"On time, neat, effective. Technicians were professional, personable and flexible. I gave a "B" on cost because I may have done better if I shopped around but having the company that was installing the HVAC install the electrical as well was a good convenience and one-stop shopping."

"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

Heating and Air Conditioning questions, answered by experts

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
