"Air conditioning stopped working on a Wednesday. David sent out a technician that afternoon to confirm the compressor was bad. The next day a crew of 3 came out in late afternoon and installed a new A/C unit (old one was 28 yo) and a new furnace (old one was 30 yo). I stuck with RUUD/Rheem due to good experiences. The crew was efficient (3 hours to do both installs), the A/C is working great with cooler air and more forceful blowing, and they briefly checked the furnace operation also. My old unit was a 10 SEER operating probably at a 7 efficiency lately and my new unit is a 14.3 SEER. I found everyone polite from the owner to the workers, addressed my needs, and answered my questions. I still use my old thermostat which is Honeywell programmable while the one they gave me was Honeywell non-programmable. And BTW, David said I probably would raise my thermostat a degree or so with the new unit, and I did without any loss of comfort. Finally, the price was the best I found."

"Excellent service, we had an emergency where our AC unit was failing. Alex responded immediately and on time, he was able to diagnose the issue, a faulty capacitor and get our AC back up in a few hrs. It’s so hard to find dependable people who know what they are doing so I’m glad to have them as my first choice"

Customers say: Super punctual

"I recently hired Pure Air Ducts to clean the air ducts and dryer vent in my home, and I couldn’t be more satisfied with the results. From start to finish, they were professional, efficient, and thorough. The technicians arrived on time, explained the process clearly, and took great care to protect my home by covering the furniture. They were courteous and answered all my questions, making sure I understood what they were doing. The job itself was done with precision, and I noticed an immediate difference in the airflow and cleanliness of the air. They even showed me the lint build up in the dryer vent. The entire process was smooth, with no mess left behind. Overall, Pure Air Ducts exceeded my expectations. Their attention to detail, professsionalism, and quality of work make them an easy recommendation for anyone in need of air duct and dryer vent cleaning. I’ll definitely be using them again in the future!"

"????? Excellent furnace service ? highly recommend Caleb with Always There Air did an outstanding job servicing our furnace. He was punctual, professional, and extremely thorough in explaining what he was doing and what to watch for going forward. You can tell he genuinely cares about doing the job right, not just rushing through a service call. He took the time to answer all of my questions, made sure everything was running efficiently, and left the area clean when he was done. It?s rare to find a technician who combines strong technical knowledge with great customer service, but Caleb absolutely does. I wouldn?t hesitate to use Always There Air again and will specifically request Caleb for future HVAC needs. Highly recommend."

Air Conditioning FAQs, answered by experts

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

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.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.
