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

Furnace and air conditioning technicians have a great deal of AC repairĀ  training. They understand the best ways to get the job done correctly and they know the incorrect ways to do the job, they have the equipment for correct installation and testing and they’ve been trained in the best ways to do the job safely and effectively. This is definitely a situation in which what you don’t know can harm you.

Central air conditioning systems have to be installed by professional specialists. The coolant that is pumped through the system is captured and saved. Releasing this coolant into the atmosphere results in environmental degradation. You have to be qualified and licensed to handle the coolant involved in air conditioning replacement, maintenance or installation.

A fundamental part of the job is determining which new unit should be installed. A knowledgeable HVAC professional can advise you on what system is most effective for your home and your circumstance. Brand, model, sizing and efficiency are all critical factors in selecting an HVAC system.

The routine for replacing a furnace is, approximately, as follows. The gas lines, plumbing, refrigerant lines and electrical are disconnected, capped and secured, as required. The ductwork is detached from the existing unit. The old central heater is taken out. Removing a furnace from a heater closet is oftentimes more challenging than expected. The installer will carry the old system off, and most likely recycle it. The heater area is then cleaned and prepared to receive the new unit.

Prior to installment of the new system, the ductwork will most likely need to be modified to fit. When the new unit is in place, and the ductwork, the plumbing, wiring and gas and refrigerant lines are all correctly attached, the gas lines and the HVAC system is tested. The technician will also run the system and inspect for carbon monoxide, a hazardous combustion by-product that can leak in to the heated air if the unit is deficient or the setup is done incorrectly. The thermostat may also need to be upgraded, programmed and checked.

So, all in all, the replacement of a heating system is a complicated job. It needs specialised tools, parts, education and expertise. It’s a project best left to to the pros who understand what they are undertaking. Give your qualified HVAC compny a phone call. He will do a good job and save you money and grief in the long run. He are so good, he will make things look simple. You may think, I could have done that! However, you made the right choice giving the job to a pro.
