"I waited a year and a half to file this review to be fair about my comments. I was at first put off by the fact that the son came over to give an estimate and he wrote about 15 words and a 16,000 dollar estimate with no description of the equipment or what all was included. He was strongly recommended by a friend so I went ahead and approved heat and air and new ductwork in my old 1954 3 bedroom house. He had an adequate crew to do the work and his father was very friendly. The work was adequate but after the job I found a lot to be desired. They left a lot of debris in the attic like old ductwork for me to remove. At every place they removed my freshly installed attic insulation to install new ducts and return duct they left all the insulation thrown about and nothing covering the areas around the ducts so I had to lowcrawl through the attic under all those ducts and reinstall all that insulation, which at my age (70 yrs old) that was no pleasure I can assure you.

"There was no category for Vent/Duct cleaning so I placed under Central A/C repair. Good customer service, flexible scheduling around wife's medical appointments. Technician and office sent updates as to arrival time. Technicians were masked and put on shoe protectors without being asked. Worked quickly and efficiently. Good team."

"Project: Install a new HVAC for upstairs. Kevin came Friday afternoon to evaluate our needs and quoted me the pros/cons/prices for two different brands of HVAC. I selected the Goodman units and we agreed on installation to begin the following Tuesday at 9:00 a.m. with an estimate of 5 hours for completion. He arrived a few minutes early on Tuesday and completed the installation an hour ahead of schedule. He and his helper were very professional, courteous and helpful. The results have surpassed my expectation."

Heating and Air Conditioning questions, answered by experts

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.
