the heating and cooling load, airflow, electrical requirements and the way the home is actually used. You receive clear equipment and installation options before making a decision.
What we look at
The whole system matters.
- Existing equipment capacity and condition
- Home size, insulation and comfort complaints
- Duct and return-air limitations
- Electrical, gas, drain and venting requirements
- Startup readings and customer walkthrough
Straight answers
Replacement should fix more than the breakdown
A new system should address comfort, airflow and operating concerns that the old equipment left behind. We explain good, better and best-fit options without pretending the highest-priced option is automatically the right one.

System replacement FAQs
Do you offer heat-pump options?
Yes. We install standard and cold-climate heat pumps, including ducted systems and ductless mini-splits when they fit the property.
Will you check the ductwork before replacing equipment?
Yes. Equipment cannot perform correctly without suitable airflow. We look at the visible supply and return system and explain any limitations that should be corrected.
Service and diagnostic visits are paid. Estimates for full equipment replacement or new installation are free.
