"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!"

"Our house is 60 years old. We have lived her 42 years, this the first time we have had the ducts cleaned. 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. Ventcenters.com we put them in all our registers"

Air Conditioning FAQs, answered by experts

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.
