Furnace life expectancy

Furnaces last an average of 15 years with proper maintenance,but boilers can last even up to 30 years with annual inspections and flushing .

One of the greatest investments we make is our home.  We want our surroundings to provide us with a welcoming environment that simultaneously appeals to our sense of style and keeps us comfortable no matter the season.

So we invest in climate control systems to keep us warm in winter and cool in summer .  It is up to us to ensure our systems are kept in good working order .

Most of us are aware of the importance of annual maintenance for furnaces/boilers and air conditioning. A checkup to ensure it is ready for the upcoming season.  It is a good idea to schedule these annual inspections in advance to ensure continued comfort as the seasons change .

Furnaces last an average of 15 years with proper maintenance and above all they will start costing you money once they pass 15 years .  Sometimes replacing the furnace will be less expensive in the long run.

Boilers  can last up to 30 years if they are maintained properly and installed according to manufacture specifications.

It is important to read the installation guide to any appliance.  The bulk of our work is service and maintenance.  We replace when needed .  We often find and correct mistakes technicians have made during installation.  We can not stress how important it is to read and follow the manufacturer’s installation guide to ensure a longer life for the appliance and also comply with warranty requirements.

Annual maintenance and upkeep on energy efficient appliances is a small price to pay to save replacement costs!

Protect your investment with routine inspections.

Correctly Charging AC Units

Many people may wonder why HVAC companies will not maintain or recharge your AC unit on a cold day. It is simply not an effective way to test freon levels.

Cold Temperature Charges

You can work on these units in the cold and some technicians use “insulated blankets” to wrap the outside condensing units with to create a head pressure rise. This simulates a hot day, they can then add or remove refrigerant based on that reading. The problem with this technique is the head pressure rise is more of an estimate. With this estimate of head pressure you are not getting an accurate reading therefore it would be easy to overcharge or undercharge the unit.

This results in you as the customer being inconvenienced by your unit still having issues and possibly having to pay for the same service to be done on a hot day. When charging your unit on a hot day you will get a accurate reading therefore resulting in a cheaper repair and peace of mind that your unit will be operating correctly. This is the preferred method to work on AC units because we know we are getting a correct reading and will not have to worry about an unhappy customer or wasted time. The correct temperature for recharges is 70-75° F.
