FAQs
These quick answers cover what counts as an HVAC emergency, what to do first, and what to expect when you call MasPro Service.
What counts as an HVAC emergency?
An HVAC emergency is any issue that creates a safety risk or makes the home or building unsafe to occupy. This usually includes no heat during freezing weather, no AC during extreme heat, burning smells, gas like odors, electrical issues, major leaks, or a system that shuts down unexpectedly. Call or contact Mas Pro Service for 24/7 emergency HVAC support.
Do emergency HVAC services cost more?
Emergency service can cost more because it involves after hours scheduling and rapid response. The best way to get an accurate number is to call with your symptoms and equipment type so we can set expectations before dispatch.
What temperature is considered an AC emergency?
Is a burning smell from my HVAC system an emergency?
Can I reset my furnace or heat pump myself?
What should I do if I smell gas near my furnace?
Leave the area, do not flip switches, and contact the gas utility or emergency services if the smell is strong. Do not operate the HVAC system until the source is confirmed safe.
What if my HVAC system is leaking water?
Water leaks can damage floors, ceilings, and equipment. If water is actively dripping near electrical components, shut the system off. Leaks are often caused by a clogged drain, frozen coil, or condensate pump issues.
What HVAC system should I use in an older home?
If your home is older and doesn’t have a current HVAC system, a ductless mini-split may be great for heating and cooling your home! Visit this blog page “Modern HVAC Solutions for Older Homes in Washington” to learn about more HVAC options for older houses.
How often should I service my HVAC system?
Your HVAC system should be serviced at least once a year. MAS Pro recommends servicing it twice a year for standard systems.
This is because filters can collect things like pollen, dander, and skin particles! Updating your air filtration system and performing regular maintenance can help prevent allergies and illnesses in your home. We’ve outlined the benefits of regular maintenance in more detail in this post, we want to keep our customers and friends always well informed. Feel free to call us and ask about our products today!
