"HIGHLY RECOMMEND! Did much research on companies 1st b/c I was aware of scams with duct cleaning. But this company is very legitimate professional - techs and receptionist, all the way around! Top quality service! On time and will answer any questions and explain it all in great detail? very polite and professional. And yes, they will take photos throughout if you want to see exactly the differences of before and after. I had bought a 1959 home which had never been cleaned. See my before/after photos. Before, I kept having to wipe off my counter tops a few times a day because they always felt gritty. After the duct cleaning, they stay clean now - A HUGE DIFFERENCE! The guys were awesome and went above and beyond by also helping me carry a heavy appliance from upstairs to my basement. Very nice guys! They cleaned up any mess before leaving, like they had never there. You will not regret using their service. Lower Price than others too! Thanks Danny & Cameron! Great Work!"

Heating and Air Conditioning FAQs, answered by experts

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

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.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.
