"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
To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.
While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:
When purchasing a high-efficiency system, your energy bills will be lower in the future.
You may be eligible for special offers from your local energy company.
Depending on the system, you may be eligible for HVAC rebates and tax credits.
Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs.
The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.
Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.
