Will a high-efficiency air conditioning system be paid for?


Home Heating HVAC (Heating Ventilating Air Conditioning) systems in most climates will be a major user of energy. In warm climates, it can account for 60% or more of your total electricity bill. If your system is ten years old or older, it is a preferred candidate for an upgrade. The air conditioning systems are evaluated by SEER (Seasonal Energy Efficiency Ratio). This is a kind of MPG qualification of cars. The higher the number, the more efficient energy and the less energy it will consume for the amount of cooling compared to a lower SEER system. A system of 10 years or more was probably rated at 10 SEER or less when it was new. As they get older, they can lose efficiency due to loss of compression and heat transfer restrictions such as a dirty or damaged coil. If you have an older unit that needs repairs, you might be tempted to spend the few hundred or a few thousand dollars it will take to turn it on rather than the thousands that would have to be replaced by A high-efficiency system. Repairs can often be the best alternative with a tight budget or in case you do not plan to stay in the house long enough to get a ROI (return on investment) from the new system.

But in the long run, it is more expensive to repair an older unit than to replace. If you have an average house of 2,000 square feet with a 4 ton air conditioning unit, it could cost about $ 5,000 to replace more or less a thousand euros depending on the quality of the Equipment and everything that is involved in the installation. If this hypothetical system required repairs in the typical range of $ 600 to $ 1,000, it might appear that you are saving about $ 4,000 by repairing instead of replacing. But you need to consider future operating costs and repair and maintenance to get a real cost comparison. If your system begins to need repairs in this price range, chances are good from year to year, it will take even more repairs as it gets older. If you add refrigerant due to a leak and do not repair the leak, you are guaranteed at least one, but probably several phone calls a year to cool it. Finding and repairing small pinhole leaks in the reel can cost a lot too. Repairing leaks from the coil can be very difficult. When the coil begins to leak, it is likely that there are many small pinhole leaks in the tube where the wing contacts the tube. This is due to the electrolysis caused by the contact of two dissimilar metals and the presence of volatile organic compounds (VOCs) on the coil that contribute to the formation of these pinholes. Repair is a delicate process and can result in results below the desired results. Repairing a leak can simply open another nearby. Even if you succeed, the efficiency of the system can never be returned, even if its initial level of 10 SEER is much less important. Load a leakage system to "go through" also contributes to the cost of operating this system. You have the service costs plus the increased operating cost because the system loses refrigeration liquid and becomes less and less efficient.

Let's look at the $ 5,000 system verses that keep your old system over a period of only five years. At the front, we already know that you will have a cost of about $ 1,000 for the system to operate even at a low efficiency level. So, now we go up to $ 4,000. Now, tell yourself that you have a very low average maintenance and service cost of $ 350 for years 2 to 5. Now the new system costs you only $ 2,600. Most systems will have a 10-year parts warranty, even if something has failed at least the parts would be covered. The workforce for repairs on the new system will be at least 1 year and up to 10 years can be added for about $ 500.00 on most systems.

We have not even talked about saving energy costs. According to a software comparison of operating costs using 0.11 cents per kilowatt hour and a modest increase of rates of 3% per year, you save $ 2,922 on the cost of air conditioning by passing To an Energy Star system rated 14 SEER from the 10 SEER system. And this assumes that your 10 SEER system is still running at 10 SEER. I can say that this will not be the case. Savings will vary.

According to the same cost comparison software, government studies also showed an increase in residential value of about $ 7,800 by performing this upgrade. When we extend the time to the expected average life of the system to 20 years, your savings exceed $ 10,000 in operating costs.

So wait until this old system fails to replace it can cost you much more in the cost of energy and comfort and then replace it now.
