"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."

"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!!"

"Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

Heating and Air Conditioning questions, answered by experts

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.
