"I received a call back from Doneright HVAC within 5 minutes of posting on Home Advisor. Garret arrived to my home in 30 minutes with his technician (as promised.) They were friendly, knowledgeable and professional. He was thorough in trying to pinpoint the exact problem and offer the most cost effective solutions, while still informing me of the inevitable need to replace my 12 year old, failing system. He even identified a faulty outlet in my attic where the units heavy plug had been attached for over a decade, and had caused some type of electrical failure resulting in Black scorch marks on both the outlet and the plug which could very possibly have turned into a house fire had it not been identified. He immediately jumped in his car and drove all the way to Home Depot to go get The necessary materials to change the plug\ outlet to a breaker protected switch, and rewired it to prevent further danger, and hardly charge me a thing for it! To sum it up; I would recommend Doneright HVAC to anyone needing HVAC service of any kind and will be keeping them as my permanent HVAC professionals! Thanks for everything guys!"

Heating and Air Conditioning questions, answered by experts

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

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.

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.
