"Alex was really nice and knowledgeable about our broken AC. We did pay the $89 service fee for the evaluation. What caught me off guard was the quote for a new Amana HVAC Unit - 26K! I mentioned that I need to get a few other estimates before committing. In response, Alex said that most people find out that his prices are competitive. I would have preferred that Alex said, "Great idea! That's a lot of money and it's always a good idea to get a 2nd opinion"...or something like that. After consulting 2 other family-owned businesses with stellar reviews, we were quoted prices that were 10 to 12 thousand less than One Hour. The equipment was the same, if not even higher efficiency. Definitely shop around before committing."

"Absolute 1st Choice will absolutely be our 1st choice. He deserves more than 5 Stars. He found problems that were more serious than the one we hired him to fix. He explained what needed to be done and offered to do it. He made no attempt to "upsell' us on anything. He stayed until the project was completed to our satisfaction. He was well organized, professional and trustworthy. Trustworthiness is the most important thing, without that I might as well have tried to fix it myself. I know that wouldn't have ended well. If you hire a company with a fleet of fancy trucks and prime time TV ads, you can be fairly sure that the service tech will , at some point, magically transform into a a salesman. Thank you, Home Advisor!!!"

"Tony was very easy to work with and accommodating. I had narrowed my choice to 3 firms. Elevation was not the cheapest nor the most expensive but I felt most comfortable with Tony and believe he offered the most value. My air conditioner was installed today, I hope this will be the start of a great (and cool) relationship."

"had such a great experience with HighPoint HVAC! The entire process was seamless and incredibly easy from start to finish. I was able to schedule an appointment right away, and the team arrived exactly on time. They were professional, friendly, and took the time to explain everything clearly. After finishing the job, they left the space spotless; you’d never know any work had been done. Their quality of service and attention to detail really stood out, and the pricing was very fair. I’d highly recommend this company to anyone looking for reliable, high-quality HVAC service"

"A-Moonlight provided timely and professional service. They were able to diagnose issues with my A/C and furnace quickly and explained the issue and their proposed solutions. Brent made me aware of my options for repair and what services were necessary and what was not. They were able to install the parts I purchased and service my furnace and A/C within a few hours. They got everything working in one trip and charged about 1/6th of what a competitor was asking. I would highly recommend A-Moonlight for any residential HVAC needs and I will be hiring them in the future should I need any other HVAC services."

Heating and Air Conditioning questions, answered by experts

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.
