Lennox and Trane Reviews

A heat pump is an outdoor component of a heating and cooling system. It can cool your home similarly to an air conditioner, but it can also heat it. It draws heat from the cold outside air and transfers it to the indoors during colder days, and it pulls heat from indoor air to cool your home during warmer days.

Maintenance Needs

Lennox recommended that only authorized dealers should clean the coils, remove debris, and straighten the coil fins on a regular basis, as well as change or clean the air filters.

These things can be done by a technician during annual or seasonal maintenance to keep your heat pump in good working order. Expect to pay around $100 for an annual tune-up.

Trane recommends that you have a maintenance check routine, clear the area around the outdoor unit of any debris, regularly change your filters and a programmable thermostat should be installed.

Also, Trane advised at least once a year to contact your local dealer for a preventative maintenance check-up because there are things that only they can do or only they know.


Lennox has two types of heat pumps: Single-stage and multi-stage heat pumps. Both types are divided into three categories: Signature, Elite and Merit.

Trane heat pumps have three distinct product lines: XR, XL, and XV series.

Your heat pump will most likely not work properly if it is too small for your home. Because the heat pump will struggle to heat and cool your home, you may end up paying a higher utility bill.

On the other hand, If your heat pump is too large for your home, it will produce more energy than you require, wasting energy and lowering efficiency.

The general rule of thumb, every  500 sq. ft. of your house requires one ton of air conditioning. And one ton is equivalent to 12,000 BTU of the heat pump.

Which heat pump is the most reliable?

It can be challenging to choose the best heat pump brands. According to the research by U.S. News, Lennox placed at number four and Trane is fifth of the Best HVAC Companies of 2022.
