General information only

Everything on HeatCoolVerdict is general information for homeowners. It is not professional engineering, legal, tax, insurance or financial advice, and it is not a diagnosis of your equipment. Only a qualified technician who inspects your system can tell you what is wrong with it and what it will cost to fix.

Safety

Heating and cooling equipment involves natural gas, high voltage, combustion gases and pressurized refrigerant. Do not open sealed panels or attempt gas, electrical or refrigerant work yourself. Handling refrigerant requires federal certification. If you smell gas or a carbon monoxide alarm sounds, leave the building and call your gas utility or 911 from outside.

Prices and figures

Price ranges are quoted from the published sources named on each page, on the date the page was last updated. They are national or regional figures, not quotes. Your price depends on your equipment, home, location and the contractor. Sources can change or contradict each other.

Calculators

The repair-or-replace calculator and the AC size calculator apply simple rules of thumb to the numbers you enter. They do not model energy savings, local prices, building code or the condition of your system. Do not buy or decline equipment on their result alone.

Licensing

Licensing requirements change. Always confirm on the official state page linked from our guide before you rely on them.

Contractors

We do not endorse, recommend, guarantee or vouch for any contractor. A match through this site is an introduction, not a recommendation.

How content is produced
