The performance of vapor compression refrigeration cycles is limited by thermodynamics. These air conditioning and heat pump devices move heat rather than convert it from one form to another, so thermal efficiencies do not appropriately describe the performance of these devices. The Coefficient-of-Performance (COP) measures performance, but this dimensionless measure has not been adopted. Instead, the Energy Efficiency Ratio (EER) has traditionally been used to characterize the performance of many HVAC systems. EER is the Energy Efficiency Ratio based on a 35 °C (95 °F) outdoor temperature. To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER, the Seasonal Energy Efficiency Ratio (SEER), or in Europe the ESEER, is used. SEER ratings are based on seasonal temperature averages instead of a constant 35 °C (95 °F) outdoor temperature. The current industry minimum SEER rating is 14 SEER.

If your air ducts have been damaged, you’ll need to replace them. The national average air duct replacement cost is $150-$280, which may not include materials. Factors such as duct material, labor, location of ducts and linear feet of ductwork will all affect your final costs. Labor costs will vary based on how accessible the ducts are and what material your ducts are made of. The least expensive duct material is a flexible, non-metallic ducting that costs approximately $1-$2 per linear foot. Flexible aluminum is generally more expensive and stronger than non-metallic ducting. Stainless steel ducting is the strongest, the least flexible (meaning installing it typically has higher labor rates), and usually the most expensive. An average price for air duct replacement could range between $35 and $55 per linear foot, including basic materials and labor. A typical single-family home has 6-10 duct runs; replacing or installing one duct run could average $150-$250 for labor.
Also, have an energy-efficiency professional come to your home and perform an energy assessment. This assessment could be either conducting a walk-through of your home with a clipboard or performing a thorough audit, pressurizing your home with a blower-door test to detect energy leaks. You may qualify for state discounts or rebates to have insulation installed in your home. Some utility companies also subsidize the cost of these energy efficiency assessments.
In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York. After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.
BIG THANK YOU for being honest, and advising us that for some reason the fuse/switch was in the reverse position so the AC unit would not properly turn on. The unit turned back on immediately, and began cooling the house. And then providing advice that the AC/Heating system needed some TLC, and giving us options to save money by purchasing a maintenance plan that included the filters plus cleaning services since we were already being charged for the service today.

"Friendly, professional, responded quickly to my problem. I have called many air conditioning companies about my problem including the maker of the unit and had come to the conclusion that I would not find someone to repair this unit. D's came in and within a short test found the problem and assured me of a fix. They made the fix within 2 days as they needed to get a part and they also checked to see what the cost would be of the fix by putting in the control boarrd from the maker which was very high to the extreme. I now have a unit working and am very pleased."

Air conditioner equipment power in the U.S. is often described in terms of "tons of refrigeration", with each approximately equal to the cooling power of one short ton (2000 pounds or 907 kilograms) of ice melting in a 24-hour period. The value is defined as 12,000 BTU per hour, or 3517 watts. Residential central air systems are usually from 1 to 5 tons (3.5 to 18 kW) in capacity.
HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, on ships and submarines, and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
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
A mini-split system typically supplies air conditioned and heated air to a single or a few rooms of a building. Multi-zone systems are a common application of ductless systems and allow up to 8 rooms (zones) to be conditioned from a single outdoor unit. Multi-zone systems typically offer a variety of indoor unit styles including wall-mounted, ceiling-mounted, ceiling recessed, and horizontal ducted. Mini-split systems typically produce 9,000 to 36,000 Btu (9,500–38,000 kJ) per hour of cooling. Multi-zone systems provide extended cooling and heating capacity up to 60,000 Btu's.
I'll give props to HVAC Service for being available quickly and having Saturday and Sunday appointments. Tony fixed our air conditioner and was professional. So why only 2 stars? Because we sent the receipt into our homeowner association to see if we could get reimbursed for some costs, and the property manager said that we paid THREE times more than we should have. We got conned. I advise you to call HVAC Service, but also shop around and get other estimates. Learn from our mistake!

This doesn't mean air conditioning isn't right for your home. Some people are more sensitive to heat than others. Even if you can't justify the expense of central air conditioning, window air conditioning units will allow you to cool individual rooms tailored for your needs. If you work from home, you may want to put one of these units in your home office. If you have trouble sleeping with even modestly warm temperatures, you may want to put one in your bedroom. If you love to cook and spend long afternoons using the oven, your kitchen may be the place.
These guys came out same day to attempt to repair our unit. Unfortunately the repair didn't work (15 year old unit) so they came out early Saturday morning and did an emergency installation for us. They quoted us a fair and honest price when another company was dishonest with us and tried to take a lot of money from us for nothing. I will highly recommend these guys to my friends and family.
Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs (Photo 3). A blown fuse is a sign of a failing part inside the condensing unit. So don’t just replace it and think you’ve solved the problem. Instead, replace the parts we show here. Then install new fuses and fire up the unit. If it blows again, call a pro—you’ve got more serious issues.
