Professional AC Installation for Ontario Homes and Light Commercial Spaces

We use a cooling load calculation that accounts for insulation, windows, orientation, air leakage and ductwork. Square footage alone is not a reliable guide.

Sometimes. The line set has to be clean, correctly sized and undamaged, and the coil has to be compatible with the new outdoor unit. If either one is questionable, we recommend replacing it.

Yes, for light commercial spaces such as small offices and retail units, depending on the scope. We review the load, the ductwork and the electrical supply first.

We note leaks, restrictions and return air problems during the site review and explain how each could affect comfort. You can have them fixed with the install or later, and nothing is added without your approval.

Kelvin Mechanical works with licensed and qualified professionals and trade partners, depending on the project scope. Electrical and refrigerant work are handled by the appropriate qualified people. Permits and ESA notification are arranged where required.

A central air conditioner is often expected to last somewhere in the range of 12 to 15 years, though installation quality, maintenance, run time and dirt all play a part. Because Ontario has a short, intense cooling season, the unit sits idle for much of the year. Age matters, but repair history and refrigerant type matter too.

It depends on the municipality and the work. Some cities require an HVAC or building permit for a new air conditioner, and electrical work may need its own permit. Rules differ by municipality and change, so we confirm what applies before work starts, and permits and inspections are arranged where required.

Often yes, through a ductless system or, in some homes, new ductwork. Bungalows, two-storey homes and houses with hot water radiators each have different options, and the right one depends on access, ceiling space and budget. A site review shows what is practical. See ductless mini split installation for homes without ducts.

A heat pump cools like an air conditioner and also heats. If you are replacing both your furnace and air conditioner, it may suit. If your furnace is fine and you only need cooling, central air may be simpler. Rebate programs may apply to heat pumps depending on the rules at the time. See heat pump installation.

The unit needs clear airflow and service access, and it should avoid spots under windows, decks or roofs that shed snow. Many municipalities have bylaws on placement, setbacks from property lines and noise. Rules differ by municipality, so we check before the unit is set.

Not always. If the furnace is in good shape and its blower and airflow suit the new coil, the two can be matched. If the furnace is near the end of its life, replacing both avoids a second project later. We explain the options after the site review. See furnace installation.

New equipment is moving from R-410A to lower-global-warming refrigerants such as R-32 and R-454B, and the type depends on the equipment you choose. Ask which one is used, what that means for future servicing and how parts are supplied. R-22 has been phased out, so refrigerant supply for older R-22 systems is limited.

Spring, before the first heat wave, gives you the most flexibility. Equipment availability and scheduling tighten when hot weather arrives. A fall or winter install is also possible, and it can be useful if your old unit failed late in the season. Start with Build My Quote.

SEER2 is a seasonal efficiency rating for air conditioners and heat pumps. A higher number means less electricity used for the same cooling under test conditions. It is one factor alongside correct sizing, installation quality and ductwork. Compare models of similar capacity, and ask which rating applies to the equipment being quoted.
