The problem with most "pros"? Too many bad habits. It's easy to get swept away in the day to day monotony, even for those that call themselves "pros". When it comes to hiring a heating and cooling technician, nobody wants to deal with being treated like a sale rather than a person, the use of scare tactics instead of education, or someone who just wants to get to job done quickly instead of correctly. All our HVAC pros go through 5 years of HVAC schooling, for a total of 10,000 hours of on-the-job training. And it's not just technical training either; it's training that focuses on you, on making you feel comfortable every step of the way. We will roll out the red carpet for you, both figuratively and literally. Red Carpet Treatment During every visit to a home, we lay out an actual red carpet to prevent any additional mess. But what may be even more important than just protecting your home is making sure you feel like you've received the best in customer service.

Heating and Air Conditioning questions, answered by experts

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

Signs that your air conditioner capacitor is malfunctioning include a smell or smoke coming from the unit, a humming or banging noise when it starts, the system shutting off randomly, higher energy bills, and no cold air blowing out of the unit. Additionally, if your capacitor is bad, the air conditioner may not turn on at all. 

Yes, there are ventless portable air conditioners that don’t have exhaust hoses and don’t require venting. Instead, they have a water reservoir and cooling pad, which add moisture to the air to make it feel colder. Ventless portable AC units work best in dry climates since humid areas already have a lot of moisture in the air and can’t absorb much more.

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.
