The purchase price unit cost is but one aspect of the overall cost consideration. Operating costs, and, if needed, service costs, are important factors. Proper air conditioning maintenance can help your unit last decades. On the flip-side, a neglected air conditioner loses roughly 5% of its efficiency each year that it operates without upkeep. So that green machine you bought to stay cool could start to function like the most inefficient thing on the market, if you fail to perform regular air conditioning maintenance. With a properly serviced air conditioner, problems will occur less frequently and you save money in the long run and get the most value for your investment.
Pull the shades and blinds on the sides of the house that get the most direct and intense sun. This will not only keep your home cooler, but will also protect your home from sun damaged furniture and sun damaged floors.
Filters and coils are both parts that require regular maintenance for your air conditioner to operate effectively and efficiently. Neglecting your unit leads to poor air conditioning performance and increased energy consumption. And regular maintenance is far less costly than repairs or a replacement.
By keeping your unit operating at peak performance, you will recover any money invested in upkeep by lower repair costs and savings on your electric bill.
