"I have an annual contract with R.W. Harrell's Pump Service to clean and service the heating and A/C systems at my home. Their employees and always prompt, courteous and professional and ALWAYS do an excellent job with cleaning up before they leave. Their prices are reasonable and I like dealing with locally owned companies as opposed to the nationally owned companies. I would highly recommend R.W. Harrell to all of my friends and relatives for their HVAC needs.

"Jackie and his crew were great. They came in, did the disassembly work quickly, worked with our warranty to get a new part, and installed the unit quickly, taking care of other problems that the previous HVAC company had not taken care of. I would definitely hire them again."

Heating and Air Conditioning FAQs, answered by experts

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

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.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.
