The Hazards of Do It Yourself Furnace Installations!


OK, your furnace is 25 years old, it’s inefficient and undersized. You get on the telephone and call around and figure out that a brand-new furnace does not actually cost that much. It’s the installation labour that runs up the cost! So, you think you’ll just change out the heating system yourself and save a bundle? Sounds rather good on the surface? Why Not? Well, here’s reasons why not.

Furnace and central air conditioning specialists get a great deal of AC repairĀ  training. They understand how to get the job done correctly and they recognize the incorrect ways to perform the task, they own the instruments for correct installment and testing and they’ve been educated in how to get the job done safely and effectively. This is certainly a circumstance where what you don’t know can harm you.

Air conditioning systems need to be installed by professional technicians. The coolant that is pumped through the system is captured and saved. Releasing this coolant in to the atmosphere produce environmental degradation. You have to be qualified and licensed to handle the coolant involved in air conditioning replacement, repair or installation.

A fundamental part of the task is determining which new unit should be installed. A knowledgeable HVAC contractor can advise you on which unit is best for your home and your circumstance. Brand, model, sizing and efficiency are all important factors in selecting an HVAC unit.

The routine when replacing a central heater is, roughly, as follows. The gas lines, plumbing, refrigerant lines and electrical are disconnected, capped and protected, as needed. The ductwork is detached from the old unit. The old central heater is taken out. Getting a heating system out of a furnace closet is often more difficult than expected. The installer will haul the old system off, and probably recycle it. The furnace location is then cleaned and readied to receive the new system.

Prior to installment of the new system, the ductwork will most likely have to be modified to fit. Once the new device is in place, and the ductwork, the plumbing, electrical wiring and gas and refrigerant lines are all correctly connected, the gas lines and the HVAC system is tested. The technician will also run the furnace and check for carbon monoxide gas, a dangerous combustion byproduct that can pass into the heated air if the unit is deficient or the installation is done incorrectly. The thermostat might also have to be replaced, programmed and checked.

So, altogether, the replacement of a heating system is a challenging job. It needs specialized tools, components, training and expertise. It’s a project best left to to the professionals who know what they are undertaking. Give your qualified HVAC compny a phone call. He will perform a good job and save you money and trouble in the long run. He are so proficient, he will make it appear simple. You might think, I could have done that! But, you made the right choice leaving the job to a professional.
