The selection of indoor units has one restriction - their total power should not exceed the capacity of the outdoor unit. In practice, however, it is very common to see a multi-split system with a total capacity of indoor units greater than the outdoor capacity by at least 20%. However, it is wrong to expect better performance when all indoor units are turned on at the same time, since the total capacity of the whole system is limited by the capacity of the outdoor unit. Simply put, the outdoor unit will distribute all its power to all operating indoor units in such a way that some of the rooms may not have a very comfortable temperature level. However, the calculation of the total power is not simple, since it takes into account not only the nominal power of the units, but also the cooling capacity, heating, dehumidification, humidification, venting, etc.

In 1820, English scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when the liquefied ammonia was allowed to evaporate. In 1842, Florida physician John Gorrie used compressor technology to create ice, which he used to cool air for his patients in his hospital in Apalachicola, Florida. He hoped to eventually use his ice-making machine to regulate the temperature of buildings. He even envisioned centralized air conditioning that could cool entire cities. Though his prototype leaked and performed irregularly, Gorrie was granted a patent in 1851 for his ice-making machine. Though his process improved the artificial production of ice, his hopes for its success vanished soon afterwards when his chief financial backer died and Gorrie did not get the money he needed to develop the machine. According to his biographer, Vivian M. Sherlock, he blamed the "Ice King", Frederic Tudor, for his failure, suspecting that Tudor had launched a smear campaign against his invention. Dr. Gorrie died impoverished in 1855, and the dream of commonplace air conditioning went away for 50 years.
Even if your air conditioning unit is still working, depending on the type of system in your home today, you could recoup your investment in a new system in as little as three years. However, that doesn't mean that your system needs to be replaced. Furnaces, air conditioners, and other heating and cooling systems have made tremendous gains in efficiency over the past five years, so if you have an older unit, it is worth taking a look at whether or not a repair is the best investment.
Got to say that I am very pleased with their work. The knowledge of the technician was on the spot. She was very professional at all times sharing her expertise and advice with me. Going further, I have hired some other pro's from this website to fix my AC and none them identified a faulty connection on the AC blower control board as my technician from Superior AC did. The price for the repair was fair, no overpricing at all. I am pretty sure that I will call them again and definitively recommend them. Thanks!! Aurelio
The standards do not require you to change your existing central air conditioning units, and replacement parts and services should still be available for your home’s systems. The “lifespan” of a central air conditioner is about 15 to 20 years. Manufacturers typically continue to support existing equipment by making replacement parts available and honoring maintenance contracts after the new standard goes into effect.

In modern buildings, the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally estimate the capacity and type of system needed and then design the system, selecting the appropriate refrigerant and various components needed. For larger buildings, building service designers, mechanical engineers, or building services engineers analyze, design, and specify the HVAC systems. Specialty mechanical contractors then fabricate and commission the systems. Building permits and code-compliance inspections of the installations are normally required for all sizes of building.
"Customer service was great, and the price was in-line with other places, and fast service. We had a whole replacement of the outside and inside. I would have liked to see a better install for the furnace and new thermostat - the new thermostat should have gone where the old one was, and even tho the new furnace was a tight fit, they didn't offer to come back and repair the case molding, or give me a discount on the damage done, and I believe they should have put a disconnect box on the outside of the home, to make it easier for any future repairs needed. Other than that, am very happy with the cooling and heating!"
I even asked if this is something they don't do, as in services on a Saturday night. I was told by the receptionist that they do and I would just be ok calling another company if they is not part of their services. They again assured me someone WILL call me in 10 mins. Well, unless their definition of 10 mins is never, then they got it wrong as I am still waiting to be called 5 days later.
Beyond changing the air filter on a regular basis, one of the best ways to ensure your home's HVAC system is operating at peak efficiency is to have a qualified professional HVAC contractor tune up the system on a biannual basis. Energy Star recommends scheduling your system tune-up around the beginning of daylight savings time in the fall and its end in the spring. It's an easy way to remember to have your system serviced before the peak heating and cooling seasons. A standard tune-up is likely to cost you between $70 and $100, but it's money well spent.
Here’s a simple test to try on your own: When it’s hotter than 80 degrees outside, turn on your AC unit, and set it to well below room temperature. Let it run for 15 minutes, then use a thermometer to check just outside the return duct (the area where air flows in to be cooled). Now take a temperature reading just outside the strongest, most easily accessible vent (where cool air should be flowing out). Subtract the second reading from the first. If the difference between these two is fewer than 14 degrees, your HVAC unit might need work.
If your air conditioner’s condenser coils, which are located in the outdoor unit, freeze up, your system will not run properly. Poor airflow through your cooling system can cause ice to form on the coils. Obstructions are typically the cause – such as dirty air filters or blocked return air ducts. Low refrigerant could also be the cause, requiring a refrigerant charge. A home AC repair technician can diagnose the issue behind your frozen coils, resolve it, and safely thaw your coils to restore cooling in your home.”
AC units and thermostats have built-in delay features when they’re shut down and then repowered. The delay can be as long as 10 minutes. And, if you’ve subscribed to an energy-saving device from your local power utility, the unit can take even longer to reset. If you’ve installed the parts shown and reinstalled the disconnect block, repowered the circuit breaker, turned on the switch at the furnace, moved the thermostat to AC mode and lowered the temperature below the indoor temperature, and the unit doesn’t fire up after 30 minutes, it’s time to call a pro.
