    We have been using A&S Nathan for years. They replaced our heating and installed new central air conditioning for us a few years ago and everything has worked perfectly. We continue to use them for our annual tuneup, which was done a couple of weeks ago. The technician, Dave, is true pro. He...

    Mike was fantastic! He arrived the day after I inquired about an appointment to address an AC issue. He was friendly and efficient! I appreciated how he took time to explain the issue and will be using his services for my heating needs. Highly recommend!

    Bought a foreclosed property with a dead furnace that was 32 years old and in really poor condition. Someone, obviously not a licensed HVAC person had put multiple air vents into the side of the coil to feed the basement, robbing the unit of efficiency. It was a total mess. I could have...

    This was our second time using Stanley Gelber & Sons, Inc. We will 100% use them again for our maintenance, or any issues we come across with our HVAC system. They are total pros and great at what they do. I would not consider using anyone else. I highly suggest using them if you have any...

    Sippin has been my oil company for 37 years and has also serviced my AC. They've always been reliable, including getting my heat back on in the middle of the night. They just finished the installation, and it was done extremely neatly (better than the system that was installed when the house...

    I felt confident after speaking with a number of providers so went ahead with the installation.  Everything went well, the workers were pleasant, all questions have been answered and the AC works great.

    Owner is a very down to earth, nice guy.  I originally had him come in to check my ac system last year after we first moved in and noticed the air was not coming out cold.  He quickly checked the system and told me we were low on freon.  He told me the pros and cons and I took the risk and...

Heating and Air Conditioning questions, answered by experts

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

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

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

No. With a ventless portable AC system, you don’t need to vent anything out the window—but it will be harder to circulate the hot air from the room without one, so you’ll need to come up with another solution, like placing a fan near a warm spot and facing it towards and open water to push the hot air out.

It's recommended to change HVAC air filters every one to three months. The frequency depends on factors such as filter type, indoor air quality, and whether there are pets or people with allergies in the household. Regular filter changes maintain proper airflow, improve indoor air quality, and ensure efficient HVAC system operation.
