"Mark and his crew did an outstanding job. Mark took before and after photos of the HVAC system to show the difference. Not only does Mark conduct himself in a very professional manner, his crew is also very respectful and professional as well. From start to finish this work was a definite value for the money. I will be using Patriot anytime the need arises."

"Had the entire AC/Heating system replaced. Took about 2 days because the inside equipment was in the attic. Prompt, courteous and knowledgeable. The owner DID NOT try and sell me on an upgraded system as most other HVAC companies would do. The owner only recommended what was actually required. Highly recommend this company."

"Mark and Corey were both very prompt, courteous, and professional. They presented fair pricing and superior installation on the 2 (two) HVAC systems that they supplied for my wife and I . They went the extra mile with them showing up to complete the install prior to a Hurricane headed directly at our area. I highly recommend Sensible Air Solutions for all of your needs, whether it be a full HVAC installation or HVAC service/repairs."

Heating and Air Conditioning questions, answered by experts

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.
