"I have a two-story single family house. Last year, Druziako HVAC replaced my first floor AC with a Carrier heat pump. I quoted 5 companies, and Druziako was honest and gave me best pricing. The heat pump worked great in summer and winter. This year I hired them again to replace my 2nd floor AC. The whole team are friendly, helpful, and very patient. Installation went smoothly and quickly. I cannot be happier with the pricing and quality of the work. I will recommend them without any doubt. Thank you very much!"

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"From receiving the quote to the installation and servicing NETR has been extremely professional and great to work with on this renovation project. The installation went very smoothly and every person on their team had a lot of experience. Further, the team was able to solve a number of tricky problems with our installation (such as running the electrical behind the walls, drilling a hole through the roof for the pipe, concealing the pump in the back of the closet). The installation happened on time and on schedule. I would highly recommend them to anyone looking for HVAC services at home."

Heating and Air Conditioning questions, answered by experts

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.
