"Pure Air provided excellent air duct and dryer vent cleaning services for our two story home. Orlington and his father were extremely professional and thorough. They provided a complete breakdown of the pricing for their services prior to starting the job and their pricing was very reasonable. We will definitely use them again when we get our air ducts and dryer vents cleaned next year."

"I had a leak somewhere so I called New Era and they sent a technician out the same day I called. I had my condenser replaced at price I could afford. Very friendly and professional! I would definitely recommend new era for any air conditioning repairs or install"

"Mechanical Comfort Systems installed a new heating and air system when my upstairs (where all the bedrooms are located) system went out in the heat of the summer on a Thursday (left for work and it was working... got home and it was 90 degrees upstairs). I had another HVAC contractor out before calling Mechanical Comfort Systems and their proposal was significantly more expensive for a lesser system than I received from Mechanical Comfort Systems (the efficiency of the system was an upgrade from existing, and other company quoted replacement with same efficiency as existing). The system was replaced quickly (on a Saturday), and the installers were great, very professional. They cleaned up after themselves, and did a great job. During the freeze this February, I had a water pipe freeze and burst. Mechanical Comfort Systems came out the day after, even though driving conditions were still terrible and all my friends in similar situation were being told it'd be several days to a week before a plumber could come unless they paid some ridiculously expensive emergency fee... I recommended Mechanical Comfort Systems to three other people I knew that also had frozen pipes burst, and they all had them come after fix theirs after I gave them Mechanical Comfort Systems information. I strongly recommend Mechanical Comfort Systems to anyone needing any plumbing or HVAC work. I'll definitely use them again... although I hope not anytime soon ?"

"Our AC went out yesterday evening and this morning at 7:30am my sister called an AC repairmen, Legacy Air Heating & Cooling, they answered the phone right away, made the appt for 10-12 today! Repairman showed up on time, fixed the clogged drain, checked the unit over, and told us a price, then finished fixing the problem, unit was low on freon, and then went into the attic to see if any ductwork was loose or off of the ceiling vents. Josh is a very professional serviceman. Best AC Repair experience I have ever had!"
