"While we didnt hire them, the company contacted us right away and were available within an appropriate timeline. The coordinator was friendly and reassuring and had we not had someone lined up I would have felt very comfortable moving forward with this group. They were transparent about their pricing and displayed confidence in their capabilities."

"Andrew knocked this install out of the park! He replaced an incredibly inefficient hot water heater with a hybrid hot water heater, ran the condensate line through pipe straps screwed into drop in anchors along our basement wall with the cleanest looking final result that surpassed every expectation I had. He was very communicative well within the budget and will be our go to for any future work we need as long as we live in this area!"

Heating and Air Conditioning FAQs, answered by experts

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

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.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

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.
