"ARS is the HVAC service provider since we bought this house from the builder. Furthermore, ARS was the HVAC sub during its construction. This visit was to remove a worn-out humidifier, replace it, and replace a UV bulb. Jonathan was the technician. He provided excellent service."

"Excellence in HVAC and the human spirit. That is truly hard to find in today's corrupt world. Christopher is an exceptional young man, and exuded every good quality of an upright character. I didn't know how to reach Miller's, so I left an AI automatic generated message, emailed Austin, and waited for a call back on the weekend mind you! Austin saw his email, and staff saw the AI, and Austin fielded the call to Christopher who called me and promptly came out. I can't say enough about the heart of this business. They follow this biblical teaching in the Bible: Philippians 2:3,4,5 Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself. Let each of you look out not only for his own interests, but also for the interests of others. Let this mind be in you which was also in Christ Jesus. Need I say more? May God bless your business for the kindness and generosity you have shown."

Heating and Air Conditioning FAQs, answered by experts

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

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.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.
