"As a realtor, I often encounter homes needing new HVACs or repairs. I constantly recommend Triad Mechanical to my clients because they are fast and affordable! Last week, I had a competing business give me a quote for a new AC for the basement. They quoted $7000. I immediately called Kaylee at Triad to see if they could give us a quote as well. They came out the next day and within fifteen minutes my seller received an estimate with almost $2500 savings! Needless to say, we will be moving ahead with Triad!"

"Hired these guys to replace my original heating and A/C unit. They seem to have done a good job--it works fine. Furnace unit has filter and housing is a little wonky, but it seems to work. They also installed a fancy thermostat which can be read and operated by my phone over the internet. I wasn't too impressed with the thing at first, but I'm away for periods and I've been very pleased with it."

"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."

Heating and Air Conditioning questions, answered by experts

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

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.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.
