"communication I found was poor. I felt I needed to reach out to them instead of them reaching out to me when I was the customer. at one point, figured I had not heard from them and was ready to just find someone else. I had to call them and when I did reach them wasn't even sure they knew who I was. they gave me a quote on 2 unit choices with nothing more than the price and the manufacturer, I had to call them to get more info on the units and do my own research. other than communication, things went well, clean, on time, polite, fair price,"

"I highly recommend Absolute Zero. Kyle didnâ t try to sell me upgraded equipment, he sold me what works sufficiently and what he would install in his house. I got a few quotes for the central AC and his price was the lowest. Installed in the attic that will be renovated into a room, he worked with me and planned and installed the air handler unit and all the ductwork where heâ d leave the center of the room open and did a great, clean job. He said the AHU upstairs and condenser unit outside would be quiet, I was shocked at how quiet everything was. He protected furniture and floors while they worked and left the house clean and tidy after leaving. Iâ m extremely pleased with the work and have already referred him to others."

"I cannot thank “Natural Breeze” enough for the fantastic job they did installing my new hvac system. I had previously committed to doing business with another hvac company during the heat wave who did a horrible and incompetent job with my hvac system. It was truly a horrible experience but thank god I was able to get out and terminate my contract due to their negligence. I was referred to Luis whom I reached out to and he responded to my emergency situation quickly. He is truly a reliable professional and having talked with him he is extremely knowledgeable and informative. He is a man who works diligently and has great morals and integrity. I am a dedicated as a life long member to Luis and his team, he goes far and beyond to make sure his clients are completely satisfied and his prices are definitely reasonable. Thankyou Mr Luis and to your crew for the exceptional work that u have provided. I highly recommend this company if you are looking for a A+ hvac contractor ."

"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"Highly recommend Allined Mechanical! Billy and his team were able to come over and assess our existing central air system pretty much right away. He was super informative, not pushy (which I have dealt with in the past). Replaced our compressor and got our system up and running in no time. Great customer service, we will be using him for all of our hvac needs from now on!!"

Heating and Air Conditioning FAQs, answered by experts

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

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.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.
