Local Knowledge
Cottage country is a different heating problem.
Gravenhurst runs cold and long, and much of the housing started seasonal. Cottages converted to year-round living carry minimal ductwork, crawl spaces, and equipment sized for weekend use rather than February. Fixing that is retrofit planning: load, routing, returns, and venting before any equipment is named.
Many Muskoka properties are also not on a natural gas line, so heating runs on propane, oil, or electric. That changes the math. Heat pump options, correct sizing, and backup heat are worth reviewing properly before replacing like for like.
Larger lakefront homes around Muskoka Bay and Sparrow Lake add long duct runs, multiple levels, and space that has to hold temperature while nobody is there. We also serve Kilworthy, Severn Bridge, and Washago.

Answers before you book.

Yes. Navraj Air Systems serves Gravenhurst and the surrounding Muskoka area. We handle furnace installation and repair, air conditioning, heat pumps, ductwork, tankless water heaters, smart thermostats, gas lines, commercial HVAC, and new construction HVAC.

We book scheduled visits for installations, replacements, and service work in Gravenhurst. Call 647-669-5009 or send your details through the quote form, and we will confirm timing and the next step for your address.
How much does a new furnace or air conditioner cost in Gravenhurst?
Cost depends on the size of the property, the efficiency level you choose, the condition of the existing ductwork, and access to the mechanical room. We quote after we understand the property, and the quote is free with no obligation.
Should I repair or replace my furnace or air conditioner?
Most systems last about 10 to 15 years. If your equipment is in that range, the repair is a major one, or your bills keep climbing, replacement is usually the better long-term value. We show you both paths and what each one actually solves.
Can you fix uneven temperatures and weak airflow in a Gravenhurst home?
Yes. Uneven temperatures usually trace back to equipment sizing, duct layout, return air, balancing, or controls. We check those first so you are not paying for larger equipment that does not fix the real cause.
Do you install heat pumps in Gravenhurst?
Yes. A heat pump can handle both heating and cooling, and it can be paired with a furnace or backup heat for the coldest stretches. For properties without a natural gas connection, we will walk you through the options before you commit.
Do you work with builders and commercial properties in Gravenhurst?
Yes. We handle new construction HVAC for custom homes and multi-unit projects, and commercial HVAC for offices, retail, and small business spaces in Gravenhurst.
Are your HVAC technicians certified, licensed, and insured?
Yes. Navraj Air Systems works with certified, licensed, and insured technicians for residential and commercial HVAC work.
