"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 live in Dallas, Texas. I have had Enoch Air out before => once for an electrical issue; another time to have them install a window AC unit. This latest plumbing issue being the third time these guys have come out => I have absolutely nothing but superlatives to say about Enoch Air, Electric & Plumbing. Their entire operation is just a pleasure and a huge relief. They do business the OLD SCHOOL way. They are actually concerned with the customer’s predicament - unheard of in this day and time. Customer service is non-pareil’ and they are very prompt. And no, I’m not related or co-joined to Enoch Air in any shape, form, or fashion. Their prompt, courteous, and reasonable attention is much appreciated by the wife and this ole’ boy. Thank you, Enoch Air!!! *This review was migrated from an affiliated account on Angi with an original submission date of 10/12/2019."

"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!"

Air Conditioning FAQs, answered by experts

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.
