"I highly recommend Charlie Nelson's company next level heating and air conditioning. He had to make an extra trip to Home Depot for $2.00 part and he did not add that to his original quote of $309. The $309 included his labor and time. That's what he originally quoted and he stuck to it."

"It's been a couple months since Zach with McDonald's Home Solutions analyzed our air-conditioning needs and had Potts and Vince install the Mitsubishi heat pump and duct work. They were amazing and very hard working. The system is working great and makes a huge difference in the comfort level of our house. It's extremely quiet. It operates like a whisper and we hardly know it's on other than the house is cooler. I checked the energy use of the system against our solar panel productions and it hardly makes a difference. It's amazingly efficient. I strongly recommend anyone considering installation of an HVAC system to use McDonald's Home Solutions. They're the best."

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"Rasu was AMAZING! I had a very unusual clog in my dryer duct and he stayed and worked on it! He took the time to make sure my dryer was working correctly as well. He went above and beyond. I would recommend him over and over! Am using him for my air vents and chimney sweep services. Heâ s honest, fair, ckeaned up after the job was complete, polite and his price was extremely fair ."

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best!"

"Rick and his team were awesome. They were very thorough, put everything they moved in my garage back and Rick made sure to have me check both the heater and AC once installation was complete. He also installed my smart thermostat for me. I would highly recommend Rick and his team."

Air Conditioning questions, 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.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.
