Q. How do I know whether to repair or buy new?A.
In making this decision, evaluate life expectancy of your unit, operating cost, and the overall situation.
If you are frustrated with an equipment breakdown, it can be tempting to find the cheapest fix to get on with your life in comfort. That cheap fix may be the least expensive now but may not give you the most value or be cost effective in the future. Paying for repairs to an old or inefficient system often prolongs the inevitable. An older system that breaks down once is likely to break down and be down often. This means more emergency service calls or worse, the risk of damage to your home or to other components of your system. Operating Cost-
Cost factors must also be carefully considered. Restoring your old system will only bring it back to its current level of energy efficiency. After you have recovered from the repair bills and system breakdowns, you still will not save on your energy bills. Even six year old heat pumps and air conditioners are considered inefficient standards. So are most furnaces built before 1980. So you could save up to 60% on your energy bills with new high efficiency equipment. Installing a new heating and cooling system can actually pay for itself in energy savings within a relatively short time. Overall Situation-
When one component of your system breaks down unexpectedly, it is easier to focus on repairing or replacing that component. But each part of your system works with the others to boost efficiency and reliability so it helps to keep the big picture in mind. Replacing your old furnace with a new higher efficiency model but leaving your old mechanical thermostat in place for example, will not allow you to enjoy all the efficiency advantages the furnace has to offer. Likewise, if you install a new furnace but do not accompany it with a humidifier, the air may seem cooler, forcing you to operate your new system at a higher temperature to be comfortable. You can often save on installation costs if you have several components of your system replaced at the same time.
