Perhaps the most helpful tool is  Energy Star's® free Home Energy Yardstick. It provides a simple assessment of your home's energy use, compared to similar homes. If your score is in the lower range, it's probably time to replace your HVAC.

If you're still uncertain, no worries. United Mechanical offers a second option: a FREE evaluation for AC replacement to residents in our service area: Fort Myers, Naples, Cape Coral, Punta Gorda, Sarasota, Bradenton & surrounding areas.

A third way is to download our free eBook 12 Tips to Consider Before Replacing Your A/C System. If it is in fact time for replacement, this guide will help you make a wise choice in choosing a new central air conditioning system.

Choose Your HVAC Contractor Wisely

Let's face it... Anybody with a truck and a screwdriver can call himself an HVAC contractor.


There's even a website out there called ContractorsFromHell.com and really...why would that surprise us?!

We've seen so many bad examples of HVAC work, taken so many pictures, and heard so many stories. For example:


She had a limited budget and chose the guy with the lowest price to replace her air conditioner.

He promised he could finish the job in a day. He also convinced Judy to pay up front...and then disappeared.


This couple hired "Lowball Louie" to do a major system replacement including ductwork.

He left some open holes in the attic roof.

It rained and the water poured in ruining the ceiling and warping the floors.

He pulled them up and reinstalled them.

But wait...he failed to let the sub-floor dry out and they warped again!


All they needed was a new air handler and "Lowball Louie's" price was the lowest.

He failed to replace the drain pan.

The water leaked and destroyed the floors and wall.

Are you surprised to hear that Louie disappeared?

Look, we're not telling these stories to scare you.


We're telling you this because there are a lot of sharks in our industry who prey upon unsuspecting customers... 


...and we don't want you to become another one of their victims.


But if you have, there is good news. UMI offers "Do-Overs"  (follow-ups behind the bad guys).

Unfortunately do-overs can be significantly more expensive than hiring us to do the job right the first time.

Our hope is that you'll do your due diligence before hiring an HVAC contractor.

4 Ways to Vet Air Conditioning Companies Before Replacing Your A/C

Do these four things to thoroughly examine each contractor you're considering:


1. Verify that they have a valid license at MyFloridaLicense.com.

Here is our current Certified Mechanical Contractor's license (CMC056872) which qualifies us for all HVAC work.


2. Check the company's reviews on Google, Yelp, Facebook, Better Business Bureau, Nextdoor, and others.


Here are direct links to our online reviews: GOOGLE | YELP | FACEBOOK | BBB | NEXTDOOR

Beware that some business owners & managers will fraudulently add reviews to their own business listings.


Look for 1-star reviews that are followed by multiple 5-star reviews (within days to a week).

This often indicates either the business owner is adding false reviews or (s)he is encouraging friends and coworkers to do so.


They are trying to bury legitimate negative reviews under a mountain of positive fake reviews.

Be wary of those contractors who have high ratings on their own website's review page, but have low ratings on Google, BBB, etc.

This indicates they are cherry picking their reviews, showing you only the best and eliminating the worst.

That's why we recommend checking Google and others first because dishonest businesses cannot hide negative reviews there.

The best they can hope to do is to bury a negative review as previously mentioned.

3. Check the news on television and the internet.

Is the company being investigated for a crime?

Do employees use high-pressure sales tactics?

Have many local residents complained of unfair business practices such as forged signatures on financial documents?


4. Ask the HVAC contractor to provide you with a copy of their liability insurance.

Installing new heating & cooling systems means working with heavy equipment and sometimes injuries happen. 

If an uninsured HVAC contractor injures himself on your property, guess who he's going to sue to pay his medical bills?

That's right, he's going to sue you!

Some uninsured contractors will even fake an injury on your property to try and get an easy payday.

We don't want this to happen to anyone.

That's why we'll provide you with a current copy of our liability insurance as soon as you ask for it.

Take some time to contact a few different companies.

If you think United Mechanical would be a good fit, we'd love to have your business!

During our discussions with you, we may use some terminology that you're unfamiliar with. We like our customers to be well educated to get the best bang for their buck. That's why we've provided this free knowledge panel. Knowledge is power!

Heating & Cooling Knowledge Panel


Air handler

A device used to regulate and circulate air as part of your HVAC system. Typically connects to your ductwork.

British thermal unit (BTU)

This is the amount of heat required to raise the temperature of one pound of water 1°F. One ton of air conditioning is 12,000 BTUs.

Condensing unit

The outdoor piece of equipment that changes the refrigerant from a vapor to a liquid. Sometimes (although erroneously) called the "air conditioner."

COP - Co-efficient of performance

Used in measuring heat pump performance. The higher the COP, the more efficient the heat pump, and the lower the operating costs.

Evaporator coil

The indoor piece of equipment that changes refrigerant from a liquid to a vapor.

Freon / Refrigerant

Liquid or gaseous (colorless, non-flammable) product used as a refrigerant.

HSPF - Heating Season Performance Factor

For heat pumps. The higher the number, the more efficient it is.


Heating, Ventilation, and Air Conditioning

HVAC system

An air handler / condensing unit / coil or heat pump / furnace.

Load calculations

A process of determining the proper size of an HVAC system, heat pump, furnace and/or air conditioner for a home.

MERV rated filters

Minimum Efficiency Reporting Value. The higher the value equates to finer filtration meaning fewer dust particles and other airborne contaminants.


Seasonal Energy Efficiency Ratio. The higher the unit's SEER rating, the more energy efficient it is.

Zoning system

Dividing a home into zones controlled independently of each other - beneficial when areas or rooms have different temperatures (exposure to sun, lots of glass, etc.). Or when some rooms of your home are rarely occupied or used.

The process of dealing with heating, air conditioning, and duct work can be very frustrating.

We do everything possible to prevent situations from arising.


But there's one thing we can guarantee you.

At this point, we pretty much know the speed bumps to expect.

We're also pretty good at coming up with solutions.


Part of it has to do with how we communicate with clients and making them part of the process. 

It's easier that way.

The other part of it has to do with our years of experience.

We've been at this a while...since 1987.

Still every once in a while we see something different and that means creating new solutions.

We like challenges!

Just remember - we're on your side and there's nothing more important than keeping the goal in the front of our minds - you, COMFORTABLE and happy with our recommendations, service, and products.

That's a win-win for all of us! Reach out to us today.
