"Great Experience. I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"Project: Repair or Service a Central Air Conditioning System Sam from Liberty is GREAT! I had my AC recharged earlier this year and they charged me $170 per pound for freon!! This is the dirty little secret..You (and they) can buy it for $29 a pound on the internet....so I lost the first round with SmartHouse??? overpaid for 2 pounds plus service call plus labor.....A month later. I accidetnally cut a hole in my line in the garage.lost 5 pounbds of freon.I called all the AC companies I could find and asked them how much per pound the cheapest was $85!! some for $150!! Oh they all lie to you "the price is going up" R22 freon will be outlawed in 2020 our costs have gone up" BS! they all want to stick you for maybe an extra $600 wihtout you knowing it if you need 5 pounds. They are all con artists and liars . I checked with about 5 companies and got the cheapeast bid of $1000 ish and most around $1300! I told them I knew about the mark up on freon and they all did their little tap dance. I finally found Sam on Craigslit under services rendered...Called him he said he would give me a fixed price he knew all about the markup scam! He got the job done for $525!! Sam is a hard worker and didint show up til 7pm and had one more call that night after me! He welded my pipe vac'd the system and charged it up as good as new! While most of these AC company rackets try to get rich off of each job. Sam has a different philosophy he gives a fair deall and justs works harder than everyone else and makes it up on volume. Also he is a one man company so he has very littel overhead...One slight complaint..he hinted that he would be over by 4:15 PM but didn't make it til 7pm as he has other jobs he said were"ahead of me" I suspecet he got a job that he would lose if he didnt take it right away and could tell I would wait....Just a guess....Anyway it was worth the wait ...they say you can get Good Fast OR Cheap Pick 2. Oh and here is a warning ..If you ask for after hours service from any of the established crooked companies get ready to pay $249 a pound for freon!!!! Less"

"The 3 Mustache Pledge! Schraer Heating and Cooling deserves every bit of praise I can give! I called them about a worrisome noise coming from my system — one that I could only describe through a few rather vague and comical sound effects. Despite my less-than-technical explanation, their technician quickly understood exactly what I meant, found the issue, and had it fixed in no time. Their professionalism, responsiveness, and ability to solve the problem so efficiently (and with good humor!) made the whole experience stress-free. I’m so grateful for their excellent service and expertise. Highly recommend Schraer Heating and Cooling to anyone looking for honest, skilled, and friendly professionals! I will definitely keep my maintenance agreement in full force and effect!"

"I highly recommend AAA home services. They installed a brand new HVAC system and the entire process was trouble free every step of the way. I have had them out to service the system twice a year and the scheduling to do so is easy and the service has been excellent. AAA home services has always communicated well and I have had them do exceptional plumbing work including the installation of a hot water heater. Thank you AAA home services."

He explained the costs to me prior to performing the work and it actually ended up costing LESS than estimated. Honest and professional! I will definitely keep their number on my fridge and recommend them to my friends and family."

The air in the house just seems lighter, the biggest thing is we have a black glass top entertainment center in the den. U could clean and 2 days later it was dirty again. We had this done2 weeks ago, it just now needs cleaning. We are very happy with the results. Would highly recomd it. Also vent centers is a filter company with wonderful filters for your air ducts.

Air Conditioning FAQs, answered by experts

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.
