We’re Still Adding HVAC Pros in Petersham.

Ask the technician for the age of the system, what failed, the cost of the repair, and the cost of a replacement, in writing. A repair on a system near the end of its life can cost more over time than replacing it, but only the quote and the system's age can tell you.

The make and size (capacity) of any new equipment, what is removed and what is reused, labour, permits, the warranty on parts and on labour, and the start and finish dates.

In many states, yes, and handling refrigerant needs a federal certification. Ask to see the licence number and check it with the state board. On Pros Around, "Licence verified" means we matched the number to the board's record on the date shown. We do not check insurance.

Ask how the pro worked out the size. A good answer refers to a measurement of your home (a load calculation), not only to the size of what is there now.

The price depends on the size and difficulty of the job. Some pros publish a starting price on their listing. Ask two or three for a written quote that says what is included, and compare the scope as well as the price.

Only customers who contacted a pro through Pros Around can review them, using a link that works once. Pros can reply but cannot delete a review, and reviews are never sold. An admin hides a review only if it breaks our rules, and the reason is recorded.

By the plan a pro has chosen, then a Featured badge, then review quality. A higher plan can place a pro higher; between pros on the same plan, reviews decide. Anything paid for is labelled.
