Plumbing and Boiler Heating

"Hired this place to install new plumbing lines, install toilets, showers, etc & install a water softener during a remodel. They flooded the house TWICE due to botched work by MT city plumbing. The first time was because they didn’t hook up the softener right and that caused our basement to flood. 3 weeks later, our upstairs flooded and the basement AGAIN. This was due to incorrectly installing a water line to a toilet. When we brought the first flood to their attention and asked for insurance info to file a claim, they accused us of trying to benefit from them? Wow really? We had thousands of dollars worth of personal items destroyed and all the flooring and drywall we had just finished installing had to be torn up. Then, to have it flood again 3 weeks later is not okay. This “business” is NEVER a place I would recommend to anyone. Would give ZERO stars if I could."

Heating and Air Conditioning questions, answered by experts

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

The cost of a new HVAC system is roughly $7,500 but will vary by the type of HVAC unit and the size of your home. If you only need to replace your AC, it can cost between $2,200 and $5,500; replacing your furnace costs $3,200 to $6,000.
