"I was unable to use the big deal due to the fine print/details of the service.  The company installed my HVAC system originally.  They are very professional and polite everytime I speak to them."

"A-maze-ing. These guys were GREAT - I won't be calling anyone else in the future. First, they spoke to the woman in the house exactly as they did to the man - no dumbing it down for the ladies. Physically showed me what was going on and explained it well so I understood what was needed and why. They let me know which repairs needed to be done immediately and which could wait - no hard upsell at any point. They set reasonable expectations for what improvement I could expect with each step. Polite, friendly and helpful, showed up well within the estimated window. Before each visit I got a text with the name and picture of the tech who was on their way and a phone call from them to confirm. In 5 visits I worked with only 2 point people, meaning they weren't having to start from zero every time someone walked in. They charge by the job, not the hour, meaning the work was done quickly, but with quality. I had someone I know take a look at the work and they said everything looked very well-done. After each step they followed up with me by phone to find out if I wanted/needed anything else. In short, I had a shockingly great experience with them and can't recommend them highly enough."

Heating and Air Conditioning questions, answered by experts

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.

But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.
