Commercial HVAC Contractors in Bethel: FAQ
How often should commercial HVAC equipment be serviced?
Many building owners schedule maintenance at least twice a year, once before cooling season and once before heating season. Buildings with heavy use, such as restaurants, may need more frequent filter changes. Ask providers what interval makes sense for your equipment and how it is used.
Should I repair an older rooftop unit or replace it?
It depends on the unit's age, the repair cost compared with replacement, how often it has failed and whether parts and refrigerant are still easy to get. Ask each provider to walk you through both options and the reasoning behind their recommendation.
Does air duct cleaning actually make a difference?
It can help when ducts contain visible debris, construction dust, pest droppings or mold growth. It is less likely to change much in a clean, well-filtered system. Ask the provider to show you what is inside the ducts before any cleaning is agreed.
What should I check if the system stops working completely?
Look at the thermostat settings, the breaker or disconnect switch, and whether the filter is badly clogged. If those look fine, or you notice a burning smell or water leaking, shut the system off and contact a provider. If you smell gas, leave the building and call your gas utility.
Why does one part of the building stay hot while another stays cold?
Uneven temperatures often come from duct problems, closed or stuck dampers, poorly placed thermostats or equipment that does not match the space it serves. A provider can measure airflow and static pressure to narrow down the cause.
Will refrigerant changes affect a new installation?
New equipment is shifting to refrigerants with lower global warming potential, and older systems that use R-22 are increasingly costly to recharge. Ask providers which refrigerant a proposed unit uses and how that affects parts and future service.
