"Of all the people I've had work on my home renovation in the last year, these guys were my favorite. Prompt, professional, honest, and reliable. When Duke came to give us the estimate, my 2 year old daughter wanted to give him a hug before he left which is unprecedented. That pretty much sealed the deal for us. They were also far and away the most reasonable quote we got. Even a friend quoted us $1500 more for less work. The installers were on time and knew their stuff. The install work is top notch as well. Everything in place and looks well put together. I highly recommend them to anyone looking for HVAC work."

"We had to upgrade our old furnace and AC so we decided to look around and call a couple companies to come and give us a quote. We decided to go with Smart heating and air, their prices were upfront and fair. We got our systems installed in a very professional manner. All the technicians wore masks, they used foot covers and put down cloths to protect our floors. After they installed they tested both ac and heater to make sure it was working. The cool thing about it is that we can control the temperature with our nest app without getting up with our phone. I love this bc I was always forgetting to turn off our system but now I can do it anywhere. I totally recommend this company. We will use them for any HVAC related concerns."

"Perfect Star sent a technician out to assess my HVAC issue. and it turned out to be my ducts had been torn apart by critters getting into my crawl space and trying to nest. I got a crawl space cleanup crew to address that problem but Martin (my HVAC technician) told me about an air purifier that could be installed to my HVAC units. He installed those for me right away and they are working great."

"Jorge, Angel, Ishmael, and George were fantastic. Jorge was honest and straight in the initial conversations. He gave me multiple options for systems and their functionality. When I made my selection I was given a very fair price for the work that was to be done. He was very helpful in acquiring good financing that bested my Credit Union and Bank. The work was done quickly with great attention to the fine details. I now have an efficient and functional HVAC unit. If you need repairs or a replacement HVAC system you could not do better than selecting Elite Heating and Air for your job. I'm telling all my friends that if they need any work done - "I've got a guy"..."

"These guys are just excellent! I made a few mistakes before I got lucky to find New Millennium HVAC. They were professional from the beginning to the end. Jose did a thorough job, cleaning the dryer vent. It was not a straightforward issue and I was afraid that we’d have to open the wall to cure the blockage. However, Jose was able to fix it. He’s an experienced professional excellent at his job, trustworthy and overall great to deal with. I’m a happy customer for years now and will rely on these guys for any HVAC related issues."

Heating and Air Conditioning questions, answered by experts

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

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.
