Benefits of Safety Checks

Mechanical systems powered by natural gas including your heater, air conditioner, and water heater involve combustion of fuel, heat and oxygen to properly operate. Because your system relies on combustion to generate energy, it is crucial to inspect the components to ensure a smooth and safe operation. In addition, safety checks on your HVAC system and water heater help to:

  • Ensure your system is running efficiently
  • Prevent costly repairs
  • Extend the lifespan of your system
  • Provide peace of mind
  • And more!

Difference Between a Safety Check and a Maintenance

With a safety check, we do an inspection of your heating, air conditioning, and water heater to check and ensure specific components of your system are running safely. With a safety check, if we come across an issue with one of the components, we will let you know and provide you with a solution to address the issue. With a maintenance, we do a thorough evaluation of your heating, air conditioning, and water heater and perform extra steps to ensure your system is running at peak performance including: changing your filter, replacing U.V. bulbs, cleaning your unit, tightening wires, and more!

The prompt only allowed me to choose one option. But the whole team was professional, helpful, on time, and provided me with all the information I needed on the quality products that were installed.

I’ve been with Guthrie & Sons since 2008. They installed my new unit and have serviced it twice a year ever since. Something has changed and not for the better. Most notable in communication. After a service visit I received several quotes for further work, mind you no call made during the visit to notify me of these items. New quotes also include a $95 visit fee! If I’m already paying for the initial visit why would you leave without speaking to me if more work was recommended? I called the number on the email that specifically said “if you have questions”. Needless to say the person who answered “Amy” couldn’t provide one single thing of information regarding my visit and I have to speak to the technician. She was politely dismissive and just kept referring me to the technician. This isn’t the level of service I’ve had in the past and not sure I can stay if this is the new standard.

They offered a very competitive price for a much higher SEER unit and they were efficient, clean and informative completing the removal and install of the new unit in one day. I am also very happy with the Bosh unit they recommended and installed.
