"This company does not answer my phone calls. We never knew when they planned to arrive to work on our installations. We ordered three air conditioning units and three heating units. The last unit was a heat pump instead of a regular air conditioner but I allowed them to install the unit since we were told the fan would run when the temperature was below 32 degrees.. Lennox shipped the wrong unit. We were not familiar with a heat pump. The unit fan runs constantly and the installer will not return my phone call."

"Project: Install a new HVAC for upstairs. Kevin came Friday afternoon to evaluate our needs and quoted me the pros/cons/prices for two different brands of HVAC. I selected the Goodman units and we agreed on installation to begin the following Tuesday at 9:00 a.m. with an estimate of 5 hours for completion. He arrived a few minutes early on Tuesday and completed the installation an hour ahead of schedule. He and his helper were very professional, courteous and helpful. The results have surpassed my expectation."

"Seemed good but unable to report fully on quality of work done since I've never had my chimney"whipped" as opposed to swept before. I was told it was superior to "sweeping", don't know that. Apparently service man "did not have proper shoes to go on my roof to sweep from above. I was a little appalled by this. I will see how it works when I have my first fire. Assume work is guaranteed. NICE GUYS Marianne, West Fork"

Heating and Air Conditioning FAQs, answered by experts

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with.
