"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

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.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

Yes, through thorough cleaning and inspection, optimizing functionality, and reducing energy use.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.
