"we had a Bosch boiler hot water combo system installed in the spring of last year for $9500. We used the heating system on some cool days and nights, so it seemed to do the job of heating our home. This year is the first time we have used it for the entire winter. If the temperatures are mild the system works okay. If the temperature drops below 30 degrees it will not heat our home. We were able to keep the house warm thanks to our pellet stove. In Hine sight, We wish we would have stayed with the conventional boiler system for about half of what we paid for this inadequate system. buyers know what you are getting into before you buy."

Heating and Air Conditioning questions, answered by experts
Clean the filter regularly, inspect seals, and store the unit properly during the off-season.
Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.
Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.
One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.
After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.
The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.
