Frequently Asked Questions
What do I need to know about permits and the new refrigerant for a 2026 installation?
All installations in Salisbury requiring electrical or mechanical work need a permit from the Town of Salisbury Administrative Office. Since 2023, new systems use A2L refrigerants like R-454B, which are mildly flammable. This mandates compliance with updated safety codes for leak detection, ventilation, and equipment placement, which your contractor must follow for a lawful and safe installation.
My unit is about as old as my house. Why does the AC keep freezing up?
A system installed in a 1974 home is roughly 52 years old. At this age, components like capacitors and refrigerant metering devices wear out, causing improper refrigerant flow. In Salisbury's moderate humidity, this often leads to frozen condensate lines as the evaporator coil drops below freezing. An aging blower motor in galvanized steel ductwork can also reduce airflow, which is a primary cause of coil icing.
Can my existing ductwork handle a better air filter for wood smoke and spring pollen?
Galvanized steel ductwork is generally robust, but forcing a high-MERV filter into an old system can cause static pressure issues. We must measure your system's airflow. For Salisbury's wood smoke PM2.5 and May pollen peak, a properly sized MERV-13 filter is effective, but may require adjustments to the blower speed or duct design to avoid straining the motor.
My Ecobee thermostat is showing an E1 alert. What does that mean for my system?
An Ecobee E1 alert signals a communication failure between the thermostat and your HVAC equipment. In Salisbury, this often points to a wiring issue exacerbated by system vibration or a failing control board. It can also indicate a safety lockout due to a prior fault, like a flame sensor issue on your propane furnace, requiring a technician to reset and diagnose.
My AC just quit on a hot day in Salisbury Village. How fast can a technician get here?
For a no-cool emergency, we dispatch from our office near the Salisbury Town Hall. Using US-7, we can reach most homes in Salisbury Village within 5 to 10 minutes. Our first step is to check for a tripped breaker or a clogged condensate drain switch, which are common quick fixes to restore cooling while we diagnose the root cause.
Our summer days get hotter than 85 degrees. Will a new AC still keep up?
An 85°F design temp means the system is engineered to maintain a 75°F indoor temperature at that outdoor condition. On hotter days, it will run longer but should still hold temperature. The newer R-454B refrigerant standard for 2026 offers stable performance in higher heat, providing a greater safety margin during our occasional peaks above the design limit.
With propane heat, should I consider switching to a heat pump in Salisbury?
Given Vermont's cold winters and high propane costs, a cold-climate heat pump is a strategic primary heat source. To manage the 17:00-21:00 utility peak hours, a properly sized system with a propane furnace as a backup for extreme cold provides the most reliable and cost-effective hybrid solution. Efficiency Vermont's $1,000 rebate further supports this transition.
Is it worth replacing my old AC just to meet the new 2026 efficiency standards?
The federal minimum is now 14.3 SEER2, but modern systems easily reach 18 SEER2 or higher. At Vermont's 0.21 per kWh rate, the upgrade cuts cooling costs significantly. The active Inflation Reduction Act rebates, with an $8,000 cap, directly reduce the upfront cost, making the payback period for a high-efficiency unit in Salisbury very attractive.
