"The tenant called him a couple of months ago for something he had one previously, but because he's a good guy, and we had done something six months ago that was very expensive, whatever went wrong this time he just must've fixed. The tenant said she was going to call us back to let us know he fixed it, and there was no contact again, so I'm assuming everything was fine. Our tenant just knows to call him if it's anything to do with heating and air conditioning. He usually does a perfect job and works with you if something goes awry to make sure it's right. I would use him again. He is right there."

"Global Comfort installed a full HVAC system in my home; 7 new runs for air, new AC unit, new furnace and a new Nest thermostat, all electrical needs. Rudy and his team are respectful, efficient, punctual, competitive in pricing. Rudy walked me through running the system for its first time and explained all the stuff for a brand new system in a house that never had AC. I'm very thankful for the work they did. Highly recommend because their customer service is top notch."

"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."

"Rasu was AMAZING! I had a very unusual clog in my dryer duct and he stayed and worked on it! He took the time to make sure my dryer was working correctly as well. He went above and beyond. I would recommend him over and over! Am using him for my air vents and chimney sweep services. Heâ s honest, fair, ckeaned up after the job was complete, polite and his price was extremely fair ."

Air Conditioning questions, answered by experts

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

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.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).
