"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."

As a result of this experience I plan to have Air-Tech take over the maintenance on my main HVAC system."

"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."
"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!"

He was very professional & friendly man,and Highly recommend them if AC/Furnace issues"
Heating and Air Conditioning questions, answered by experts
While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.
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.
Here’s how AC professionals will clean your AC coils:
Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.
Remove the faceplate.
Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.
Use a soft-bristled fin comb to remove stubborn caked-on debris.
Use the vacuum hose to suck up any extra debris.
Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.
Let the solution sit for at least 15 minutes.
Gently wipe away loosened grime and debris with a microfiber cloth.
Reattach the faceplate, plug in your AC system, or turn the breaker back on.
There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs.
