"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."

Heating and Air Conditioning questions, answered by experts

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

You should schedule a full-service AC inspection at least once a year to ensure it works properly. During this time, your local AC repair pro will check:

  • Safety components, such as carbon monoxide leaks

  • Cooling components, like coolant levels 

  • Electrical components, such as inspecting fuses and wiring

  • Complete system services, like flushing the drain line

While you can DIY some aspects, like changing your air filter, it’s imperative that you call in a pro to inspect your AC for you. Your air conditioner has refrigerant that could be hazardous to your health if not handled properly, so it’s best to let a pro with experience take on this job.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
