"It was wonderful working with Chris/ Nextgen today. He did a great job explaining everything I need to do with my unit, what to expect, and all the benefits I can get from it. I really appreciate the time he took to answer my questions and make sure I understood everything. I just want to say thank you, Chris, for all your help! I look forward to a great installation! I’m scheduled for tomorrow"

"Mr. Charlie and Mrs. Angela were great, understanding, and professional of our situation without having any hot water for a week. I will be happy to recommend them again, they were very courtesy about not messing up our carpet with their equipment. He quoted us a price over the phone and didn't go over it, he will be used again by us."

"Chris’s crew was outstanding. They cleaned our crawlspace and didn’t encapsulated it. They were placed ductwork where it was needed. The photographs are clear documentation of a home improvement. I think the cost was reasonable to high, but I have nothing to compare to. In the end, I am quite pleased. The dehumidifiers have lowered the humidity in the living space and eliminated a musty smell that had been present. I can recommend him with no reservation."

Heating and Air Conditioning questions, answered by experts

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.
