"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."

"Bob came out and provided an estimate which included options for completing the work. Once the work was scheduled he arrived on time and courteous, as usual. New security light of our choosing was installed in our backyard and a GFI outlet were installed in the garage in under an hour. We have used Mr. Handyman Metro East for several projects at our home and continue to use them because of their professionalism, value and customer focus."

"Vinc and his crew were exceptional in the work performed and their interaction with us. There were at least seven guys here and they were all friendly and polite. The site manager Kane is exceptional. The best that I can say about this company is I plan for them to do other work for me on near future."

Heating and Air Conditioning questions, answered by experts

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.
