"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

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
