"Could not be happier, texted just last night for someone to check my AC unit not running. Said they'd be here 12-2pm today, quick turnaround with these 100+ degree days. Anyway the tech lands here right at 12, troubleshoots the issue in 15 minutes, and was done and gone by 12:20. It was a simple condenser connection issue so only paid the initial consultation fee...would definitely use and recommend these guys again for any of my HVAC needs."

I highly recommend them."

"Our experience with Romano HVAC was awesome juliano was very professional knowledgeable and informative he answered all of our questions and when it came time to actually replace the compressor he physically showed me what caused the old compressor to go out he was very courteous respectful and the price was less than half of what Bell Brothers heating and air had estimated and to make things even better for us he cleaned up his mess from the date of the estimate to the fixed state was less than 3 days it was awesome I would highly recommend Romano HVAC to anyone and juliano thank you you get a hundred stars from me if I could rate that"

"I replaced one HVAC unit through Lee s Air last spring. From the initial quote to project completion everyone I interacted with was professional and knowledgeable. They answered my questions and provided updates along the way, arrived each day on time, and cleaned up the mess as they worked. I not only replaced a unit, but had to have two vents replaced, all ducting replaced, and my return vent doubled in size. I was pleased with how quickly them completed the task and that everyone I spoke with, in person and over the phone, knew the details of the job throughout the process. I m now finishing a winter inspection with the company and cannot say enough about how great this company is to work with. I highly recommend Lee s Air to anyone looking for quality and professionalism in a business choice."

"First off Aaron showed up on time for initial meeting. He brought a wealth of information- listened to what we wanted and explained some very important aspects of the job to us. He answered all questions and offered good financing choices to make this happen. No hard sell, did not try to sell us oversized unit or brand that did not fit our needs. Very easy to contract with and extremely detailed. Booking an install date was easy and willing to work with our hectic schedules. They know their business and are the best company for any HVAC job."

"We had a nightmare story with another HVAC company. So when we talked with Spoors to set up service, we were very happy with their customer service and the technician was very professional and had a great attitude. WE WILL USE SPOOR'S AGAIN FOR SURE."

Heating and Air Conditioning FAQs, answered by experts

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

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.

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.
