"It was covered under warranty. They actually installed our HVAC and it just wasn't cooling and it was a real simple thing that he was able to fix me up with. I have know them and used them for a long time. They are always prompt. They are very professional in what they do. They pick up after themselves. Very helpful in the information that he provides and making sure that any issues we are dealing with, he takes care of."

"Great! I told them I would give them a call to come out and do the furnace this Fall. They were very nice, very knowledgeable and I would use them again. She told me I could get the furnace without the carbon monoxide, I could probably get it for about $69, which is pretty standard I think for what most people have around here. I've seen some people advertise for about $69. I also know the carbon monoxide, because I had one, this gave me a second one, those things are not cheap. They are $20 - $25 to buy one, a decent one. I thought the price was very fair. Their work was good. I was very pleased with them. They got a hold of me fine, it was me that dropped the ball. It wasn't them. They got a hold of me. I had the holidays coming up and I forgot about it. They didn't have to, but they reached out and still honored it and gave me the air conditioner one. To me, that says a lot about them. He was right here when he said he was going to be. She told me I could just purchase another special online through Angie's List. I told her I was going to. I would say they are very good. I would definitely call them again. I plan on having them come out for the Fall for the furnace. She even told me they could check the fireplace. They can show me how to even use the fireplace. I have been here for 5 years and I don't even know how to use it."

"I thought I had a hole in my ducts under the house which I was waiting to be told it's going to be expensive fixing. Video came over crawled under the house then asked to go inside. He went to the thermostat and pointed to my problem. I had the fan on even though I had the a/c off. It's a new thermostat and it wasn't fully explained to me how to use it. He could have come back telling me I needed new duct work, etc. Finding someone that's actually honest in today's world is very rare. I had him go ahead and clean my air vents and dryer out. He is to be commended for his honestly that I told my neighbor and she called to schedule her vents to be cleaned."

Heating and Air Conditioning questions, answered by experts

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

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.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

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.

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.
