"Dillon was a great guy and worked fast and efficient. My house is 50 plus years old and the duct work had never been cleaned. Post the work, the house even smelled better. I am in the middle of a complete remodel and living in the house. I had all 11 vent grilles removed -(saved Dillon a pile of time not having to remove and re-install) and I would have thought a discount would have been in order."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

Heating and Air Conditioning FAQs, answered by experts

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril—such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won’t pay for a new one. However, home warranties often cover HVAC repairs and replacements.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
