"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

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.
