"I'm very happy with the work performed by this company plus the technician explained to me in detail of the work he was going to do as well as the correct way the dryer vent should have been installed before as the the exhaust vent was connected to the lower vent instead of the higher vent, saying that connecting it to the higher vent gave it more room for the lint to collect before it started clogging up the exhaust. The air duct cleaning was also conducted professionally and I have no complaint about their work. I would hire them again the next time my heating and cooling ducts needs cleaning. I'd recommend them to my friends."

"they got to my home when they said they would. the tec check out my ac unit ,he said i needed a relay he replaced it and the unit ran the same as before. he would not reinstall the old relay even though the new one did not make my unit work. he said the unit was low on coolant how did he know that when the unit would not keep running? i am mad at myself for not speeking up enough when the tec was at my home. he did not give me a bill, I still do not know what i was charged. After my service call a manager called me. We spoke for some time and he agreed with me and give me a credit for the service call. A hired them to install my new AC system. Two men came on a Saturday they worked very well togeather they installed the new system and cleaned up after them self. I am very pleased with there work. The new system works great. And the price was inline with other AC companys."

Air Conditioning FAQs, answered by experts

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
