"I used their website feature to request a tech for residential A/C repair for the following day. But I received a phone call from Cytech a couple of hours later asking if I wanted service earlier as they had a tech available at that time, which worked out even better for me. The service call and repair was completed in 45 minutes after tech arrived in a efficient and professional manner. Tech even went above and beyond the repair and fixed up a couple of minor issues without charging me anything additional. I'll will be calling them again in the future should I need HVAC services!"

"Great thermostat installation service. The technician was punctual, professional, and made the entire process easy to understand. The new thermostat works perfectly, and they took the time to ensure everything was properly configured before leaving. Excellent customer service and quality work. Highly recommend!"

"We were very impressed with the work and knowledge Chris and Leslie provided to us while servicing our house. We originally had scheduled for a cleaning to have a smoke smell removed from prior renters and while they were here they brought other issues to our attention. Long story short, all issues were resolved in a professional and timely manner. Not only did they get the smell out of our house they provided us with vital information about what they did and why they did it. Also, they provided us with information to help us maintain the air ducts to prevent further issues. We will definitely be using their services again."

Heating and Air Conditioning FAQs, answered by experts

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.
