"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

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.
