When your existing system not longer does the job it once did, or is older than 10 years it's time to seriously think about a new High Efficiency Air Conditioner system installed prior to the end of the year!
Right after that, you need to make sure that you do it right. Here are some steps to help you pick a system that very best suits your needs and budget. First off List the things about your existing system you'd like to change or make better, you can use the following questions to assist determine this and discuss them with your Air Conditioning Professional:
1. Could be the air flow to all rooms acceptable ( do you might have hot and cold spots within your property) This really is typically a duct system problem ( too tiny of a duct feeding the room, or that section of residence) This really is simple to fix by growing duct size or far better however "home run" a correct size duct from the air handler/furnace towards the existing room grille in question. Please note: Increasing the size with the new ac system typically exaggerates the hot & cold differences with increased air flow everywhere. (the longer a comfort system runs the more even the temperatures.
2. Is the old one creating noises? New systems range generally from 68 db (near silent to 80 db (sounds like a lawnmower) be very aware of db ratings if system is near a bedroom or TV room window.
3. Economy - the most often used gauge of air conditioner comparison is SEER (Seasonal Energy Efficiency Ratio) this really is much like gas mileage with a car. Less electricity will be used if the number are higher. The is a comparison of units at 82 degrees. EER is a comparison of equipment at 95 degrees which is more accurate for the times you'd be running the AC system. The more you may spend now on an efficient AC system the less electric you'll use and your saving will be increased for the next 10 - 15 years of ownership. Take note there is point of diminished return in my opinion, whereas payback on electric exceeds 5-8 years.
4. The air quality indoors: Anyone inside your house has allergies? There's lots of upgrades in filter media or electronic devices to take out dust, mold, bacteria, viruses and yes even volatile organic compounds (smells such as off gassing of paints or carpets.)
