Went without any major problems. Heater was attached to a water soft machine, one of the connectors broke and they bdid not have one, had to order and return to fix. This did not cause any problem, a bypass was made, and the heater was able to be used.

It was done as promised.I had checked out the different brands and this band has a good rating. What sold them is it was the best price for heating with air. We were replacing a propane heater and the air was basicly a bonus.

Heating Oil questions, answered by experts

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives).

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

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.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year.
