"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"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

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

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.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it. 

You should schedule a full-service AC inspection at least once a year to ensure it works properly. During this time, your local AC repair pro will check:

  • Safety components, such as carbon monoxide leaks

  • Cooling components, like coolant levels 

  • Electrical components, such as inspecting fuses and wiring

  • Complete system services, like flushing the drain line

While you can DIY some aspects, like changing your air filter, it’s imperative that you call in a pro to inspect your AC for you. Your air conditioner has refrigerant that could be hazardous to your health if not handled properly, so it’s best to let a pro with experience take on this job.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.
