It's important to ensure that an HVAC company performs proper combustion and draft testing on furnaces to ensure the safety and efficiency of your heating system. While it may be challenging to determine this information before contacting them directly, there are a few strategies you can employ to gauge their professionalism and expertise without causing offense:
Check online reviews: Look for reviews or testimonials from previous customers of the HVAC company. While not all reviews may mention combustion and draft testing specifically, positive feedback about their thoroughness, attention to detail, or commitment to safety can be good indicators.
Certifications and affiliations: Check if the HVAC company holds relevant certifications or affiliations with professional organizations. For example, technicians certified by organizations like North American Technician Excellence (NATE) or the Air Conditioning Contractors of America (ACCA) are more likely to be well-trained and knowledgeable about proper testing procedures.
Ask about their process: When you contact the HVAC company, you can inquire about their general approach to furnace maintenance and safety checks. You don't have to ask them directly if they perform combustion and draft testing, but you can ask about their standard maintenance procedures and whether they ensure the safety and efficiency of the system.
Seek recommendations: If possible, ask friends, family, or neighbors for recommendations of HVAC companies they have used in the past. Personal referrals can provide insights into the quality of service and whether proper testing was performed.
Remember, it's important to prioritize the safety and efficiency of your furnace. While it's understandable that you may not want to offend the HVAC company, asking questions and gathering information beforehand can help you make an informed decision and choose a reputable company.
