"Jorge, Angel, Ishmael, and George were fantastic. Jorge was honest and straight in the initial conversations. He gave me multiple options for systems and their functionality. When I made my selection I was given a very fair price for the work that was to be done. He was very helpful in acquiring good financing that bested my Credit Union and Bank. The work was done quickly with great attention to the fine details. I now have an efficient and functional HVAC unit. If you need repairs or a replacement HVAC system you could not do better than selecting Elite Heating and Air for your job. I'm telling all my friends that if they need any work done - "I've got a guy"..."

"Perfect Star sent a technician out to assess my HVAC issue. and it turned out to be my ducts had been torn apart by critters getting into my crawl space and trying to nest. I got a crawl space cleanup crew to address that problem but Martin (my HVAC technician) told me about an air purifier that could be installed to my HVAC units. He installed those for me right away and they are working great."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

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

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.
