"New Era HVAC was amazing! I own a small business that has a very challenging environment to work around. Jared was extremely professional and minimized the disruption to our routine. We have large warehouse heaters. A few years ago we had one installed by another company. They left a huge mess, took 2 1/2 days to do the work and had no regard for disrupting our business. In contrast, when Jared replaced the second one he was done in one day, left the area clean and neat when he left, and was extremely accommodating with us. We have also had a tankless water heater replaced by New Era and had the same experience. Professional, honest, and reliable - you will not find a better company out there!!"

"My experience with Clean Air Genie was great. They were professional and knowledgeable explaining everything to me clearly and provided pictures and videos before and after the work was done. My air ducts were pretty bad (hadn’t been cleaned in 10 years) and they were able to get them very clean and sanitized. I appreciate that their prices were transparent and fair for the work. I will definitely recommend!"

Heating and Air Conditioning questions, answered by experts

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

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.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.
