"I had 24 windows replaced by them. The owner is friendly and pleasant to deal with. I had about 20 issues with the job, ranging from minor annoyances to major problems. The owner agreed that all of them were valid. The major problems included things like the installer not showing up, them ordering the wrong products, and taking 7 weeks to do the job that was scheduled to be complete in 2 days. On a 5 star rating system I would rate them as: Value-4, Communication-2, Quality-3, Execution-2. If you are not a discerning individual and have plenty of time on your hands, you would probably be fine with them"

"Our furnace would not turn off, so we first tried putting new batteries in our programmable thermostat. However, doing that did not fix the problem. Next, I called Parley’s PPM Plumbing, Heating, and Cooling for some help. David, who answered the phone, was pleasant and helpful, and he made an appointment for us for the next day within the 8 am to 10 am time period. Meanwhile, we worked on reprogramming the thermostat, which was a bit tricky, but the furnace began working properly again. We thought we would have the Parley’s furnace specialist check our furnace anyway, just to make sure there were no other problems with it. Robert Winget, the furnace specialist, arrived within the proposed time frame and was very knowledgeable and professional. He checked out our furnace and found no problems with it and there was no charge for the service."

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
