"This is the 2nd clbk to Ralph for the same issue, to clear the clogged pipe that was backing up into the toilet, he came, tried snaking and when that didn't work he had to leave to rent a piece of equipment in order to clean out the waste pipe as he obviously does not have proper eq. when I called to check how it was going as this is a rental property, he said it was all set, then he realized that now the sink lines was backing up, so the clog was not resolved. I asks him to call me before he left & follow up, when I checked on the status he said it was resolved, but he had to leave to pick up his son & left the waste he cleaned out on a piece of plastic under the waste pipe in the bsmt. Asked when he was coming back to clean up, he replied he doesn't know, and was annoyed that I expected him to clean up after he finished the job! I would Never Hire Seaside Plumbing Heating and Cooling out of Fairhaven, unless you want to keep calling him back to fix the same issue and leave a mess!"

Heating and Air Conditioning questions, answered by experts

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.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.
