"Will and Rob showed up at the house and the appointed time and started right at it. The old a/c, furnace,duct work, wiring, and gas line were gone in no time. When they started the install, took their time to get everything perfect. Constantly checking for level and plum of all units, ducts, plumbing, and even wiring. Explained what was going on and why they were doing what they were doing. Both Will and Rob very friendly and extremely knowledgeable about HVAC. I worked in the plumbing wholesale for 20 years, so I know a bit about was going on. The new technology is amazing. They installed a 96 percent efficient furnace with a 16 seer a/c unit by Amana. Came with a lifetime warranty on the a/c compressor and furnace heat exchanger, the two main components.
They did an excellent job. All the old units were taken away and site was completely cleaned cleaner than before they started. Will even filled out the rebate form from the electric company for me.
I will definitely hire Giant again and again!

Heating and Air Conditioning questions, answered by experts

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.
