"Great service all around from Bob Jensen. Free in home estimate with no pressure sales tactics. When it came to the installation, it was nice to know that they use their own crew, they do not subcontract out the work, so you know what you're going to get. On the day of installation, the sales person came also to ensure that we all understood what was going to happen. The install technicians, Tony and Sammy, took time to ensure that everything was done correctly and answered all the questions I had. I would highly recommend this company for any of your HVAC needs."

"We hired Airmercia Air Conditioning & Heating to evaluate our heating system and propose repair solution. Ryan was very professional and punctual. He did not make any force sales. He just offered various repair and replacement solutions and explained pros and cons for each one. We decided to replace our furnace and duct system. Ryan did an excellent Job!! I highly recommend him for your HVAC project."

"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"We just had a new HVAC system installed in our home in Aliso Viejo. The contractor was Cool Air Technologies, Bill McIntosh, (714)863-0626. We were very impressed with the new unit put in the attic and back yard, the workmanship, the professionalism, the quick response time to get our appointment, the testing of the new units before they left, the lessons for us on how to use it, and the complete clean up and hauling every piece of the old unit away when they left. They even installed new air vents/registers in every room and air filters! Very impressive and highly recommended to everyone! [*** Link removed ***]"

"My 26 year old central air system went out on a Thursday night.  I called Liberty Friday morning and the sales manager for Liberty came to the home the same afternoon. After discussing details, options and answering all of my questions, I accepted their contract to replace my 5 ton ac and furnace. The price was fair and all of the work was completed the very next Tuesday.  Part of the installation involved enlarging the air return space under the furnace closet.  This improvement, along with the higher efficiency AC unit should keep me smiling this summer.  They also provided a programmable thermostat and set it up so the house will always be at my preferred temperature.  I won't even have to switch between cooling and heating when the seasons change.  I couldn't be more pleased with the outcome and will definitely call Liberty for any plumbing problems I might have in the future.

"Unfortunately, I needed an HVAC company to fix my AC during a heat wave. Most companies were 5+ days out before they could even diagnose our problem. Called 3 highly visible companies, from their marketing, who said they wouldn't even work on our unit. I went with a referral from a neighbor, mistake. This company took a week to get to us then the tech went MIA for 5 days with no contact when he said he would be back tomorrow with parts. Won't mention their name as there could have been multiple uncontrollable reasons why. I then did a lot of research on different companies across multiple review websites (including Angies) and Excel Air stood out. Once I spoke to the office staff, great experience, they had a tech out to our home in 2 days with our problem diagnosed. Our tech's name was Lucas who was efficient with his time, talked me through what was going on and gave us our estimate which we were happy to move forward with. Lucas fixed our problem in under 20 minutes. Me being me, I watched each step and saw the quality work. He even put in a fuse to ensure the same problem didn't happen again to our transformer. Once he fixed everything and got our new thermostat power, our AC has been working perfectly ever since. I'm now a really big supporter of Excel Air. Their office staff worked with our insurance company after hours and actually updated us (what company does this these days) the entire way. I can't tell you how impressed I was from their office, Lucas and most of all their successful resolution of our problems with our AC. Thank you Excel Air!"

"Technician Angel came on time. He first cleaned our HVAC unit, checked the wirings & parts & performed tests to ensure the unit is running according to standards. He inspected the Air ducts, vents even the attic. He explained everything and showed us the pictures that he took & the results on HVAC heating and cooling tests that were done. Overall a very good job done by Technician Angel I told him to come back after 6 months. Already recommended Airtime Heating & Cooling to my neighbor. 5 STARS"

Heating and Air Conditioning questions, answered by experts

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

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. 

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.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.
