"First & last time customer. Our a/c was working, however noticed a small puddle of water at base of furnace. Service tech came & I told him to check out system since summer season near. He hooked up a gauge at outside condenser unit & said we needed some refrigerant (under 1 lb). I asked if would check for leak & he didn’t seem interested, saying unit is 15 years & not unusual to need refrigerate. Never took side access panel of outside unit during the check nor was temp taken of inside air being circulated. For this we were charged over $200!! Paid bill by check & was told copy of work invoice would be emailed. Over a week went by & no email. Called the office & they reconfirmed by email address & said it would be sent. Still never got it & emailed them from their website portal & they have completely ignored us. There are plenty of other HVAC companies in the area that could have provided a more thorough job for less than $200+, unfortunately I called this one."

"Scam artist plumber. Drain clogged? Let's put down 5 feet of drain snake, flush once and collect $350. All this does is push down the clog further down the line and creates another plumbing job weeks later. His solution? Blaming the customer for dropping "crap" into the toilet and getting it re-clogged, give me a break.... He doesn't stand for his crappy work, and tells you to eff off. Even blurted that he didn't have enough line to finish the job, even though I gave him forward warning of the drain length - the even bigger kicker? He's done it the past multiple times. Unfortunately he was once good, but got extremely lazy."

Heating and Air Conditioning questions, answered by experts

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

HVAC replacement doesn't always include ductwork replacement. It depends on the condition of the existing ductwork. You can reuse your ducts if they are in good shape, adequately sized, and meet current standards. However, if the ducts are damaged, poorly designed, or not appropriately sized for the new system, they may need to be replaced or upgraded. HVAC contractors will assess the condition of the ductwork during the replacement process and recommend any necessary modifications or replacements to ensure the new HVAC system operates efficiently and distributes air effectively throughout your home.

If you run an AC with a dirty filter, it could allow dust and dirt to build up in your ductwork, which could make you sick. At the same time, your air conditioner won’t work as efficiently as it would with a clean filter, likely resulting in less airflow, more wear and tear on your HVAC system, and higher energy bills.

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.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.
