"Top-notch installation! The new HVAC system is super efficient and the crew explained everything clearly. They handled the entire job with care. I feel the temperature difference immediately?very satisfied!"
"AC Dave is a skilled and trustworthy HVAC company that does quality work at a competitive price. I had an aging four ton system that was on its last leg. My funds were tight at the time, so they suggested installing more efficient ducting to extend the system’s life. That was three years ago, which allowed me to save for the inevitable expense of replacement. And when that time came, I was given a comprehensive estimate and the installation went smoothly. They also did a follow up to tweak the system for maximum reliability. AC Dave is a small company, so you may not get next-day service, but they will work with you and stand by their work. In today’s less and less neighborly world, that is a real asset."
"My interaction with Air-Tech went very smoothy. Alex Fish, the customer representative was very professional and easy to work with. He provided a clear and detailed proposal , with options, before leaving the site on his first visit. Alex stayed in communication throughout the project. As a result of this experience I plan to have Air-Tech take over the maintenance on my main HVAC system."
"This review is about Air Duct Professionals and I want you to know that I finally found a company that was honest and professional. Because when I was at the end of my wits trying to figure out who was telling me the truth, I called Ed Mack the owner and he was reassuring that my home was not that old to be having all these problems. He referred me to a website for the Air Duct Cleaners Association and read about what air duct cleaning really does. So I had Air Duct Professionals come out to the inspection and they have an actual HVAC guy on their staff. Immediately looking at how new and well maintained our air system was in the attic, he told us those other companies were trying to scam us. Air Duct Professionals did a great job cleaning out all of our air ducts and dryer vent and cleaning up after themselves. I whole-heartedly recommend this company for their professional work and honesty."
"Can't recommend Dean and Efficiency Air enough. After getting quotes from 4 different companies we were lucky enough to try one more and I couldn't believe how much Dean knew about HVAC systems and all of the different brands, as well as being even on top of future HVAC government regulations and rebates! They do business the old fashion way and will work on the job until you are satisfied. Dean and Efficiency Air are what HVAC Legend is made of."
"Had a new HVAC unit installed at my rental home. Was walked through the bid process and the work was done very quickly. Appreciate the customer service I received. Everyone was professional and answered my quetions."
"My HVAC unit stopped producing heat so I called the folks at around the clock. They offered to come out the same day and after taking a look up on our roof determined it was a faulty control board. We talked a little about the lifespan of the unit and that while it was probably going to need to be replaced in the next 5 years or so, it made more sense to simply replace the board today. So he scheduled an appointment for the following day to come back with the replacement board. 1 day later and 15 minutes of work and I have heat again."
"Great job, Workers are great and they know HVAC. They are a great team and very nice people. Owner is very sincere & reliable. He will work with you on the best equipment...... you get what you pay for.!!!!!!!!"
"HD Mechanical got all our commercials units back in order. They provided excellent customer service and we will be using them from now on for all our commercial and residential HVAC needs!"
"Haroon Sayed was great. He came by, assessed my issues with the furnace, thoroughly explained everything to me and provided me with my options on repairing or replacing the system.
He was very professional & friendly man,and Highly recommend them if AC/Furnace issues"
Heating and Air Conditioning questions, answered by experts
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.
A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.
Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.
Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.
For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.
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.
It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.
