How often should I have my heating and air conditioning system maintained?

Maintenance should be performed twice a year. Once before the extreme summer weather and once before the extreme winter weather. Regular maintenance will ensure that your unit will last as long as possible without needing repairs. And believe us it will save you money in the long run, by keeping up the efficiency and cleanliness of your unit. Additionally, some warranties require regular maintenance in order for the warranty terms to be met.

Do you provide free estimates on installations?

YES! We will give you a FREE in-home estimate for an HVAC system or Water Heater. Don’t pay hundreds of unnecessary dollars just for the inspection. Our technicians will work with you to find the best equipment for your home and family’s needs at a price that fits your budget.

What is the average life expectancy of my HVAC system?

An air conditioner can last up to 15 years. But this is ONLY with proper maintenance and servicing. A unit that is not properly cared for may only last 10 years before it starts needing frequent repairs.

Why is my water bill so high?

An unexpected increase in your water bill is a sign that you have a leak. Even if you don’t see the leak, you could have a hidden one.

Why is my electric bill so high in the winter?

Many customers will not notice when their heat pump system is not working. A high electrical bill can be caused by the supplemental heat kit operating to heat your home without heat pump heat. Ensure your system is working properly before the cold days of winter.

What are the benefits of tankless water heaters?

Although some people are perfectly fine with a traditional hot water heater, there are several benefits to using a tankless hot water heater. They never run out of water and can save you money.

Should I use chemicals to clear my drain?

When used too frequently, drain cleaning chemicals are bad for your pipes. They could cause the pipes to deteriorate. There is no replacement for a licensed plumber.
