"Can't say enough about how good Josh and his company is. He gave me an estimate on a heat exchanger for my furnance and a complete system replacement. We went with the heat exchanger replacement. He came out and diagnosed a bad thermostat too for no charge, which he allowed me to replace which saved me some money. The estimate included the furnance tune-up and heat exchanger replacement. The estimate is what I ended up paying. Very nice, honest guy!"

"I was a customer of 1st Choice Heating a Cooling for 10 years or more. They installed a furnace in my prior home and just under 3 years ago installed an a/c unit in my current home. Had great service from them up until my most recent interaction. My a/c unit has a 10 year parts warranty and a 1 year labor warranty. The condenser fan motor went out. The part is 100% covered but the labor is not covered. I was charged $160 for a trip/diagnostics fee, then the quote for labor was just over $900. I was able to negotiate the labor down to $650 which is still extremely high given the repair took less than an hour to complete. Price gouging their customers by including filing fees and processing fees in with the labor fee for repairs where the parts are covered and labor is not. The owner was rude and condescending in his communications through the BBB. Claimed I was the problem since maintenance wasn’t done on my 2 year 10 month old a/c unit. I would not recommend 1st Choice Heating & Cooling."

"Needed to hook up my portable generator to the house. Mr Sparky was the first to call from angi so I asked for a quote. They came over very quickly and gave my wife and I a very good quote we thought. We didn't even get another, Slept on it, they called back the next day and we set set up a date. Mario showed up (very nice guy) . Said it would be a couple hours, and it was. They didn't need to turn off the whole house which was good and wired in a new electrical panel and plug on the outside. We tested it, and it worked perfectly. We are very happy.

Heating and Air Conditioning questions, answered by experts
While it’s possible to only replace an evaporator coil to keep your AC running, this could cause issues down the line. An AC system relies on the harmony between its condenser and evaporator coils for efficient operation. Replacing only one coil, especially in older units, can cause compatibility issues, leading to inefficiency and potential system breakdown.
As AC units near the end of their expected lifespan, investing in the cost for a new AC system is typically better than paying for individual component upgrades to avoid costly repairs and ensure optimal performance.
High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).
You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma.
If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.
The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.
