New air conditioners for old houses

Living in the same house in Toronto for many years is in itself a badge of honor, for you get to experience so many moments with your loved ones in the same place you grew up. The variety of seasons in the GTA, however, may test your house’s endurance, including the effectiveness of your HVAC systems. With summer around the bend, your A/C system, in particular, may be at risk of breaking down. You must have a trusted air conditioning service provider upgrade the system.

To upgrade an A/C unit in an older home, a contractor may choose either a mini-split or a high-velocity A/C. Mini-split systems are composed of a main compressor and fan unit that are positioned away from sunlight and linked to a number of individual cooling units inside the house.

The high-velocity system, on the other hand, allows the transfer of cool air via insulated piping to some sections of the house where they will be distributed through registers.

A reputable air conditioning specialist should be allowed to analyze the entire house and calculate the value of the cooling load the house needs, then designate the compressor system based on the house voltage. The analysis will include the number of windows, the floor area, and the heat distribution around the house.

An old house that has stood for decades may have its hidden cracks and holes, but a modernized air-conditioning system installed by HVAC experts will bring a higher level of comfort to its occupants.

Reasons Why Air Conditioners Freeze Solid

You turn on your air conditioner in the middle of a hot day, but notice that it isn’t cooling your home properly. Thermostat’s pointed to “cool” dial, the unit’s plugged in, but the air still isn’t getting any cooler. Chances are, the A/C’s own guts have frozen inside – but how does this happen?

One of the most common causes of a frozen A/C is a dirty air filter. Over time, dirt and grime accumulate on the filters and restrict airflow, thus keeping the cold air circulating inside. In turn, the unit’s guts freeze because the cold air can’t escape. Cleaning or replacing the filter can fix this.

Dirt and grime are not the only one that clog air filters. Improperly positioned furniture or any other items can block the A/C’s return air vent, or the opening where the air passes across the evaporator coil. Obstructive items can block overall air flow, so be sure to clear up the space near the air conditioner.

A malfunctioning thermostat is another culprit for internal freeze. If the thermostat dial isn’t working properly, the A/C will run continuously without turning off and on, even when the temperature’s set point is reached. This could definitely result in ice-covered coils.

Other reasons for the deep freeze may be an ailing evaporator fan or refrigerant leak. These fixes require a much more trained hand, so unless you’re trained to do air conditioning repairs, better call a service technician immediately.

Tips on Choosing an Air Conditioning Service

There are simple fact checks you should do before selecting a reputable HVAC contractor. You want to make sure that the prospective contractor is trustworthy and worth being paid every penny. Here are some questions you could ask your prospective contractors before choosing one.

Does the contractor have proper documentation? Check if the prospective contractor has all the necessary documents, including licenses, government certifications, and insurance policies (if any), before going any further. You wouldn’t want to invest in an illegally operated HVAC company, would you?
