"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

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

Freon circulates through your AC unit in a closed loop, so ideally, all of it should remain inside your system and never need to be replaced. However, if your AC starts leaking Freon (which is common), you’ll need to top it up. Known as an AC recharge, the cost of adding refrigerant to your air conditioner depends on the size and type of the AC unit, as well as the type of refrigerant.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

When the capacitor fails, the AC unit can’t operate at all. The most common sign is the thermostat forcing the blower to turn on, but it only circulates room-temperature air. The AC unit also won’t make any noise or indication that it’s on. Sometimes, the compressor might hum as it attempts to work, but without any results.

Before a full shutdown, a faulty capacitor can cause your AC to struggle while turning on. The unit might also shut down in the middle of a cooling cycle.
