Frequently Asked Questions

What should I expect to pay for Thermostat Installation around Exeter?
It depends on the actual fault, the system's age and type, and whether it is an after-hours call. A worn capacitor and a failed compressor are very different prices. Insist on an itemized estimate rather than a single all-in figure so you can see what is driving the number.
How often should I have the system serviced?
Once a year at minimum; twice, heating in fall and cooling in spring, is ideal where both ends see demand. In Exeter, a pre-winter heating check is the single most valuable thing a homeowner can schedule.
How do I know a quote is fair?
Get the estimate itemized, ask what happens if the first fix does not hold, and be cautious of anyone quoting major work before diagnosing. A second opinion is cheap insurance on any large repair or replacement.
Is it worth repairing an older system?
A useful rule of thumb: if the unit is past ten to fifteen years and the repair is a large fraction of replacement cost, replacement often wins, especially in NH, where long, hard winters and short, mild summers keep the system working hard. A straight contractor will show both options with real numbers.
Why are some rooms hotter or colder than others?
Uneven temperatures usually point to ductwork, leaks, imbalance, or undersized runs, rather than the unit itself. It is one of the most common and most overlooked issues, and a good tech checks airflow before blaming the equipment.
