"Hauserâ s sales manager and the field tech were both Very polite, knowledgeable and clearly communicated in as much technical detail as I wanted the repairs they recommended and why. Our previous HVAC service provider had diagnosed loss of AC cooling as a compressor failure and had quoted compressor replacement at over $3500 or even recommended replacing the matched AC & Evap Coil unit costing $5-$7K depending on the efficiency chosen. I approached Hauser for a second opinion diagnosis for loss of AC cooling and they diagnosed it as a deteriorating but not failed compressor and had it running in half an hour with a new replacement run capacitor and an add-on electrical gizmo â compressor saverâ at total cost of under $400."

"I like everything about them. They are personable, the gentlemen who owns the company, Bob, is very polite and careful with anything around the windows they are washing. Anything they have to move to do their job, they make sure to put back. They take great care to clean up after themselves, and respect me and my property. To top everything off, the work they do is always great!

The rates they offer are very friendly and competitive."

Heating and Air Conditioning FAQs, answered by experts

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

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.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

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.
