"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

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.

But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.
