"A-maze-ing. These guys were GREAT - I won't be calling anyone else in the future. First, they spoke to the woman in the house exactly as they did to the man - no dumbing it down for the ladies. Physically showed me what was going on and explained it well so I understood what was needed and why. They let me know which repairs needed to be done immediately and which could wait - no hard upsell at any point. They set reasonable expectations for what improvement I could expect with each step. Polite, friendly and helpful, showed up well within the estimated window. Before each visit I got a text with the name and picture of the tech who was on their way and a phone call from them to confirm. In 5 visits I worked with only 2 point people, meaning they weren't having to start from zero every time someone walked in. They charge by the job, not the hour, meaning the work was done quickly, but with quality. I had someone I know take a look at the work and they said everything looked very well-done. After each step they followed up with me by phone to find out if I wanted/needed anything else. In short, I had a shockingly great experience with them and can't recommend them highly enough."

Heating and Air Conditioning questions, answered by experts

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.
