"Our annual HVAC inspection went flawlessly. The technician was thorough, friendly, and gave helpful maintenance tips. System is running better than it has in years."
"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."
"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
Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs$5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:
Your unit is 10 years or older.
Your home is very humid.
The unit keeps cycling without producing cool air.
You need to repair the unit frequently.
Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.
Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.
Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.
Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.
