"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 should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.
