"When Sears was the only match on my HVAC project, I knew I was in trouble. Sears did not even bother to contact me so I called the plumbing company C Woods out of Tyler to see if they did HVAC installs. They did! they came out the next day to give me a quote and was able to install the system the following week. I gave them 4 stars for the work quality because they did leave dirt smudges on the walls and scratched the wood near where the old unit had to come from. I have them 4 stars on value for money because while it was probably a fair price, I just thought it was a little pricey. Overall, I would rate them 5*. We've had a good amount of work done at our home - we recently purchased a 42 year old home and my guess is none of the plumbing had ever been updated. So far so good! They are pleasant to deal with and their office staff is top notch!"

Heating and Air Conditioning FAQs, answered by experts

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it.
