"Alex was really nice and knowledgeable about our broken AC. We did pay the $89 service fee for the evaluation. What caught me off guard was the quote for a new Amana HVAC Unit - 26K! I mentioned that I need to get a few other estimates before committing. In response, Alex said that most people find out that his prices are competitive. I would have preferred that Alex said, "Great idea! That's a lot of money and it's always a good idea to get a 2nd opinion"...or something like that. After consulting 2 other family-owned businesses with stellar reviews, we were quoted prices that were 10 to 12 thousand less than One Hour. The equipment was the same, if not even higher efficiency. Definitely shop around before committing."

"had such a great experience with HighPoint HVAC! The entire process was seamless and incredibly easy from start to finish. I was able to schedule an appointment right away, and the team arrived exactly on time. They were professional, friendly, and took the time to explain everything clearly. After finishing the job, they left the space spotless; you’d never know any work had been done. Their quality of service and attention to detail really stood out, and the pricing was very fair. I’d highly recommend this company to anyone looking for reliable, high-quality HVAC service"

"I would suggest you drop all other services and go with this one only. This service man is far beyond the skills and service of all others. I had one show up in car and a back pack. He looked at and said he would send a quote ?????? My furnace is out , its late and the temp outside is 0. Tony Bertolini repaired it less then a hour with no parts. This is a man that knows his S!!! and is more than worth his charges.When the weather starts to warm up I will call him to install a new one . [ I will call no one else .}"

Heating and Air Conditioning questions, answered by experts

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

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.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.
