"Mike and his team did a great job with installation of a complete new HVAC system involving a ducted system on the 1st floor and mini splits on the 2nd floor (this set up best accommodated our house for function and zoning). Their experience and knowledge was demonstrated by their well planned work and installation, including working around existing conditions such as tight crawl spaces, as well as coordination with existing plumbing, electrical, structural components, etc. They coordinated and were accommodating of requests for equipment and vent locations. And they started and completed the work as promised. I would highly recommend them."

"Mark and helper climbed their ladder outside to the Soffit under the roof overhanging. They cleaned the vent and ran a brush all the way down to the clothes dryer. Now my clothes are dry and the amount of dust has increased due to the opened pathway. Any dust that came outside was cleaned up. Great job. Thanks!"

"Problem: Fractured drain pipe inside basement foundation wall. Outstanding work by all involved. Marybeth was very courteous on the phone. Ryan arrived on time, assessed the requirement and quoted an estimate of cost. Done Right's price was similar to the other two bids. All were about $1K higher than expected; but probably reasonable in light of the +4 hours of hard labor involved. The following week. Colin and Jamiel arrived on time, assessed the situation, and quickly went to work. They manually excavated +3 feet of dirt and clay between the vent pipe and outside wall, and removed the fractured section of drain pipe. They discovered the main drain line had settled deeper into the ground, which probably caused the pipe to split inside the basement. They expanded the original opening in the foundation wall to align and connect the old and new pieces, applied hydralic cement to fill the gaps, refilled the hole, and cleaned up the entire work areas, including the front entry way. Jamiel and Ryan did an outstanding and professional job, working expertly together as a team. Unfortunately when it rained heavily three days later, there was water seeping through the concrete patch. Two days later, Done Right sent Ryan and Adam to correct the issue. They chished out the cement and completely resealed the entire area. Fortunately, when it rained again, the new cement patch worked fine with no leaks. Adam and Ryan did an outstanding jod. Done Right honored its three year warranty for parts and labor. We will call Done Right again for our future plumbing needs and recommend to neighbors for their quality workmanship, commitment to excellence, courtesy, and professionalism."

Air Conditioning questions, answered by experts

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.
