"Highly recommend. Found this company last year on Angie's List and this is the second time using them. I was in a pinch as the A/C went out and we have a little baby. I called and they got someone out the same day. Jeff was great...knowledgeable, friendly and answered a lot of questions! Got the unit working again! These are my go-to HVAC guys!"

"This was our first time needing an HVAC service for our house (AC unit issues) and Ish, Nick and Genaro did a fantastic job! I met with Ish first to diagnose the problem. He is super knowledgeable and was able to answer all my questions confidently and thoroughly. He was honest in explaining our options for our budget. He gave me estimates for multiple different scenarios I asked for and I never felt pushed into the more expensive option (and I am typically quite a skeptic when it comes to these types of things)! He also really took his time while at my house. I didnâ  t feel like I was rushed or that my questions were a bother to him. We decided to replace our whole unit and him and his team were able to come back just three days later! The install was smooth, they cleaned up all the work areas really well, and the whole team is very personable (and dog friendly, which I appreciate)! Overall, our experience was the best case scenario, and we will be using Ish and his team for all our future AC/Furnace maintenance!"

"Francisco and his team (Ralph) did absolutely great work. If you are reading this review, book them. Your search for an HVAC contractor can stop here. I am a new home owner and had a lot of questions about my home. I am an engineer and wanted to understand the exact details of the repair.. They took the time to answer all of my questions, I had a few HVAC contractors estimate the work and they were the only ones that did not try to upsell. They explained the work to be done before and during the job. Afterwards they gave recommendations about future work that I plan to do. I would absolutely do business with them again and you should too. Note: I have no relation to them at all. I did not know the two of them before this job. I would absolutely do business with them again should their services be needed. It was a pleasure learning from them and they did quality work repairing the original issue they were contracted for. Additionally, they went above and beyond the contract to fix several other issues that occurred / were found during the job. This is the team you want to hire for your HVAC needs. They were fast, did quality work, were on time, had solid communication, and were reasonably priced. Francisco / Ralph, if you you ever need a referral, let me know. Again, great work guys. 10/10"

"AWE promptly responded to my work request and kept me informed about my appointment status. Peter came to perform the work. He was very thorough and even discovered that the HVAC contractor on our new home installed 2 furnaces: a current year model as well as a prior year model that was more prone to breakdowns. Provided great information and would definitely hire again. Thanks!"

Heating and Air Conditioning FAQs, answered by experts

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.
