"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.

"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

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

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.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.
