K&S sent a technician the same day with no extra charge and the technician stayed until the central heating worked again. He replaced the igniter and the circuit board. It was pricey (approx. $550) but he also could have charged more, considering a family cannot live without heat in MN. The...

Tierney Plumbing came out promptly at the scheduled time, assessed the situation (relocating & replacing 1 water heater - replacing a 2nd water heater.) They were very thorough and courteous and said they would get back with me that week. When I didn't hear from them after a week, I called and...

Jim was very prompt and reasonably priced. It would have taken me much longer to fix the door myself and I didn't feel like risking a trip to the ER (these springs have very high tension). I think it only took Jim about an hour plus he oiled the garage door so that it sounds much quieter. I was...

Heating Oil questions, answered by experts

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.
