"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

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.
