"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

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.
