"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

Heating and Air Conditioning questions, answered by experts

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 frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

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.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.
