Had Airstream Technologies come out and replace our entire heating and A/C (HVAC) system. All I can say is Angie and her crew were absolutely top notch! They went over and above in many ways for us. To include fixing things that weren't their fault (from original installation) to managing our...

The price I paid on the heating and air was a great price compared to other companies and he offered a 2 year warranty versus a 1 year. He wants to make sure the units go through all of the seasons. Brian is always responsive and willing to help. I gave him a "good" on the responsiveness only...

Heating Oil questions, answered by experts

An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.
