"I highly recommend Belle Air Services! From the first moment I called to get a quote, to the moment they finished the job, I could not have asked for better customer service, top notch work, and competitive pricing. They communicated with me all throughout the process, made sure I understood everything that would be done, were on time, protected my home and were clean. They even worked very well with my HOA (who is very tough!). And to top it off, they didn't try to up-sell me as other HVAC contractors have in the past. So pleased that I have found this HVAC company!!"

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

"Mario and his crew did an amazing job for my family. His prices are amazing with today times. Most companies want to charge over $20k for the same system I got with him. It's also the same warranty. The craftsmanship is amazing and the attention to detail is there. I would recommend him to any friends or family. I have the peace of mind that I picked the right contractor and company. I will hire him for my next hvac project."

Heating and Air Conditioning FAQs, answered by experts

It depends on the specifics of your warranty. The motor is likely not covered if you’re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there’s likely to be a strict time limit for this coverage.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.
