"The primary reason I hired the contractor was to clean the furnace ductwork. The vacuum equipment they used left a layer of dust in every room in the house and on every surface including the carpet, bedding etc. I've spent 3 days dusting and vacuuming the carpet after the work. I think Steven and Sons is a very good company if you hire them to repair or replace your furnace, however they don't have the proper equipment for duct cleaning. "

"Paid a premium for a new HVAC system, and the A/C has had issues every summer since installation. Service calls have been frequent but only resulted in temporary fixes. Most recently, the system failed completely, and despite promises of follow-up and support, the company has been unresponsive and disorganized. Communication is poor, and I?ve been left without A/C during extreme heat. Very disappointed in the lack of reliability and accountability. Would not recommend"

"Highly recommended and I will be calling next time I need help. My heater wasn't heating so I called around. Dylan was able to come straight over, less than 2 hours after I called the house was warm. Luckily it was a simple fix, no parts needed (a spider had built it's web in there), so the whole repair was covered under the $89 service fee. Dylan was respectful of me and of my home. AND he told me they work on swamp coolers, which is sort of hard to find these days."

"Curtis diagnosed the problem and fixed and verified the furnace is working correctly. He did this in just a little more than 30 minutes. His 18 years of experience was well worth it. He took apart the gas valve area and found between the gas valve and the orifice to the burner had a spider web obstructing the gas flow. The furnace works well now. Curtis was very professional and honest. Thank you, Curtis, for a great job. I had another company check the furnace last week, but the tech they sent did not have the experience to correctly diagnose the problem."

Heating and Air Conditioning questions, answered by experts

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

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.

Mini-split air conditioners are less expensive to run than central air and are considerably more energy efficient. You can run the heating or cooling units in individual rooms and turn off the units in the rooms you aren’t using. This method allows you to save about 30% off your energy bill compared to a ducted system.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.
