Franklin sits within the Boston metro area, where winter temperatures drop to 22 F and summers climb into the low 80s with significant humidity.

The area is served by seven contractors holding an average rating of 3.9 across 449 reviews, and three of those companies maintain 24-hour availability for emergency calls.
Annual maintenance costs for a single rooftop unit range from $550 to $2,200, while small business contracts covering spaces under 5,000 square feet run between $1,100 and $5,500.
