"First to call after I inquired on Angi for recommendations. Promptly made an appointment and provided an estimate. Very pleased with the price, arrived on time, completed the HVAC duct replacement the same day. Also replaced the moisture barrier in the crawl space. Will highly recommend to friends and family."

"Anthony was awesome and went over and above for us on every time we have needed his service. Even helped us with warranty items. I would highly recommend Honest AC and he is extremely knowledgeable. Affordable also - one doesn't feel like you are being over charged. Fair to the customer. Wish him the best success for the future and will use service again and will recommend to anyone. Thank you Anthony for your help. Life saver."

"I found Worley H&C from Angi website. He reached out within minutes and repair was completed SAME DAY. This was for one of the rental properties i own. I was out of state. I will MOST DEFINITELY keep this number for future! Absolutely no regrets and Absolutely no negative issues with this company. Its a challenge to get ethical, honest repairs with companies these days. This company was a blessing for me."

I’ve Been in the cleaning industry basically all my life. I love what I do, I love seeing the results of my work but more importantly the impact that I make on people day to day. Being able to walk into a clean home after work or a long day in general is a feeling that goes beyond measure and I’m sure everyone is striving for that.

Heating and Air Conditioning FAQs, answered by experts

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.
