"A-maze-ing. These guys were GREAT - I won't be calling anyone else in the future. First, they spoke to the woman in the house exactly as they did to the man - no dumbing it down for the ladies. Physically showed me what was going on and explained it well so I understood what was needed and why. They let me know which repairs needed to be done immediately and which could wait - no hard upsell at any point. They set reasonable expectations for what improvement I could expect with each step. Polite, friendly and helpful, showed up well within the estimated window. Before each visit I got a text with the name and picture of the tech who was on their way and a phone call from them to confirm. In 5 visits I worked with only 2 point people, meaning they weren't having to start from zero every time someone walked in. They charge by the job, not the hour, meaning the work was done quickly, but with quality. I had someone I know take a look at the work and they said everything looked very well-done. After each step they followed up with me by phone to find out if I wanted/needed anything else. In short, I had a shockingly great experience with them and can't recommend them highly enough."

Heating and Air Conditioning questions, answered by experts

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.
