"Anthony was awesome and went over and above for us on every time we have needed his service. Even helped us with warranty items. I would highly recommend Honest AC and he is extremely knowledgeable. Affordable also - one doesn't feel like you are being over charged. Fair to the customer. Wish him the best success for the future and will use service again and will recommend to anyone. Thank you Anthony for your help. Life saver."

"I found Worley H&C from Angi website. He reached out within minutes and repair was completed SAME DAY. This was for one of the rental properties i own. I was out of state. I will MOST DEFINITELY keep this number for future! Absolutely no regrets and Absolutely no negative issues with this company. Its a challenge to get ethical, honest repairs with companies these days. This company was a blessing for me."

I’ve Been in the cleaning industry basically all my life. I love what I do, I love seeing the results of my work but more importantly the impact that I make on people day to day. Being able to walk into a clean home after work or a long day in general is a feeling that goes beyond measure and I’m sure everyone is striving for that.

"I cannot speak highly enough of David and his team. When I got a moderately high radon reading on the home I was selling, I had to take care of it quickly so that my closing could go through. David worked me into his schedule and came to my home the day I called. He was delightful, did a thorough inspection, and gave me an estimate. I subsequently got an estimate from another vender, and it was $1,000 more! Not only that, but David had figured out a way to perform the remediation without installing unsightly pipes either on the inside or outside of the house. This involved him working in a very shallow attic space to run the pipes up through the heating ducts, but he was happy to go the extra mile. On the day of the work, David and his wonderful assistant Ryan arrived on time, and spent the better part of a day installing the system. They were convivial and professional without being the least bit instrusive  - I enjoyed the experience! After the installation, David explained it to me in detail, and left a radon kit so that my buyers could check the new levels. Not suprisingly, my buyers are more than happy with the results. If you need to have this job done, call David. You won't regret it!

Heating and Air Conditioning FAQs, answered by experts

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.
