"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."

"Smart Heating and Air Conditioning was the most professional, friendly, and knowledgeable company I’ve worked with. From our first contact, we felt like we were working with family. Our furnace went out and the techs and installers were all so amazing with keeping us all informed, especially Susie who works in the office. But what really showed me how great this company was, is that they saw our handle to our screen door wasn’t functioning and they were so kind to offer to fix the issue. They fixed it in 5 mins. You don’t see this type of generosity anymore, so we appreciate that! Our furnace and air were replaced for a great price and we couldn’t be happier. I would highly recommend this company for your heating and conditioning needs!"

"The TASK service professional was prompt, friendly and explained very thoroughly what he was going to do. He was very thorough and kept me apprised of the vent and HVAC conditions he noted. After the vent system cleaning was done I noticed a big improvement in air quality > I could breath easier and deeper, the air in my home was fresh and I've also noticed that my home heats up faster and stays warmer at lower thermostat settings. I highly recommend TASK."

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"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

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.
