"Unique replaced my 20 year old high velocity air handler, condenser, and separate mini-split systems. Overall everything looks and works great! I was impressed by the dedication of their team - working in my attic in 95 degree heat, installing a smart thermostat for me, and even removing/killing a giant wasp nest that was in the eaves! They also accommodated my request to remove the condensers a few weeks before the new install, so I could do some landscaping work. Price was also quite reasonable. Definitely recommend."

"A great experience from start to finish. I found Kingdom Cooling on Angies List and the owner (Gerry) was very responsive and personable and explained to me in detail what he thought was going on after explaining the problem. He was able to give me a very accurate ballpark estimate which was very reasonable. Scheduling and timeliness of the repair was also done very quickly and efficiently. I would definitely recommend Kingdom Cooling for Service for sure!"

Air Conditioning FAQs, answered by experts

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.
